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.

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

Use MEM_ALIGN_ATTR in libdemac instead of fixed alignment. Speeds up arm11 by ~6%.

workaround weird gcc behaviour

2010-09-07T14:58:10+00:00

it might a bug in the 4 years old gcc version, but __ASSEMBLER__ is not
defined when preprocessing .S files with -std=gnu99

libdemac: ARMv7 assembler optimisation for the filters, tested on Nokia N900. Speedup is 2.1x for -c5000 compared to the ARMv6 asm. Note that actually compiling it on device requires hand-assembling the 'vadd' and 'vsub' instructions due to a bug in binutils 2.18.50, and making the standalone decoder use it requires Makefile and demac_config.h hacks.

Make libdemac compile again on OSX x86 and x86_64 by replacing .rept with fancy preprocessor stuff.
