Christophe Gisquet	9630b3fc06	x86: lossless audio: SSE4 madd 32bits The unique user so far is wmalossless 24bits. The few samples tested show an order of 8, so more unrolling or an avx2 version do not make sense.

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.

Michael Niedermayer	da6f34516b	avcodec/x86/fmtconvert: Add emms to int32_to_float_fmul_array8_sse() this should fix checkasm on x86_64-archlinux-gcc-valgrind Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
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
