build system: completely autodetect target cpu architecture.

2012-03-28T21:02:39+00:00

The existing ARCH Makefile variable is exported to the C code as well.
Additionally the version (arm-only for now) is detected as well. This
allows to for complete autodetection, i.e. that optimized ASM is picked up
if determined by preprocessor (CPU_ARM, etc).

Building a sim/raaa on a arm host will now automatically generate a arm
optmized build like we have for native targets.

tlsf: move to /lib (it's also used by plugins).

Move supprt-arm.S to separate library.

2012-01-21T17:39:19+00:00

Core, codecs and plugins link it separately so this gets rid of SOURCES trickery.
Don't build it for hosted targets.

codeclib/libtremor: Clean up duplication of inline funcs, constify the ones in codeclib and copy over the slightly faster MULT31_SHIFT15 from tremor for cf.

codeclib: more cf asm for the mdct, saves ~0.7MHz decoding vorbis on h300.

codeclib: further tweaks to the cf fft asm for a small speedup.

codeclib: tweak coldfire mdct asm a bit more, flip usage of mac/msac instead of explicit negation, changes output slightly but is as close to the c version as before. Gives about 0.4MHz speedup of vorbis on cf.

codeclib: coldfire asm for the TRANSFORM* functions in the fft and a little for the mdct, speeds up codecs using the codeclib mdct 0.5-1.5MHz on h300.

Submit FS#12258. Do not use '-ffunction-sections' and '-fdata-sections' when compiling. Fixes compiler warnings for mingw and cygwin simulatior builds.
