Anton Khirnov	1d6c76e11f	audiodsp/x86: fix ff_vector_clip_int32_sse2 This version, which is the only one doing two processing cycles per loop iteration, computes the load/store indices incorrectly for the second cycle. CC: libav-stable@libav.org	9 years ago
Diego Biurrun	de452e5037	pixblockdsp: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.	9 years ago
Diego Biurrun	721d57e608	vp56: Separate VP5 and VP6 dsp initialization VP5 has no arch-specific optimizations (nor will it get some in the future), so it makes no sense to try to share dsp init code with VP6.	9 years ago
Diego Biurrun	3fd22538bc	prores: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "linesize" everywhere.	9 years ago
Diego Biurrun	f81be06cf6	cavs: Change type of stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	9 years ago

Geza Lore	cc602061ee	x86inc: Add debug symbols indicating sizes of compiled functions Some debuggers/profilers use this metadata to determine which function a given instruction is in; without it they get can confused by local labels (if you haven't stripped those). On the other hand, some tools are still confused even with this metadata. e.g. this fixes `gdb`, but not `perf`. Currently only implemented for ELF.

Janne Grunau	8563f98871	x86: use emms after ff_int32_to_float_fmul_scalar_sse Intel's Instruction Set Reference (as of September 2015) clearly states that cvtpi2ps switches to MMX state. Actual CPUs do not switch if the source is a memory location. The Instruction Set Reference from 1999 (Order Number 243191) describes this behaviour but all later versions I've seen have make no distinction whether MMX registers or memory is used as source. The documentation for the matching SSE2 instruction to convert to double (cvtpi2pd) was fixed (see the valgrind bug https://bugs.kde.org/show_bug.cgi?id=210264). It will take time to get a clarification and fixes in place. In the meantime it makes sense to change ff_int32_to_float_fmul_scalar_sse to be correct according to the documentation. The vast majority of users will have SSE2 so a change to the SSE version has little effect. Fixes fate-checkasm on x86 valgrind targets. Valgrind 'bug' reported as https://bugs.kde.org/show_bug.cgi?id=357059	9 years ago
