Vittorio Giovara	0c4468dc18	stereo3d: Add API to get name from value or value from name Use it in av_dump_format() instead of a huge switch case.	9 years ago
Anton Khirnov	c46db38cde	hwcontext: add a dxva2 implementation	9 years ago
Anton Mitrofanov	2fb1d17a5a	x86inc: Enable AVX emulation in additional cases Allows emulation to work when dst is equal to src2 as long as the instruction is commutative, e.g. `addps m0, m1, m0`. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Mitrofanov	300fb0df84	x86inc: Improve handling of %ifid with multi-token parameters The yasm/nasm preprocessor only checks the first token, which means that parameters such as `dword [rax]` are treated as identifiers, which is generally not what we want. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Mitrofanov	8d02579fae	x86inc: Fix AVX emulation of some instructions Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	ba3eb745cc	x86inc: Fix AVX emulation of scalar float instructions Those instructions are not commutative since they only change the first element in the vector and leave the rest unmodified. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago

Thomas Guillem	785bfb1d7b	pixfmt: fix wrong comment The h264/hevc Annex E colour primaries table says that AVCOL_SPC_SMPTE170M is similar than AVCOL_SPC_SMPTE240M. These two values are not similar than AVCOL_SPC_BT470BG. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago

Vittorio Giovara	1546a41ada	pixdesc: Drop unneeded deprecation warning guards	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. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	002c47798d	x86inc: Avoid creating unnecessary local labels The REP_RET workaround is only needed on old AMD cpus, and the labels clutter up the symbol table and confuse debugging/profiling tools, so use EQU to create SHN_ABS symbols instead of creating local labels. Furthermore, skip the workaround completely in functions that definitely won't run on such cpus. Note that EQU is just creating a local label when using nasm instead of yasm. This is probably a bug, but at least it doesn't break anything. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	fd6ecac38e	x86inc: Simplify AUTO_REP_RET cpuflags is never undefined any more, it's set to 0 instead. Also fix an incorrect comment. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	5ca8e195e5	x86inc: Use more consistent indentation Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	91ed050f42	x86inc: Preserve arguments when allocating stack space When allocating stack space with a larger alignment than the known stack alignment a temporary register is used for storing the stack pointer. Ensure that this isn't one of the registers used for passing arguments. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Henrik Gramner	715eb7ca24	x86inc: Improve FMA instruction handling * Correctly handle FMA instructions with memory operands. * Print a warning if FMA instructions are used without the correct cpuflag. * Simplify the instantiation code. * Clarify documentation. Only the last operand in FMA3 instructions can be a memory operand. When converting FMA4 instructions to FMA3 instructions we can utilize the fact that multiply is a commutative operation and reorder operands if necessary to ensure that a memory operand is used only as the last operand.

Henrik Gramner	f60f06d989	x86inc: Be more verbose in assertion failures Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
