Hello,
I've found following problem with compilation of OpenSSL on Solaris x86
platform:
I use gcc 3.3 from www.sunfreeware.com, which is configured to use Sun
native assembler.
It seems that Sun assembler doesn't know anything about SSE2
instruction, and compilation of assembler file x86cpuid_elf.s fails on
PXOR sse instruction.
There is configuration option no-sse2 of openssl Configure script, but
it doesn't prevent x86cpuid.pl from generating SSE2 pxor instruction.
These pxor instructions are skipped anyway if absense of SSE2 is detected
run-time.
x86cpuid.pl receives full set of C compiler flags, including
OPENSS_IA32_SSE2 flag, which is set only if SSE2 instructions are
enabled.
Attached patch fixes this problem by adding check for OPENSSL_IA32_SSE2
command line flag to x86cpuid.pl and skipping section between runtime
SSE2 check and label no_sse2, if this flag is not found.
Patch is made against 20050516 CVS snapshot.
Sincerely yours, Victor Wagner
