Author	SHA1	Message	Date
Christophe Gisquet	08e3ea60ff	x86: synth filter float: implement SSE2 version ... Timings for Arrandale: C SSE win32: 2108 334 win64: 1152 322 Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with the jmp destination being aligned. Unrolling for ARCH_X86_64 is a 20 cycles gain. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	ad507d7907	x86: dcadsp: implement SSE lfe_dir ... Results for Arrandale/Windows: 32: 1670 -> 316 64: 728 -> 298 Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	5b59a9fc61	x86: dcadsp: implement int8x8_fmul_int32 ... For the callable function (as opposed to the inline one): C SSE SSE2 SSE4 Win32: 47 42 29 26 Win64: 30 33 25 23 The SSE version is neither compiled nor set for ARCH_X86_64, as the inlinable function takes over.

Diego Biurrun	6369ba3c9c	x86: avcodec: Use convenience macros to check for CPU flags	12 years ago
Diego Biurrun	3ac7fa81b2	Consistently use "cpu_flags" as variable/parameter name for CPU flags	12 years ago
Diego Biurrun	c9f933b5b6	Add av_cold attributes to arch-specific init functions	12 years ago
Ronald S. Bultje	2e4bb99f4d	vorbisdsp: convert x86 simd functions from inline asm to yasm.	12 years ago
Ronald S. Bultje	1768e43ceb	vorbisdsp: change block_size type from int to intptr_t. ... This saves one instruction in the x86-64 assembly.	12 years ago
Ronald S. Bultje	fef906c77c	Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. ... Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.	12 years ago
