Rafaël Carré 45c7498f59 FS#11335 by me: make ARM assembly functions thumb-friendly 
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

arm.h Revert r25929. Test have shown that the assembler code is more than 50% faster than the C code both on ARM7TDMI (tested on PP5002 and PP5022) and on ARM1136JF-S (tested on Gigabeat S). If it is slower on ARM9*, it should be disabled for ARM9 only. 2010-05-10 19:05:25 +00:00

bitstream.c New FLAC decoder from the ffmpeg project 2005-10-26 12:35:58 +00:00
bitstream.h Remove all tabs within codec path. 2010-02-22 19:44:05 +00:00
coldfire.h Assembler optimised FLAC 24 bit handling routines for Coldfire based players. Decoding speed should be improved drastically. Haven't got so many 24 bit files myself, so let me know if something sounds off. 2006-10-25 00:59:38 +00:00
coldfire.S Updated our source code header to explicitly mention that we are GPL v2 or 2008-06-28 18:10:04 +00:00

decoder.h Added macros controlling what goes to IRAM on different targets. 2006-11-09 21:59:27 +00:00
golomb.h Remove all tabs within codec path. 2010-02-22 19:44:05 +00:00
libffmpegFLAC.make Submit FS#11381. Use -O2 for ffmpegFLAC on ARM targets. This will give reasonable speed-up (+3% on PP502x) for svn and major speed-up when switching to eabi tool chain (+9% on PP502x). Coldfire was tested to be faster when keeping -O1. 2010-06-09 06:21:28 +00:00
main.c Make open() posix compliant api-wise. A few calls (those with O_CREAT) need the additional optional mode parameter so add it. Impact for the core is almost zero, as open() is a wrapper macro for the real open function which doesn't take the variable parameter. 2010-05-06 17:35:13 +00:00
Makefile.test Make the standalone FLAC test program work again (compile with make -f Makefile.test). 2008-07-19 08:41:21 +00:00
