2011-01-12Switch coldfire builds over to new toolchain using gcc 4.5.2 and binutils 2.20.1Nils Wallménius
Retune codec compiler optimizations with new compiler. Overall speedup with aac and flac getting big speedups. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29042 a1c6a512-1295-4272-9138-f99709370657
2010-12-27Redo r28026 so that all .S files get the __ASSEMBLER__ define.Thomas Martitz

2010-08-27Use system headers a bit more: use host's fcntl.h for O_RDONLY etc.Thomas Martitz
Removes the need to fix up those in the simulator. Also work around some posix-mingw incompatibilities (e.g. getcwd()). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27904 a1c6a512-1295-4272-9138-f99709370657
2010-07-12Tune compiler optimizations for libtta, gives a speedup of 1.1MHz on h300 ↵Nils Wallménius
and 0.4MHz on c200v1. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27405 a1c6a512-1295-4272-9138-f99709370657
2010-07-12Coldfire assembler implementation of hybrid_filter for libtta. Speeds up ↵Nils Wallménius
decoding on h300 by 4.2MHz. Set svn properties. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27404 a1c6a512-1295-4272-9138-f99709370657
2010-07-12Use more iram in the tta lib, speeds up decoding by 47MHz on h300 (mcf5249) ↵Nils Wallménius
and 2.7MHz on c200v1 (pp5024) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27403 a1c6a512-1295-4272-9138-f99709370657
2010-07-03We already build with -fomit-frame-pointer so there's no need to specify ↵Nils Wallménius
that again. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27255 a1c6a512-1295-4272-9138-f99709370657
2010-06-11FS#11335 by me: make ARM assembly functions thumb-friendlyRafaël Carré
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

2010-05-13Put decoder array into IRAM. Improves Coldfire (h300) performance 218MHz ↵Michael Giacomelli
->102.84 MHz. Should be realtime on all CF targets. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25998 a1c6a512-1295-4272-9138-f99709370657
2010-05-13add True Audio (TTA) codecYoshihisa Uchida
decoding speed iPod video ~153% But in some players, the decoding speed is not enough. (e.g., H180 52.4% (thanks amiconn), H300 55.09% (thanks n1s)) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25994 a1c6a512-1295-4272-9138-f99709370657
