Subject: Only build the body of e_padlock when there are lower level routines
X-Git-Tag: OpenSSL_1_1_1-pre1~3065
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7b176a549ea374fc9b64c3fa7f0812239528b696;p=oweals%2Fopenssl.git

Only build the body of e_padlock when there are lower level routines

engines/e_padlock.c assumes that for all x86 and x86_64 platforms, the
lower level routines will be present.  However, that's not always
true, for example for solaris-x86-cc, and that leads to build errors.

The better solution is to have configure detect if the lower level
padlock routines are being built, and define the macro PADLOCK_ASM if
they are, and use that macro in our C code.
