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.

FS#12231

2011-08-18T16:33:41+00:00

Centralize the selection of codec compilation flags to codec.make
to avoid having to duplicate the per cpu selection logic and the
build rule in the individual codec lib make files and make tweaking
easier.

The two special cases, libmad and libspeex were left alone.

I plan to introduce a var for arm generation so that appropriate flags
can be selected per generation as benchmarking results have shown that
different arm arches might have different optimal flags.

Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note:
* The old MDCT has been removed.
* Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs.
* I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib.

Fix #11897 - Multiple 'divide by zero' while playing particular APE on Clip+. Problem and solution observed and checked on Gigabeat S by myself. Fix submitted by Mikhail Titov resolves it. range_decode_short was declared as returing 'int short' rather than 'unsigned short' resulting in unwanted sign extension.

Switch coldfire builds over to new toolchain using gcc 4.5.2 and binutils 2.20.1

Retune codec compiler optimizations with new compiler. Overall speedup with aac and flac getting big speedups.
