Ganesh Ajjanagadde	b492fbcc6e	lavc/dsd_tablegen: always generate tables at runtime ... Commit b272c3a5aa has sped up dsd_tablegen, and now table generation takes ~ 40k cycles. Thus, these tables can always be generated at runtime. Tested with/without --enable-hardcoded-tables. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	2015-12-30 20:37:13 -08:00
Ganesh Ajjanagadde	b272c3a5aa	lavc/dsd_tablegen: speed up table generation ... Tables are bit identical. Sample benchmark (Haswell, GNU/Linux+gcc): old: 814485 decicycles in dsd_ctables_tableinit, 512 runs, 0 skips new: 356808 decicycles in dsd_ctable_tableinit, 512 runs, 0 skips Binary size should essentially be identical, and is in fact identical on the configuration I tested on.
