* Revert "Do schur_div with a direct 64 bit division instead of a loop on x86"Martin Storsjo2012-09-141-10/+0
| | | | | | | | | This reverts commit 923f3e95f3e332d26f03cf6782f0ab61596ceef2. The optimized version differed from the original in a few cases (in some cases where the return value turned out to be negative while the original implementation returned a positive value), so revert it for now until it has been analyzed completely.

* Use __builtin_clz instead of default implementation of fixnormz on GCCJakub Stachowski2012-08-141-0/+12
| | | | | | | | | | | | The library contains architecture specific versions of the clz functions for arm and mips, but the fallback C version for other architectures is pretty slow. By using __builtin_clz on GCC (available since GCC 3.4), we get a significant (20-40 %) speedup of the total running time on x86. Speed difference: 5.1 s instead of 8.6 s for AAC-LC 128 kbit/s and 3.8 s instead of 4.9 s for HE-AACv2 32 kbit/s, on an i7.
