* avcodec/bitstream: replace qsort with AV_QSORTGanesh Ajjanagadde2015-10-18
| | | | | | | | | | | | | | | | | | | | | | | Commit 3a0a2f33a6c955823fa4fb12c0b49cd29a496659 claims large performance advantages for AV_QSORT over libc's qsort. The reason is that I suspect that libc's qsort (at least on non LTO builds, like the typical FFmpeg config) can't inline the comparison callback: https://stackoverflow.com/questions/5290695/is-there-any-way-a-c-c-compiler-can-inline-a-c-callback-function. AV_QSORT has two things going for it: 1. The guaranteed inlining of qsort itself. This yields a negligible boost that may be ignored. 2. The more serious possibility of potentially allowing the comparison function to be inlined - this is likely responsible for the large boosts reported. There is a comment explaining that this is a place that could use some performance improvement. Thus AV_QSORT is used to achieve that. Benchmarks deemed unnecessary due to existing claims about AV_QSORT. Tested with FATE.
