* build: miscellaneous cosmeticsDiego Biurrun2016-04-07
| | | | | | Restore alphabetical order in lists, break overly long lines, do some prettyprinting, add some explanatory section comments, group parts together that belong together logically.
* fft: Split MDCT bits off from FFTDiego Biurrun2016-03-01

* fft: x86: cosmetics: Drop silly comments, add comment, whitespaceDiego Biurrun2016-02-26
|
* x86: hevc: Fix linking with both yasm and optimizations disabledDiego Biurrun2016-02-23
| | | | | Some optimized functions reference optimized symbols, so the functions must be explicitly disabled when those symbols are unavailable.
* build: Add vc1dsp component for more fine-grained dependenciesDiego Biurrun2016-02-19

* v210: Use separate sample_factorsLuca Barbato2016-02-01
| | | | | | | 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.
* v210: Add avx2 version of the 10-bit line encoderJames Darnley2016-02-01
| | | | | | Around 25% faster than the ssse3 version. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* v210: Add avx2 version of the 8-bit line encoderJames Darnley2016-02-01
| | | | | | | Around 35% faster than the avx version. Signed-off-by: Henrik Gramner <henrik@gramner.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* x86inc: Add debug symbols indicating sizes of compiled functionsGeza Lore2016-01-23
| | | | | | | | | | | 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. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* x86: use emms after ff_int32_to_float_fmul_scalar_sseJanne Grunau2015-12-30
| | | | | | | | | | | | | | | | | | | | | 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
* x86: zero extend the 32-bit length in int32_to_float_fmul_scalar implicitlyJanne Grunau2015-12-29
| | | | This reverts commit 5dfe4edad63971d669ae456b0bc40ef9364cca80.
* dca: remove unused decode_hf function and quant_d tablesAlexandra Hájková2015-12-24
| | | | | They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.
* x86_64: int32_to_float_fmul_scalar sign extend integer lengthJanne Grunau2015-12-14

* lavc: Drop deprecated deinterlace moduleVittorio Giovara2015-08-28
| | | | Deprecated in 03/2013.
* x86inc: Drop SECTION_TEXT macroHenrik Gramner2015-08-11
| | | | | | | 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>
* x86inc: Support arbitrary stack alignmentsHenrik Gramner2015-08-11
| | | | | | | | 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>
* x86: dcadsp: Avoid SSE2 instructions in SSE functionsHenrik Gramner2015-08-11

* x86: dct: Disable dct32_float_sse on x86-64Henrik Gramner2015-08-02
| | | | | | | 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>

* x86: bswapdsp: Don't treat 32-bit integers as 64-bitHenrik Gramner2015-07-17
| | | | | | | | | 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. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* idctdsp: Add global function pointers for {add|put}_pixels_clamped functionsDiego Biurrun2014-09-02
| | | | | | These function pointers already existed in the ARM code. Adding them globally allows calls to the function pointers to access arch-optimized versions of the functions transparently.
