* | avutil/crc: Dont limit CRC32 standard tablesJames Almer2013-06-01
| | | | | | | | | | | | | | | | | | Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or provided in case the user compiles with hardcoded tables) with only 257 elements. We're missing a considerable boost in performance by not making them with a size of 1024 elements instead. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | md5: optimize second round by using 4-operation form of G()Giorgio Vazzana2013-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4-operation form is preferred over 3-operation because it breaks a long dependency chain, thus allowing a superscalar processor to execute more operations in parallel.
