2013-10-17lavu/opt: add AV_OPT_TYPE_CHANNEL_LAYOUT and handler functionsStefano Sabatini
The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify channel layouts using the format accepted by av_get_channel_layout().
2013-10-17lavu/channel_layout: change av_get_channel_layout() behavior at the next bumpStefano Sabatini
The new syntax is preferred since it allows backward syntax compatibility with libswr when switching to the new option handling code with AV_OPT_TYPE_CHANNEL_LAYOUT. With the new parser the string: 1234 is interpreted as a channel layout mask, rather than as a number of channels, and thus it's compatible with the current way to set a channel layout as an integer (e.g. for the icl and ocl options) making use of integer option values. ff_get_channel_layout() with compat=0 will be used in the AV_OPT_TYPE_CHANNEL handler code. The user is encouraged to switch to the new forward compatible syntax, which requires to put a trailing "c" when specifying a layout as a number of channels.
2013-10-17lavu/opt.h: fix grammar typo in av_opt_get* doxyStefano Sabatini
2013-10-17lavu/opt-test: use automatic set and free handlersStefano Sabatini
In particular, do not set default string value by hand and use av_opt_free() to free context.

This makes sure that pointers from av_strdup are reallocable, which is used in av_dict_set if the AV_DICT_APPEND flag is set. Nothing should rely on pointers from av_strdup being aligned. Signed-off-by: Martin Storsjö <martin@martin.st>

This is so we can sync to x264's version of FMA4 support. This partialy reverts commit 79687079a97a039c325ab79d7a95920d800b791f. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

Automatically use VEX-encoding in AVX/AVX2/XOP/FMA3/FMA4 functions for all instructions that exists in a VEX-encoded version. This change makes it easier to extend existing code to use AVX2. Also add support for AVX emulation of a few instructions that were missing before. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2013-10-07x86inc: remove misaligned cpu flagHenrik Gramner
Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2013-10-07x86inc: activate REP_RET automaticallyLoren Merritt
Now RET checks whether it immediately follows a branch, so the programmer dosen't have to keep track of that condition. REP_RET is still needed manually when it's a branch target, but that's much rarer. The implementation involves lots of spurious labels, but that's OK because we strip them.
