-This is the readme for the Das U-Boot standalone program smc91111
-
-The main purpose of this is to manage MAC addresses on platforms
-which include the SMC91111 integrated 10/100 MAC Phy, with attached
-EEPROMs.
-
-
-Contents:
-------------------------
-1. Ensuring U-boot's MAC address can be set in hardware
-2. Running the smc91111_eeprom program
-3. Setting MAC addresses
-4. Other things you can do with this
-5. Things to be done.
-
-
-1. Ensuring U-boot's MAC address can be set in hardware
---------------------------------------------------------------------------
-
-On the Internet - MAC addresses are very important. Short for Media
-Access Control address, a hardware address that uniquely identifies
-each node of a network. When things are not unique - bad things
-can happen. This is why U-Boot makes it difficult to change MAC
-addresses.
-
-To find out who has a MAC address, or to purchase MAC addresses, goto
-the IEEE, at:
-http://standards.ieee.org/regauth/oui/index.shtml
-
-To change your MAC address, there can not be a MAC address predefined in
-U-Boot. To ensure that this does not occur, check your
-include/configs/<board_name>.h file, and check to see that the following
-settings are _not_ or commented out there.
-
-#define HARDCODE_MAC 1
-#define CONFIG_ETHADDR 02:80:ad:20:31:b8
-
-The purpose of HARDCODE_MAC is to hardcode the MAC address in software,
-(not what we want), or to preset it to 02:80:ad:20:31:b8 (not what we
-want either).
-
-You can check this in a running U-Boot, by doing a power cycle, then
-before U-Boot tries to do any networking, running the 'printenv' command
-
- BOOT> printenv
-
- ethaddr=02:80:ad:20:31:b8
-
-If you see the 'ethaddr' variable show up, like the above, you need to
-recompile U-Boot, with the above settings commented out of the
-include/configs/<board_name>.h file.
-
-2. Running the smc91111_eeprom program
----------------------------------------------------------------------
-
-After Uboot is compiled, there should be three files of interest:
--rwxr-xr-x 1 8806 2004-10-11 14:00 smc91111_eeprom <- ELF
--rwxr-xr-x 1 3440 2004-10-11 14:00 smc91111_eeprom.bin <- BIN
--rwxr-xr-x 1 9524 2004-10-11 14:00 smc91111_eeprom.srec <- SREC
-
-if there is not, check the examples/Makefile, and ensure there is something
-like for your architecture:
-
- ifeq ($(ARCH),blackfin)
- SREC += smc91111_eeprom.srec
- BIN += smc91111_eeprom.bin smc91111_eeprom
- endif
-
-To load the files: there are two methods: a) serial or b) network. Since
-it is not a good idea to start doing things on the network before the
-MAC address is set, this example will do things over serial.
-
-a) Loading the elf file via the serial port
---------------------------------------------
-Loading the elf is very easy - just ensure that the location
-you specify things to load as is not the load address specified
-in the Makefile.
-
-BOOT> loadb 0x1000000
-
-## Ready for binary (kermit) download to 0x01000000 at 57600 bps...
-
-(type CNTL-\ then C)
-(Back at local machine)
-----------------------------------------------------
-Kermit>send ~/u-boot_1.1.1/examples/smc91111_eeprom
-Kermit>connect
-
-Connecting to /dev/ttyS0, speed 57600
- Escape character: Ctrl-\ (ASCII 28, FS): enabled
-Type the escape character followed by C to get back,
-or followed by ? to see other options.
-----------------------------------------------------
-## Total Size = 0x00002266 = 8806 Bytes
-## Start Addr = 0x01000000
-
-BOOT> bootelf 0x1000000
-
-Loading .text @ 0x00001000 (3440 bytes)
-## Starting application at 0x000010d8 ...
-
-SMC91111>
-
-b) Loading the binary file via the serial port
------------------------------------------------
-For many toolchains, the entry point is not the load point.
-The Load point is a hard coded address from the
-examples/Makefile. The entry point can be found by doing something
-like:
-
- u-boot_1.1.1/examples> bfin-elf-objdump -d smc91111_eeprom |less
-
- smc91111_eeprom: file format elf32-bfin
-
- Disassembly of section .text:
-
- 00001000 <smc91111_eeprom-0xd8>:
- 1000:
- 000010d8 <smc91111_eeprom>:
-
-You can see that the entry point (or the address that should be
-jumped to is 0x10d8). This is also the same as the entry point
-of the elf file.
-
-Now we load it to the actual load location:
-
-BOOT> loadb 0x1000
-
-## Ready for binary (kermit) download to 0x00001000 at 57600 bps...
-
-(Back at pinky.dsl-only.net)
-----------------------------------------------------
-Kermit>send /tftpboot/eeprom.bin
-Kermit>connect
-
-Connecting to /dev/ttyS0, speed 57600
- Escape character: Ctrl-\ (ASCII 28, FS): enabled
-Type the escape character followed by C to get back,
-or followed by ? to see other options.
-----------------------------------------------------
-## Total Size = 0x00000d70 = 3440 Bytes
-## Start Addr = 0x00001000
-
-BOOT> go 0x10D8
-
-## Starting application at 0x000010D8 ...
-
-SMC91111>
-
-3. Setting MAC addresses
---------------------------------------------------------------------------
-
-The MAC address can be stored in four locations:
-
--Boot environmental variable in Flash <- can not change, without
- re-flashing U-boot.
-U-Boot environental variable <- can not change, without
- resetting board/U-Boot
-LAN91C111 Registers <- volitle
-LAN91C111 EEPROM <- Non Volitle
-
-If you have not activated the network, and do not have a hardcoded
-or pre-assigned MAC address in U-boot, the environmental variables
-should be blank, and allow you to set things one time.
-
-To set the EEPROM MAC address to 12:34:56:78:9A:BC
-
-SMC91111> W E 20 3412
-
-Writing EEPROM register 20 with 3412
-SMC91111> W E 21 7856
-
-Writing EEPROM register 21 with 7856
-SMC91111> W E 22 BC9A
-
-Writing EEPROM register 22 with bc9a
-EEPROM contents copied to MAC
-SMC91111> P
-
-Current MAC Address in SMSC91111 12:34:56:78:9a:bc
-Current MAC Address in EEPROM 12:34:56:78:9a:bc
-
-(CNTRL-C to exit)
-SMC91111> ## Application terminated, rc = 0x0
-
-BOOT> reset
-U-Boot 1.1.1 (gcc version: 3.3.3)
-Release Version Beta released on Oct 10 2004 - 00:34:35
-Blackfin support by LG Soft India
-For further information please check this link http://www.blackfin.uclinux.org
-BOOT> ping 192.168.0.4
-
-Using MAC Address 12:34:56:78:9A:BC
-host 192.168.0.4 is alive
-
-
-4. Other things that you can do
---------------------------------------------------------------------------
-After the stand alone application is running, there are a few options:
- - P : Print the MAC
- - D : Dump the LAN91C111 EEPROM contents
- - M : Dump the LAN91C111 MAC contents
- - C : Copies the MAC address from the EEPROM to the LAN91C111
- - W : Write a register in the EEPROM or in the MAC

- * A very simple thread/schedular model:
- * - only one master thread, and no parent child relation maintained
- * - parent thread cannot be stopped or deleted
- * - no permissions or credentials
- * - no elaborate safety checks
- * - cooperative multi threading
- * - Simple round-robin scheduleing with no priorities
- * - no metering/statistics collection
- *
- * Basic idea of implementing this is to allow more than one tests to
- * execute "simultaneously".
- *
- * This may be modified such thread_yield may be called in syscalls, and

+This is the readme for the Das U-Boot standalone program smc91111
+
+The main purpose of this is to manage MAC addresses on platforms
+which include the SMC91111 integrated 10/100 MAC Phy, with attached
+EEPROMs.
+
+
+Contents:
+------------------------
+1. Ensuring U-boot's MAC address can be set in hardware
+2. Running the smc91111_eeprom program
+3. Setting MAC addresses
+4. Other things you can do with this
+5. Things to be done.
+
+
+1. Ensuring U-boot's MAC address can be set in hardware
+--------------------------------------------------------------------------
+
+On the Internet - MAC addresses are very important. Short for Media
+Access Control address, a hardware address that uniquely identifies
+each node of a network. When things are not unique - bad things
+can happen. This is why U-Boot makes it difficult to change MAC
+addresses.
+
+To find out who has a MAC address, or to purchase MAC addresses, goto
+the IEEE, at:
+http://standards.ieee.org/regauth/oui/index.shtml
+
+To change your MAC address, there can not be a MAC address predefined in
+U-Boot. To ensure that this does not occur, check your
+include/configs/<board_name>.h file, and check to see that the following
+settings are _not_ or commented out there.
+
+#define HARDCODE_MAC 1
+#define CONFIG_ETHADDR 02:80:ad:20:31:b8
+
+The purpose of HARDCODE_MAC is to hardcode the MAC address in software,
+(not what we want), or to preset it to 02:80:ad:20:31:b8 (not what we
+want either).
+
+You can check this in a running U-Boot, by doing a power cycle, then
+before U-Boot tries to do any networking, running the 'printenv' command
+
+ BOOT> printenv
+
+ ethaddr=02:80:ad:20:31:b8
+
+If you see the 'ethaddr' variable show up, like the above, you need to
+recompile U-Boot, with the above settings commented out of the
+include/configs/<board_name>.h file.
+
+2. Running the smc91111_eeprom program
+---------------------------------------------------------------------
+
+After Uboot is compiled, there should be three files of interest:
+-rwxr-xr-x 1 8806 2004-10-11 14:00 smc91111_eeprom <- ELF
+-rwxr-xr-x 1 3440 2004-10-11 14:00 smc91111_eeprom.bin <- BIN
+-rwxr-xr-x 1 9524 2004-10-11 14:00 smc91111_eeprom.srec <- SREC
+
+if there is not, check the examples/Makefile, and ensure there is something
+like for your architecture:
+
+ ifeq ($(ARCH),blackfin)
+ SREC += smc91111_eeprom.srec
+ BIN += smc91111_eeprom.bin smc91111_eeprom
+ endif
+
+To load the files: there are two methods: a) serial or b) network. Since
+it is not a good idea to start doing things on the network before the
+MAC address is set, this example will do things over serial.
+
+a) Loading the elf file via the serial port
+--------------------------------------------
+Loading the elf is very easy - just ensure that the location
+you specify things to load as is not the load address specified
+in the Makefile.
+
+BOOT> loadb 0x1000000
+
+## Ready for binary (kermit) download to 0x01000000 at 57600 bps...
+
+(type CNTL-\ then C)
+(Back at local machine)
+----------------------------------------------------
+Kermit>send ~/u-boot_1.1.1/examples/smc91111_eeprom
+Kermit>connect
+
+Connecting to /dev/ttyS0, speed 57600
+ Escape character: Ctrl-\ (ASCII 28, FS): enabled
+Type the escape character followed by C to get back,
+or followed by ? to see other options.
+----------------------------------------------------
+## Total Size = 0x00002266 = 8806 Bytes
+## Start Addr = 0x01000000
+
+BOOT> bootelf 0x1000000
+
+Loading .text @ 0x00001000 (3440 bytes)
+## Starting application at 0x000010d8 ...
+
+SMC91111>
+
+b) Loading the binary file via the serial port
+-----------------------------------------------
+For many toolchains, the entry point is not the load point.
+The Load point is a hard coded address from the
+examples/Makefile. The entry point can be found by doing something
+like:
+
+ u-boot_1.1.1/examples> bfin-elf-objdump -d smc91111_eeprom |less
+
+ smc91111_eeprom: file format elf32-bfin
+
+ Disassembly of section .text:
+
+ 00001000 <smc91111_eeprom-0xd8>:
+ 1000:
+ 000010d8 <smc91111_eeprom>:
+
+You can see that the entry point (or the address that should be
+jumped to is 0x10d8). This is also the same as the entry point
+of the elf file.
+
+Now we load it to the actual load location:
+
+BOOT> loadb 0x1000
+
+## Ready for binary (kermit) download to 0x00001000 at 57600 bps...
+
+(Back at pinky.dsl-only.net)
+----------------------------------------------------
+Kermit>send /tftpboot/eeprom.bin
+Kermit>connect
+
+Connecting to /dev/ttyS0, speed 57600
+ Escape character: Ctrl-\ (ASCII 28, FS): enabled
+Type the escape character followed by C to get back,
+or followed by ? to see other options.
+----------------------------------------------------
+## Total Size = 0x00000d70 = 3440 Bytes
+## Start Addr = 0x00001000
+
+BOOT> go 0x10D8
+
+## Starting application at 0x000010D8 ...
+
+SMC91111>
+
+3. Setting MAC addresses
+--------------------------------------------------------------------------
+
+The MAC address can be stored in four locations:
+
+-Boot environmental variable in Flash <- can not change, without
+ re-flashing U-boot.
+U-Boot environental variable <- can not change, without
+ resetting board/U-Boot
+LAN91C111 Registers <- volitle
+LAN91C111 EEPROM <- Non Volitle
+
+If you have not activated the network, and do not have a hardcoded
+or pre-assigned MAC address in U-boot, the environmental variables
+should be blank, and allow you to set things one time.
+
+To set the EEPROM MAC address to 12:34:56:78:9A:BC
+
+SMC91111> W E 20 3412
+
+Writing EEPROM register 20 with 3412
+SMC91111> W E 21 7856

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
- When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-\f
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard. To achieve this, non-free programs must be
-allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-\f
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-\f
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-\f
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-\f
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-\f
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-\f
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-\f
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- How to Apply These Terms to Your New Libraries
-
- If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
- To apply these terms, attach the following notices to the library. It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
- <one line to give the library's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This library is free software; you can redistribute it and/or
- modify it under the terms of the GNU Lesser General Public
- License as published by the Free Software Foundation; either
- version 2.1 of the License, or (at your option) any later version.
-
- This library is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
- Lesser General Public License for more details.
-
- You should have received a copy of the GNU Lesser General Public
- License along with this library; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the

Recommendations
---------------
-To increase compression ratio for LZMA compressing it's desirable
+To increase the compression ratio for LZMA compressing it's desirable
to have aligned data (if it's possible) and also it's desirable to locate
data in such order, where code is grouped in one place and data is
grouped in other place (it's better than such mixing: code, data, code,
data, ...).
-Using Filters
--------------
-You can increase compression ratio for some data types, using
+Filters

+You can increase the compression ratio for some data types, using
special filters before compressing. For example, it's possible to

-You can find C/C++ source code of such filters in folder "7zip/Compress/Branch"
+You can find C source code of such filters in C/Bra*.* files
-You can check compression ratio gain of these filters with such
+You can check the compression ratio gain of these filters with such
7-Zip commands (example for ARM code):
No filter:
7z a a1.7z a.bin -m0=lzma
With filter for little-endian ARM code:
- 7z a a2.7z a.bin -m0=bc_arm -m1=lzma
-
-With filter for big-endian ARM code (using additional Swap4 filter):
- 7z a a3.7z a.bin -m0=swap4 -m1=bc_arm -m2=lzma
+ 7z a a2.7z a.bin -m0=arm -m1=lzma
It works in such manner:
Compressing = Filter_encoding + LZMA_encoding
These filters convert CALL (calling procedure) instructions
from relative offsets to absolute addresses, so such data becomes more

-(about 20 lines of C++), so you can convert it from C++ version yourself.

ANSI-C LZMA Decoder
~~~~~~~~~~~~~~~~~~~
-To compile ANSI-C LZMA Decoder you can use one of the following files sets:
-1) LzmaDecode.h + LzmaDecode.c + LzmaTest.c (fastest version)
-2) LzmaDecode.h + LzmaDecodeSize.c + LzmaTest.c (old size-optimized version)
-3) LzmaStateDecode.h + LzmaStateDecode.c + LzmaStateTest.c (zlib-like interface)
+Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
+If you want to use old interfaces you can download previous version of LZMA SDK
+from sourceforge.net site.
+
+To use ANSI-C LZMA Decoder you need the following files:
+1) LzmaDec.h + LzmaDec.c + Types.h
+LzmaUtil/LzmaUtil.c is example application that uses these files.
Memory requirements for LZMA decoding
-------------------------------------
-LZMA decoder doesn't allocate memory itself, so you must
-allocate memory and send it to LZMA.
-
Stack usage of LZMA decoding function for local variables is not
-larger than 200 bytes.
+larger than 200-400 bytes.
+
+LZMA Decoder uses dictionary buffer and internal state structure.
+Internal state structure consumes
+ state_size = (4 + (1.5 << (lc + lp))) KB
+by default (lc=3, lp=0), state_size = 16 KB.
+
How To decompress data
----------------------
-LZMA Decoder (ANSI-C version) now supports 5 interfaces:
+LZMA Decoder (ANSI-C version) now supports 2 interfaces:
1) Single-call Decompressing
-2) Single-call Decompressing with input stream callback
-3) Multi-call Decompressing with output buffer
-4) Multi-call Decompressing with input callback and output buffer
-5) Multi-call State Decompressing (zlib-like interface)
-
-Variant-5 is similar to Variant-4, but Variant-5 doesn't use callback functions.
-
-Decompressing steps
--------------------
-
-1) read LZMA properties (5 bytes):
- unsigned char properties[LZMA_PROPERTIES_SIZE];
-
-2) read uncompressed size (8 bytes, little-endian)
+2) Multi-call State Decompressing (zlib-like interface)
-3) Decode properties:
+You must use external allocator:
+Example:
+void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
+void SzFree(void *p, void *address) { p = p; free(address); }
+ISzAlloc alloc = { SzAlloc, SzFree };
- CLzmaDecoderState state; /* it's 24-140 bytes structure, if int is 32-bit */
+You can use p = p; operator to disable compiler warnings.
- if (LzmaDecodeProperties(&state.Properties, properties, LZMA_PROPERTIES_SIZE) != LZMA_RESULT_OK)
- return PrintError(rs, "Incorrect stream properties");
-4) Allocate memory block for internal Structures:
-
- state.Probs = (CProb *)malloc(LzmaGetNumProbs(&state.Properties) * sizeof(CProb));
- if (state.Probs == 0)
- return PrintError(rs, kCantAllocateMessage);
-
- LZMA decoder uses array of CProb variables as internal structure.
- By default, CProb is unsigned_short. But you can define _LZMA_PROB32 to make
- it unsigned_int. It can increase speed on some 32-bit CPUs, but memory
- usage will be doubled in that case.
-
-
-5) Main Decompressing
-
-You must use one of the following interfaces:
-
-5.1 Single-call Decompressing
------------------------------
+Single-call Decompressing
+-------------------------
When to use: RAM->RAM decompressing
-Compile files: LzmaDecode.h, LzmaDecode.c
+Compile files: LzmaDec.h + LzmaDec.c + Types.h
Compile defines: no defines
Memory Requirements:
- Input buffer: compressed size
- Output buffer: uncompressed size
- - LZMA Internal Structures (~16 KB for default settings)
+ - LZMA Internal Structures: state_size (16 KB for default settings)
Interface:
- int res = LzmaDecode(&state,
- inStream, compressedSize, &inProcessed,
- outStream, outSize, &outProcessed);
+ int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
+ const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode,
+ ELzmaStatus *status, ISzAlloc *alloc);
+ In:
+ dest - output data
+ destLen - output data size
+ src - input data
+ srcLen - input data size
+ propData - LZMA properties (5 bytes)
+ propSize - size of propData buffer (5 bytes)
+ finishMode - It has meaning only if the decoding reaches output limit (*destLen).
+ LZMA_FINISH_ANY - Decode just destLen bytes.
+ LZMA_FINISH_END - Stream must be finished after (*destLen).
+ You can use LZMA_FINISH_END, when you know that
+ current output buffer covers last bytes of stream.
+ alloc - Memory allocator.
+
+ Out:
+ destLen - processed output size
+ srcLen - processed input size
+
+ Output:
+ SZ_OK
+ status:
+ LZMA_STATUS_FINISHED_WITH_MARK
+ LZMA_STATUS_NOT_FINISHED
+ LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
+ SZ_ERROR_DATA - Data error
+ SZ_ERROR_MEM - Memory allocation error
+ SZ_ERROR_UNSUPPORTED - Unsupported properties
+ SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
+
+ If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
+ and output value of destLen will be less than output buffer size limit.
+
+ You can use multiple checks to test data integrity after full decompression:
+ 1) Check Result and "status" variable.
+ 2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
+ 3) Check that output(srcLen) = compressedSize, if you know real compressedSize.
+ You must use correct finish mode in that case. */

+ - Buffer for output stream: any size (for example, 16 KB)
+ - LZMA Internal Structures: state_size (16 KB for default settings)
+ - LZMA dictionary (dictionary size is encoded in LZMA properties header)
-Interface:
- typedef struct _CBuffer
- {
- ILzmaInCallback InCallback;
- FILE *File;
- unsigned char Buffer[kInBufferSize];
- } CBuffer;
+1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
+ unsigned char header[LZMA_PROPS_SIZE + 8];
+ ReadFile(inFile, header, sizeof(header)
- int LzmaReadCompressed(void *object, const unsigned char **buffer, SizeT *size)
+2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
+
+ CLzmaDec state;
+ LzmaDec_Constr(&state);
+ res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
+ if (res != SZ_OK)
+ return res;
+
+3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
+
+ LzmaDec_Init(&state);
+ for (;;)
{
- CBuffer *bo = (CBuffer *)object;
- *buffer = bo->Buffer;
- *size = MyReadFile(bo->File, bo->Buffer, kInBufferSize);
- return LZMA_RESULT_OK;

+
+
+How To compress data
+--------------------
+Compile files: LzmaEnc.h + LzmaEnc.c + Types.h +
+LzFind.c + LzFind.h + LzFindMt.c + LzFindMt.h + LzHash.h
-5.3 Multi-call decompressing with output buffer
------------------------------------------------
-When to use: RAM->File decompressing
-Compile files: LzmaDecode.h, LzmaDecode.c
-Compile defines: _LZMA_OUT_READ
Memory Requirements:
- - Input buffer: compressed size
- - Buffer for output stream: any size (for example, 16 KB)
- - LZMA Internal Structures (~16 KB for default settings)
- - LZMA dictionary (dictionary size is encoded in stream properties)
+ - (dictSize * 11.5 + 6 MB) + state_size
-Interface:
+Lzma Encoder can use two memory allocators:
+1) alloc - for small arrays.
+2) allocBig - for big arrays.
- state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+For example, you can use Large RAM Pages (2 MB) in allocBig allocator for
+better compression speed. Note that Windows has bad implementation for
+Large RAM Pages.
+It's OK to use same allocator for alloc and allocBig.
- LzmaDecoderInit(&state);
- do
- {
- LzmaDecode(&state,
- inBuffer, inAvail, &inProcessed,
- g_OutBuffer, outAvail, &outProcessed);
- inAvail -= inProcessed;
- inBuffer += inProcessed;
- }
- while you need more bytes
- see LzmaTest.c for more details.
+Single-call Compression with callbacks
+--------------------------------------
+Check C/LzmaUtil/LzmaUtil.c as example,
-5.4 Multi-call decompressing with input callback and output buffer
-------------------------------------------------------------------
-When to use: File->File decompressing
-Compile files: LzmaDecode.h, LzmaDecode.c
-Compile defines: _LZMA_IN_CB, _LZMA_OUT_READ
-Memory Requirements:
- - Buffer for input stream: any size (for example, 16 KB)
- - Buffer for output stream: any size (for example, 16 KB)
- - LZMA Internal Structures (~16 KB for default settings)
- - LZMA dictionary (dictionary size is encoded in stream properties)
+When to use: file->file decompressing
-Interface:
+1) you must implement callback structures for interfaces:
+ISeqInStream
+ISeqOutStream
+ICompressProgress
+ISzAlloc
- state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
+static void SzFree(void *p, void *address) { p = p; MyFree(address); }
+static ISzAlloc g_Alloc = { SzAlloc, SzFree };
- LzmaDecoderInit(&state);
- do
- {
- LzmaDecode(&state,
- &bo.InCallback,
- g_OutBuffer, outAvail, &outProcessed);
- }
- while you need more bytes
+ CFileSeqInStream inStream;
+ CFileSeqOutStream outStream;
- see LzmaTest.c for more details:
+ inStream.funcTable.Read = MyRead;
+ inStream.file = inFile;
+ outStream.funcTable.Write = MyWrite;
+ outStream.file = outFile;
-5.5 Multi-call State Decompressing (zlib-like interface)
-------------------------------------------------------------------
-When to use: file->file decompressing
-Compile files: LzmaStateDecode.h, LzmaStateDecode.c
-Compile defines:
-Memory Requirements:
- - Buffer for input stream: any size (for example, 16 KB)
- - Buffer for output stream: any size (for example, 16 KB)
- - LZMA Internal Structures (~16 KB for default settings)
- - LZMA dictionary (dictionary size is encoded in stream properties)
+2) Create CLzmaEncHandle object;
-Interface:
+ CLzmaEncHandle enc;
- state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);
+ enc = LzmaEnc_Create(&g_Alloc);
+ if (enc == 0)
+ return SZ_ERROR_MEM;
- LzmaDecoderInit(&state);
- do
- {
- res = LzmaDecode(&state,
- inBuffer, inAvail, &inProcessed,
- g_OutBuffer, outAvail, &outProcessed,
- finishDecoding);
- inAvail -= inProcessed;
- inBuffer += inProcessed;
- }
- while you need more bytes
+3) initialize CLzmaEncProps properties;
- see LzmaStateTest.c for more details:
+ LzmaEncProps_Init(&props);
+ Then you can change some properties in that structure.
-6) Free all allocated blocks
+4) Send LZMA properties to LZMA Encoder
+ res = LzmaEnc_SetProps(enc, &props);
-Note
-----
-LzmaDecodeSize.c is size-optimized version of LzmaDecode.c.
-But compiled code of LzmaDecodeSize.c can be larger than
-compiled code of LzmaDecode.c. So it's better to use
-LzmaDecode.c in most cases.
+5) Write encoded properties to header
+ Byte header[LZMA_PROPS_SIZE + 8];
+ size_t headerSize = LZMA_PROPS_SIZE;
+ UInt64 fileSize;
+ int i;
-EXIT codes
------------
+ res = LzmaEnc_WriteProperties(enc, header, &headerSize);
+ fileSize = MyGetFileLength(inFile);
+ for (i = 0; i < 8; i++)
+ header[headerSize++] = (Byte)(fileSize >> (8 * i));
+ MyWriteFileAndCheck(outFile, header, headerSize)
-LZMA decoder can return one of the following codes:
+6) Call encoding function:
+ res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable,
+ NULL, &g_Alloc, &g_Alloc);
-#define LZMA_RESULT_OK 0
-#define LZMA_RESULT_DATA_ERROR 1
+7) Destroy LZMA Encoder Object
+ LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
-If you use callback function for input data and you return some
-error code, LZMA Decoder also returns that code.
+If callback function return some error code, LzmaEnc_Encode also returns that code.
-LZMA Defines
-------------
+Single-call RAM->RAM Compression
+--------------------------------
-_LZMA_IN_CB - Use callback for input data
+Single-call RAM->RAM Compression is similar to Compression with callbacks,
+but you provide pointers to buffers instead of pointers to stream callbacks:
-_LZMA_OUT_READ - Use read function for output data
+HRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
+ CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark,
+ ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
-_LZMA_LOC_OPT - Enable local speed optimizations inside code.
- _LZMA_LOC_OPT is only for LzmaDecodeSize.c (size-optimized version).
- _LZMA_LOC_OPT doesn't affect LzmaDecode.c (speed-optimized version)
- and LzmaStateDecode.c
+Return code:
+ SZ_OK - OK
+ SZ_ERROR_MEM - Memory allocation error
+ SZ_ERROR_PARAM - Incorrect paramater
+ SZ_ERROR_OUTPUT_EOF - output buffer overflow
+ SZ_ERROR_THREAD - errors in multithreading functions (only for Mt version)
-_LZMA_PROB32 - It can increase speed on some 32-bit CPUs,
- but memory usage will be doubled in that case
-_LZMA_UINT32_IS_ULONG - Define it if int is 16-bit on your compiler
- and long is 32-bit.
-_LZMA_SYSTEM_SIZE_T - Define it if you want to use system's size_t.
- You can use it to enable 64-bit sizes supporting
+LZMA Defines
+------------
+
+_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
+
+_LZMA_PROB32 - It can increase the speed on some 32-bit CPUs, but memory usage for
+ some structures will be doubled in that case.
+_LZMA_UINT32_IS_ULONG - Define it if int is 16-bit on your compiler and long is 32-bit.
+
+_LZMA_NO_SYSTEM_SIZE_T - Define it if you don't want to use size_t type.
C++ LZMA Encoder/Decoder
~~~~~~~~~~~~~~~~~~~~~~~~
C++ LZMA code use COM-like interfaces. So if you want to use it,
you can study basics of COM/OLE.
+C++ LZMA code is just wrapper over ANSI-C code.
-By default, LZMA Encoder contains all Match Finders.
-But for compressing it's enough to have just one of them.
-So for reducing size of compressing code you can define:
- #define COMPRESS_MF_BT
- #define COMPRESS_MF_BT4
-and it will use only bt4 match finder.
+C++ Notes
+~~~~~~~~~~~~~~~~~~~~~~~~
+If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
+you must check that you correctly work with "new" operator.
+7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
+So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
+operator new(size_t size)
+{
+ void *p = ::malloc(size);
+ if (p == 0)
+ throw CNewException();
+ return p;
+}
+If you use MSCV that throws exception for "new" operator, you can compile without
+"NewHandler.cpp". So standard exception will be used. Actually some code of
+7-Zip catches any exception in internal code and converts it to HRESULT code.
+So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.
