* Slight speedup for the APE filters. Most noticeable on coldfire (+3.5% for ↵Jens Arnold2008-12-22
| | | | | | -c2000), but also helps on the arm targets (+0.9% for -c2000 on PP5002). This transformation is oveflow safe, as absres < 2^24 is guaranteed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19556 a1c6a512-1295-4272-9138-f99709370657

* Correctly implement remaining portions of ffmpeg's r8627 that I'd forgotten ↵Michael Giacomelli2008-12-20

* Use cookies for thread identification instead of pointers directly which ↵Michael Sevakis2008-12-10

* Reorder instructions to avoid pipeline stalls on ARMv6 wherever possible ↵Jens Arnold2008-11-24
| | | | | | (sometimes using different registers to allow this). Speeds up the predictor by almost 20% on ARMv6 (overall speedup for -c1000 is 5%), and might also help a bit on ARMv5. ARMv4 speed is unaffected. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19210 a1c6a512-1295-4272-9138-f99709370657
