* 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.

* aarch64: Use the correct syntax for relocationsMartin Storsjö2014-05-29
| | | | | | | | | | 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).

* replaygain: correctly parse peak valuesAlessandro Ghedini2014-04-04
| | | | | | | | | | | | | | | According to the ReplayGain spec, the peak amplitude may overflow and may result in peak amplitude values greater than 1.0 with psychoacoustically coded audio, such as MP3. Fully compliant decoders must allow peak overflows. Additionally, having peak values in the 0<->UINT32_MAX scale makes it more difficult for applications to actually use the peak values (e.g. when implementing clipping prevention) since values have to be rescaled down. This patch corrects the peak parsing by removing the rescaling of the decoded values between 0 and UINT32_MAX and the 1.0 upper limit. Signed-off-by: Anton Khirnov <anton@khirnov.net>
