4 # Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
5 # project. The module is, however, dual licensed under OpenSSL and
6 # CRYPTOGAMS licenses depending on where you obtain it. For further
7 # details see http://www.openssl.org/~appro/cryptogams/.
8 # ====================================================================
10 # I let hardware handle unaligned input, except on page boundaries
11 # (see below for details). Otherwise straightforward implementation
12 # with X vector in register bank. The module is big-endian [which is
13 # not big deal as there're no little-endian targets left around].

21 # (*) 64-bit code in 32-bit application context, which actually is
22 # on TODO list. It should be noted that for safe deployment in
23 # 32-bit *mutli-threaded* context asyncronous signals should be
24 # blocked upon entry to SHA512 block routine. This is because
25 # 32-bit signaling procedure invalidates upper halves of GPRs.
26 # Context switch procedure preserves them, but not signaling:-(
28 # Second version is true multi-thread safe. Trouble with the original
29 # version was that it was using thread local storage pointer register.
30 # Well, it scrupulously preserved it, but the problem would arise the
31 # moment asynchronous signal was delivered and signal handler would
32 # dereference the TLS pointer. While it's never the case in openssl
33 # application or test suite, we have to respect this scenario and not
34 # use TLS pointer register. Alternative would be to require caller to
35 # block signals prior calling this routine. For the record, in 32-bit
36 # context R2 serves as TLS pointer, while in 64-bit context - R13.
