lib/libcrypto/arch/amd64: Makefile.inc crypto_arch.h
Added files:
lib/libcrypto/arch/amd64: crypto_cpu_caps.c
Log message:
Provide crypto_cpu_caps_init() for amd64.
This is a CPU capability detection implementation in C, with minimal
inline assembly (for cpuid and xgetbv). This replaces the assembly
mess generated by x86_64cpuid.pl. Rather than populating OPENSSL_ia32cap_P
directly with CPUID output, just set the bits that the remaining
perlasm checks (namely AESNI, AVX, FXSR, INTEL, HT, MMX, PCLMUL, SSE, SSE2
and SSSE3).
