Diego Biurrun	01621202aa	build: miscellaneous cosmetics Restore alphabetical order in lists, break overly long lines, do some prettyprinting, add some explanatory section comments, group parts together that belong together logically.	9 years ago
Diego Biurrun	1a094af638	fft: Split MDCT bits off from FFT	9 years ago
Diego Biurrun	73ff983e8d	fft: x86: cosmetics: Drop silly comments, add comment, whitespace	9 years ago
Diego Biurrun	257b30af8e	x86: hevc: Fix linking with both yasm and optimizations disabled Some optimized functions reference optimized symbols, so the functions must be explicitly disabled when those symbols are unavailable.	9 years ago
Diego Biurrun	15a24614ae	build: Add vc1dsp component for more fine-grained dependencies	9 years ago
Luca Barbato	e280fe1329	v210: Use separate sample_factors The 10bit and the 8bit functions can now be implemented to process a different amount of samples. And while at it simplify a little the code.	9 years ago
James Darnley	15ec7aa417	v210: Add avx2 version of the 10-bit line encoder Around 25% faster than the ssse3 version. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
James Darnley	d29237e557	v210: Add avx2 version of the 8-bit line encoder Around 35% faster than the avx version. Signed-off-by: Henrik Gramner <henrik@gramner.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Luca Barbato	eafb05fcf3	v210: x86: Add the correct guards around the asm code Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	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.

Diego Biurrun	03ef89faf2	x86: build: Group all encoder objects together	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
Janne Grunau	f4f27e4cf1	x86: zero extend the 32-bit length in int32_to_float_fmul_scalar implicitly This reverts commit `5dfe4edad6`.	9 years ago
Alexandra Hájková	2008f76054	dca: remove unused decode_hf function and quant_d tables They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.	9 years ago
Janne Grunau	5dfe4edad6	x86_64: int32_to_float_fmul_scalar sign extend integer length	9 years ago

Vittorio Giovara	cad40a3833	lavc: Drop deprecated deinterlace module Deprecated in 03/2013.	9 years ago
Henrik Gramner	ab43beefab	x86inc: Drop SECTION_TEXT macro The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	9f1245eb96	x86inc: Support arbitrary stack alignments Change ALLOC_STACK to always align the stack before allocating stack space for consistency. Previously alignment would occur either before or after allocating stack space depending on whether manual alignment was required or not. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	4a53c758d2	x86: dcadsp: Avoid SSE2 instructions in SSE functions Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	ebaf571aca	x86: dct: Disable dct32_float_sse on x86-64 There is an SSE2 implementation so the SSE version is never used. The "SSE" version also happens to contain SSE2 instructions on x86-64. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago

Henrik Gramner	a344e5d094	x86: bswapdsp: Don't treat 32-bit integers as 64-bit The upper halves are not guaranteed to be zero in x86-64. Also use `test` instead of `and` when the result isn't used for anything other than as a branch condition, this allows some register moves to be eliminated.
