2011-08-18FS#12231Nils Wallménius
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30330 a1c6a512-1295-4272-9138-f99709370657

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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29945 a1c6a512-1295-4272-9138-f99709370657

2010-11-17ffmpeg flac does actually support up to 192k sample rates, and my test file ↵Michael Giacomelli
seems to decode fine, so lets enable it. Note that using 192khz is over 6 times slower then 44.1khz on my test file, so I recommend sticking to more reasonable bitrates. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28609 a1c6a512-1295-4272-9138-f99709370657

ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code.

We can't pop into pc on ARMv4t when using thumb: the T bit won't be modified if we are returning to a thumb function Code running on ARMv4t should use the new ldrpc / ldmpc macros instead of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc} No modification on pure ARM builds and ARMv5+ Note: USE_THUMB is currently never defined, no targets can currently be built with -mthumb, see FS#6734 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26756 a1c6a512-1295-4272-9138-f99709370657
2010-06-09Submit FS#11381. Use -O2 for ffmpegFLAC on ARM targets. This will give ↵Andree Buschmann
