2015-05-14	Enable AMD64 Poly1305 implementations on WIN64	Jussi Kivilinna	1	-7/+15
	* cipher/poly1305-avx2-amd64.S: Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ELF): New macro to mask lines with ELF specific commands. * cipher/poly1305-sse2-amd64.S: Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ELF): New macro to mask lines with ELF specific commands. * cipher/poly1305-internal.h (POLY1305_SYSV_FUNC_ABI): New. (POLY1305_USE_SSE2, POLY1305_USE_AVX2): Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (OPS_FUNC_ABI): New. (poly1305_ops_t): Use OPS_FUNC_ABI. * cipher/poly1305.c (_gcry_poly1305_amd64_sse2_init_ext) (_gcry_poly1305_amd64_sse2_finish_ext) (_gcry_poly1305_amd64_sse2_blocks, _gcry_poly1305_amd64_avx2_init_ext) (_gcry_poly1305_amd64_avx2_finish_ext) (_gcry_poly1305_amd64_avx2_blocks, _gcry_poly1305_armv7_neon_init_ext) (_gcry_poly1305_armv7_neon_finish_ext) (_gcry_poly1305_armv7_neon_blocks, poly1305_init_ext_ref32) (poly1305_blocks_ref32, poly1305_finish_ext_ref32) (poly1305_init_ext_ref8, poly1305_blocks_ref8) (poly1305_finish_ext_ref8): Use OPS_FUNC_ABI. -- Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2014-05-16	poly1305: add AMD64/AVX2 optimized implementation	Jussi Kivilinna	1	-0/+954
	* cipher/Makefile.am: Add 'poly1305-avx2-amd64.S'. * cipher/poly1305-avx2-amd64.S: New. * cipher/poly1305-internal.h (POLY1305_USE_AVX2) (POLY1305_AVX2_BLOCKSIZE, POLY1305_AVX2_STATESIZE) (POLY1305_AVX2_ALIGNMENT): New. (POLY1305_LARGEST_BLOCKSIZE, POLY1305_LARGEST_STATESIZE) (POLY1305_STATE_ALIGNMENT): Use AVX2 versions when needed. * cipher/poly1305.c [POLY1305_USE_AVX2] (_gcry_poly1305_amd64_avx2_init_ext) (_gcry_poly1305_amd64_avx2_finish_ext) (_gcry_poly1305_amd64_avx2_blocks, poly1305_amd64_avx2_ops): New. (_gcry_poly1305_init) [POLY1305_USE_AVX2]: Use AVX2 implementation if AVX2 supported by CPU. * configure.ac [host=x86_64]: Add 'poly1305-avx2-amd64.lo'. -- Add Andrew Moon's public domain AVX2 implementation of Poly1305.
