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.

Use more IRAM on S5L870x to speed up wmapro by ~2%.

Fix nearly all residual 'variable set but not used' warnings reported from GCC 4.6.0.

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

2011-01-12T22:28:43+00:00

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

Using icode attribute for S5L870x is faster on some codecs. Speed up for mpc is ~3%, for aac ~1%.

Another minor ARM speedup for libwmapro. Drop lsb of multiplication result in fixmul31(). The difference to current implementation is +/-1 in the output signal. Same routines are used for other codecs and in the codec lib as well.

Minor of libwmapro on ARM. Swap operands for fixmul31, is 1% faster.

Remove the comment about Coldfire asm. The current code (using fixmul16 macros) is fast enough; even faster than an equivalent CF asm version, as pointed out by Nils Wallménius.

libwmapro: remove coldfire fixmul24 as it is both incorrect and unused, fix fixmul 31 comment.
