Rafaël Carré	c0bd4173aa	Make sure files which aren't windows-specific use \n line endings only ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26893 a1c6a512-1295-4272-9138-f99709370657	2010-06-17 16:59:51 +00:00
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 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26756 a1c6a512-1295-4272-9138-f99709370657	2010-06-11 04:41:36 +00:00
Andree Buschmann	35024bd54e	Speed up atrac codec for ARM through simple loop unrolling. Saves 9 MHz on PP5022 (14% speed up). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24637 a1c6a512-1295-4272-9138-f99709370657	2010-02-13 22:01:24 +00:00
Bertrik Sikken	6fef14bd16	Set svn:keywords property on .c and .h files that didn't already have it. Correct svn:executable property on some files. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24165 a1c6a512-1295-4272-9138-f99709370657	2010-01-03 14:28:09 +00:00
Andree Buschmann	f4774bf5bf	Submit interim version of FS#10565. Performance optimization of atrac3 decoder for ARM. Introduce ASM routines for multiplications and two synthesis loops, refactured parts of synthesis and windowing. Speeds up decoding by a factor of 2.4 on PP502x. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22548 a1c6a512-1295-4272-9138-f99709370657	2009-08-29 19:44:27 +00:00
