* 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

* Commit fix by Tom Ross in FS#7488 wherein a silly mistake noise coding ↵Michael Giacomelli2008-12-20

* Use cookies for thread identification instead of pointers directly which ↵Michael Sevakis2008-12-10
| | | | | | gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19377 a1c6a512-1295-4272-9138-f99709370657
* Assembler optimised mono predictor for ARM. Speedup for -c1000 mono is ~5% ↵Jens Arnold2008-12-09

* Implement mono predictor in assembler for coldfire, yielding a ~6% speedup ↵Jens Arnold2008-12-02
| | | | | | for mono -c1000. Apply ideas gained from it back to the stereo predictor, saving 4 instructions. No speed increase for stereo, probably due to cache aliasing effects. * 80-column police. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19296 a1c6a512-1295-4272-9138-f99709370657

* Speed up the predictor a little by using ldrd/strd on ARMv5+. This required ↵Jens Arnold2008-11-27
| | | | | | shuffling around the register allocation somewhat. Performance on ARMv4 is unaffected. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19248 a1c6a512-1295-4272-9138-f99709370657

* 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
* Branch optimisation in both C (giving hints to gcc - verified using ↵Jens Arnold2008-11-24
| | | | | | -fprofile-arcs and gcov) and asm files. Biggest effect on coldfire (-c1000: +8%, -c2000: +5%), but ARM also profits a bit (less than 1% on ARM7TDMI, around 1% on ARM1136). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19199 a1c6a512-1295-4272-9138-f99709370657
