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.

Refactor alac decoder as preparation for upcoming m4a changes. The alac decoder does not need to use get_sample_info() to gather frame size or the number of consumed bytes.

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.

FS #10690: Add support for 24 bit ALAC files based on libalac 0.2.0

2010-02-03T00:37:24+00:00

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24475 a1c6a512-1295-4272-9138-f99709370657

Extend av_log2 in codeclib into a generic for scanning for set bits, which can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic.
