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.

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.

libwavpack: put some lookup tables in iram, speedup of 8-10% on coldfire (h300).

make WavPack library check the extent of the block that it is parsing so that it cannot run into the next block; also enhance the metadata code to handle the case of files with non-audio blocks at the beginning (which can happen if the source WAV file has lots of RIFF data)

Rockbox as an application: Commit current Android port progress.

2010-08-02T20:34:47+00:00

General state is: Rockbox is usable (plays music, saves configuration, touchscreen works too).
Problems:
 - Playing music in the background (i.e. when switching to another app) doesn't work reliably, but I'm working on that now.
 - no cabbiev2 (only some preliminary files for it), no other default theme.
 - screen flickers sometimes if the updates are too frequent
 - no multi screen apk/package
 - strange behavior when a phone call comes in

The java files (and the eclipse project) resides in android/, which is also supposed to be the build folder.
I've put a small README in there for instructions. There are some steps needed after the make part, which are described there,
and which eclipse mostly handles. But there ought to be some script/makefile rules which do that instead in the future.

FS#11454 Tuning of codec compiler options

2010-07-18T19:05:53+00:00

Tested with h300 and sansa c200v1

h300 speedups:
a52: 2%
cook: 9-17%
aac: 0.5%
vorbis: 0.5%
wma: 6-12%

c200v1 speedups:
alac: 1.5%
wma 3-4%
wavpack 2%

FS#11335 by me: make ARM assembly functions thumb-friendly

2010-06-11T04:41:36+00:00

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

Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes).

2010-05-06T21:04:40+00:00

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657

Remove all tabs within codec path.
