2013-10-28AVOptions: do not range check flag options.Anton Khirnov
It does not make sense in the vast majority of use cases, no currently defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything nontrivial, and many of those get it wrong (the "correct" range is INT_MIN to INT_MAX so that the builtin constant "all" works).

2013-10-23avstring-test: Mark pointer passed to av_free() as non-constDiego Biurrun
libavutil/avstring.c:278:9: warning: passing argument 1 of ‘av_free’ discards ‘const’ qualifier from pointer target type
2013-10-16mem: Make av_strdup allocate using av_reallocMartin Storsjö
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>

2013-10-14x86inc: Remove our FMA4 supportDerek Buitenhuis
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>
2013-10-14x86inc: Use VEX-encoded instructions in AVX functionsHenrik Gramner
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>
2013-10-09x86inc: Remove .rodata kludgesHenrik Gramner
The Mach-O bug was fixed in yasm 0.8.0 and we don't support versions that old anymore. 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: various minor backports from x264Jason Garrett-Glaser

2013-10-07x86inc: Utilize the shadow space on 64-bit WindowsHenrik Gramner
Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2013-10-07x86inc: Use SSE instead of SSE2 for copying dataHenrik Gramner

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.

2013-09-20msvc/icl: Use __declspec(deprecated)Alex Smith
Prior to this on msvc/icl there was no handling of deprecated functions and the deprecated warning was disabled. After enabling there are a number of warnings relating to the CRT and the use of the non-secure versions of several functions. Defining _CRT_SECURE_NO_WARNINGS silences these warnings.

2013-08-10libavutil: Make avpriv_open a library-internal function on msvcrtMartin Storsjö
Add one copy of the function into each of the libraries, similarly to what we do for log2_tab. When using static libs, only one copy of the file_open.o object file gets included, while when using shared libraries, each of them get a copy of its own. This fixes DLL builds with a statically linked C runtime, where each DLL effectively has got its own instance of the C runtime, where file descriptors can't be shared across runtimes. On systems not using msvcrt, the function is not duplicated. Signed-off-by: Martin Storsjö <martin@martin.st>

2013-08-10libavutil: Enable the MSVC DLL symbol loading workaround in shared builds as ↵Martin Storsjö
well This used to only be necessary in static builds (when using the dynamically linked C runtime), since the _imp prefixed symbols do exist when linking to the actual DLL. When building testprogs, however, the current library (e.g. libavutil for some of the testprogs) is linked statically. This fixes make fate on DLL builds when using the dynamically linked C runtime. Signed-off-by: Martin Storsjö <martin@martin.st>
2013-08-08file: Move win32 utf8->wchar open wrapper to libavutilMartin Storsjö
When libavformat was changed to use the new avpriv_open function in 51eb213d001, this silently bypassed the existing wrapper for win32. Move the win32 wrapper into libavutil/file.c to make sure it gets called everywhere (not just in the libavformat case). This makes sure that non-ascii file names gets opened properly (where file names internally are stored as utf8, but they get converted to wchar_t and opened with _wsopen).
