2015-05-02	Enable AMD64 SHA1 implementations for WIN64	Jussi Kivilinna	1	-2/+10
	* cipher/sha1-avx-amd64.S: Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ELF): New macro to mask lines with ELF specific commands. * cipher/sha1-avx-bmi2-amd64.S: Ditto. * cipher/sha1-ssse3-amd64.S: Ditto. * cipher/sha1.c (USE_SSSE3, USE_AVX, USE_BMI2): Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. [USE_SSSE3 \|\| USE_AVX \|\| USE_BMI2] (ASM_FUNC_ABI) (ASM_EXTRA_STACK): New. (_gcry_sha1_transform_amd64_ssse3, _gcry_sha1_transform_amd64_avx) (_gcry_sha1_transform_amd64_avx_bmi2): Add ASM_FUNC_ABI to prototypes. (transform): Add ASM_EXTRA_STACK to stack burn value. -- Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2013-12-17	Add AVX and AVX/BMI2 implementations for SHA-1	Jussi Kivilinna	1	-0/+420
	* cipher/Makefile.am: Add 'sha1-avx-amd64.S' and 'sha1-avx-bmi2-amd64.S'. * cipher/sha1-avx-amd64.S: New. * cipher/sha1-avx-bmi2-amd64.S: New. * cipher/sha1.c (USE_AVX, USE_BMI2): New. (SHA1_CONTEXT) [USE_AVX]: Add 'use_avx'. (SHA1_CONTEXT) [USE_BMI2]: Add 'use_bmi2'. (sha1_init): Initialize 'use_avx' and 'use_bmi2'. [USE_AVX] (_gcry_sha1_transform_amd64_avx): New. [USE_BMI2] (_gcry_sha1_transform_amd64_bmi2): New. (transform) [USE_BMI2]: Use BMI2 assembly if enabled. (transform) [USE_AVX]: Use AVX assembly if enabled. * configure.ac: Add 'sha1-avx-amd64.lo' and 'sha1-avx-bmi2-amd64.lo'. -- Patch adds AVX (for Sandybridge and Ivybridge) and AVX/BMI2 (for Haswell) optimized implementations of SHA-1. Note: AVX implementation is currently limited to Intel CPUs due to use of SHLD instruction for faster rotations on Sandybrigde.
