Henrik Gramner	ad7d7d4f6a	x86inc: Remove .rodata kludges The Mach-O bug was fixed in yasm 0.8.0 and we don't support versions that old anymore. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	3e2fa991db	x86inc: remove misaligned cpu flag Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether.

Jason Garrett-Glaser	7115566541	x86inc: various minor backports from x264 Small backports that sneaked into other asm commits in x264. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Derek Buitenhuis	47f9d7ce54	x86inc: Check for __OUTPUT_FORMAT__ having a value of "x64" This is also a valid value for WIN64. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	bbe4a6db44	x86inc: Utilize the shadow space on 64-bit Windows Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Loren Merritt	3fb78e99a0	x86inc: create xm# and ym#, analagous to m# For when we want to mix simd sizes within one function. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Loren Merritt	49ebe3f9fe	x86inc: fix some corner cases of SWAP SWAP with >=3 named (rather than numbered) args PERMUTE followed by SWAP with 2 named args used to produce the wrong permutation Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	63f0d62310	x86inc: Use SSE instead of SSE2 for copying data Reduces code size because movaps/movups is one byte shorter than movdqa/movdqu. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	ad76e6e7e1	x86inc: Set ELF hidden visibility for global constants Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Loren Merritt	25cb0c1a1e	x86inc: activate REP_RET automatically Now RET checks whether it immediately follows a branch, so the programmer dosen't have to keep track of that condition. REP_RET is still needed manually when it's a branch target, but that's much rarer. The implementation involves lots of spurious labels, but that's OK because we strip them.

Alex Smith	33b88f2a4a	msvc/icl: Use __declspec(noinline) Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Alex Smith	09f2581dc5	msvc/icl: Use __declspec(deprecated) Prior to this on msvc/icl there was no handling of deprecated functions and the deprecated warning was disabled. After enabling there are a number of warnings relating to the CRT and the use of the non-secure versions of several functions. Defining _CRT_SECURE_NO_WARNINGS silences these warnings.

Nicolas George	d5b58f678d	tools: add benchmark for crypto functions. The benchmark tests the speed of the following algorithms: MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128. It can optionally be built to perform the same benchmark on other crypto libraries, for comparison purposes. The supported libraries are: - crypto: OpenSSL's libcrypto; - gcrypt: GnuTLS's libgcrypt; - tomcrypt: LibTomCrypt To enable them, use this syntax: make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench They do not need to have been enabled in configure.	11 years ago
