build system: completely autodetect target cpu architecture.

2012-03-28T21:02:39+00:00

The existing ARCH Makefile variable is exported to the C code as well.
Additionally the version (arm-only for now) is detected as well. This
allows to for complete autodetection, i.e. that optimized ASM is picked up
if determined by preprocessor (CPU_ARM, etc).

Building a sim/raaa on a arm host will now automatically generate a arm
optmized build like we have for native targets.

libmad: Get rid of some bad trickery with the stack pointer.

2012-01-21T17:39:19+00:00

Using the stack pointer for anything else than pointing to the
current stack can have in very bad effects, especially on hosted
platforms (e.g. when mixed with signals). Remove this at
very slight performance cost.

libmad: Fix section attrs for hosted platforms.

Submit FS#12142 by Sean Bartell with minor chnages by myself. Removes unused code and irrelevant files from libmad.

Redo r28026 so that all .S files get the ASSEMBLER define.

ARM9 optimized synth_full for libmad. Speeds up mp3 decoding by an even 2 MHz on all ARM9 and later devices. Note this is only optimized for arm9 (non-E), although it is faster on later devices. An arm9E/11 version will be needed for optimal performance on newer devices.

Force alignment of various data structures in libmad. Speeds up Gigabeat S decoding by about 1MHz.

Commit first part of FS#11235 by Buschel and I. Improves scheduling on arm9 for two filter macros in libmad that are almost never called. A larger speed up will be possible when the remaining ASM code is improved.
