[FFmpeg-devel] [PATCH 2/2] lavc/pcm_tablegen: always generate tables at runtime.

Previous commit has sped up pcm_tablegen slightly, and table generation of the alaw and mulaw tables is ~ 20k cycles. Thus, these tables can always be generated at runtime. Tested with/without --enable-hardcoded-tables. Signed-off-by: Ganesh Ajjanagadde ---

[FFmpeg-devel] [PATCH 1/2] lavc/pcm_tablegen: slight speedup of table generation

This gets rid of some branches to speed up table generation slightly (impact higher on mulaw than alaw). Tables are identical to before, tested with FATE. Sample benchmark (Haswell, GNU/Linux+gcc): old: 313494 decicycles in build_alaw_table,4094 runs, 2 skips 315959 decicycles in
