Hi, was that for me to check? I've done it anyway by patching
x86_64-xlate.pl to 1.25.2.7
<http://cvs.openssl.org/fileview?f=openssl/crypto/perlasm/x86_64-xlate.pl&v=1.25.2.7>
, removing my old patched x86_64cpuid.asm, and building with nmake -f
ms\nt.mak. The results looks great as far as I'm concerned:
No warnings, and the *OPENSSL_ia32cap_loc() address is now initialized
in our application.
However, I've not made a complete openssl rebuild, so no idea of
possible impact on other assembler code, and I've not ventured trying
microsoft masm. And I still don't have a box for running a "make test"
on x64.
Thanks for the quick resolution!
