* avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara2014-08-04
| | | | | | | The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.

* fate: add informative cpu testJanne Grunau2014-08-04
| | | | | | | | libavutil/cpu-test prints raw and effective cpu flags to STDERR. Detected cpu flags can be useful for debugging fate errors. No comparison of the result against a expected result since that would require fate config specific references.

* arm: Detect 32 bit cpu features on ARMv8 when running on a 64 bit kernelMartin Storsjö2014-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | When running on a 64 bit kernel, /proc/cpuinfo lists different optional features than on 32 bit kernels (because some of them are mandatory in the 64 bit implemenations). The kernel does list the old features properly if they are queried via /proc/self/auxv though - however this file is not always readable (e.g. on most android systems). The getauxval function could also provide the same info as /proc/self/auxv even if this file isn't readable, but this function is not always available (and thus would need to be loaded with dlsym for compatibility with older android versions). The android cpufeatures library does this slightly differently, by assuming that these are available if the "CPU architecture" line is >= 8, see [1] for details. It has been suggested to include the old, non-optional features in /proc/cpuinfo as well, but that suggested patch never was merged. See [2] for the discussion around this suggestion.

* build: check if AS supports the '.func' directiveJanne Grunau2014-06-03
| | | | | Not supported by Clang's integrated assembler. Since it just adds debug information it can safely omitted.
* aarch64: use '#' for whole line asm commentsJanne Grunau2014-06-03
| | | | | | | Both gnu as and clang treat lines starting with '#' as comments if they aren't consumed by the C-style preprocessor. Using '//' does not work with clang since comments are removed before macro expansion.

* Remove all Blackfin architecture optimizationsDiego Biurrun2014-06-02
| | | | | | Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.

| | | | | | | | | | This fixes building in PIC mode with gas. The examples in the gas manual showed using a # here even though gas itself actually didn't support that syntax (and the gas test suite only tests it without the extra hash sign).
