2015-05-14	Enable AMD64 ChaCha20 implementations on WIN64	Jussi Kivilinna	1	-3/+10
	* cipher/chacha20-avx2-amd64.S: Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ELF): New macro to mask lines with ELF specific commands. * cipher/chacha20-sse2-amd64.S: Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ELF): New macro to mask lines with ELF specific commands. * cipher/chacha20-ssse3-amd64.S: Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ELF): New macro to mask lines with ELF specific commands. * cipher/chacha20.c (USE_SSE2, USE_SSSE3, USE_AVX2): Enable when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined. (ASM_FUNC_ABI, ASM_EXTRA_STACK): New. (chacha20_blocks_t, _gcry_chacha20_amd64_sse2_blocks) (_gcry_chacha20_amd64_ssse3_blocks, _gcry_chacha20_amd64_avx2_blocks) (_gcry_chacha20_armv7_neon_blocks, chacha20_blocks): Add ASM_FUNC_ABI. (chacha20_core): Add ASM_EXTRA_STACK. -- Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi>
2014-05-16	chacha20: add SSE2/AMD64 optimized implementation	Jussi Kivilinna	1	-0/+652
	* cipher/Makefile.am: Add 'chacha20-sse2-amd64.S'. * cipher/chacha20-sse2-amd64.S: New. * cipher/chacha20.c (USE_SSE2): New. [USE_SSE2] (_gcry_chacha20_amd64_sse2_blocks): New. (chacha20_do_setkey) [USE_SSE2]: Use SSE2 implementation for blocks function. * configure.ac [host=x86-64]: Add 'chacha20-sse2-amd64.lo'. -- Add Andrew Moon's public domain SSE2 implementation of ChaCha20.
