Martin Storsjö	570d4b2186	x86: h264: Don't keep data in the redzone across function calls on 64 bit unix We know that the called function (ff_chroma_inter_body_mmxext) doesn't touch the redzone, and thus will be kept intact - thus, this doesn't fix any bug per se. However, valgrind's memcheck tool intentionally assumes that the redzone is clobbered on every function call and function return (see a long comment in valgrind/memcheck/mc_main.c). This avoids false positives in that tool, at the cost of an extra stack pointer adjustment. The other alternative would be a valgrind suppression for this issue, but that's an extra burden for everybody that wants to run libavcodec within valgrind.

Christophe Gisquet	4cb6964244	dcadec: simplify decoding of VQ high frequencies The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.	12 years ago
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>	12 years ago
