Gigabeat S: Reduce stalling in the ARMv6 IDCT. Also save one instruction per loop, and fix comments. Speeds up fullscreen video decoding by about 5% (excluding video output). Still not perfect...

Further ARMv6 imdct optimisation, ~5.5% speedup.

* Fix overlooked r12 usage possibility in mpegplayer ARM idct

2009-07-12T22:43:24+00:00

* ARM dualcore: Don't save r12 in switch_thread_core()

* ARM asm DSP and codec/plugin functions: Use r12 scratch register properly

2009-07-12T13:14:35+00:00

* Fix saving another unused reg in dsp code
* Use less regs in the generic ARM mpegplayer adding idct pure DC case
* Fix ARMv6 mpegplayer adding idct using an unsaved register in pure DC case

Faster idct for ARMv6. Overall mpegplayer speedup is quite minimal though.
