libmad: Get rid of some bad trickery with the stack pointer.

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

Using the stack pointer for anything else than pointing to the
current stack can have in very bad effects, especially on hosted
platforms (e.g. when mixed with signals). Remove this at
very slight performance cost.

ARM9 optimized synth_full for libmad. Speeds up mp3 decoding by an even 2 MHz on all ARM9 and later devices. Note this is only optimized for arm9 (non-E), although it is faster on later devices. An arm9E/11 version will be needed for optimal performance on newer devices.

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

Change naming of arm asm routines in libmad's synthesis to match their functionality.

Refacturate arm version of libmad's synthesis filter. Only two asm macros left, renamed asm-implementation for better clarity. No change in speed or precision.

* ARM asm DSP and codec/plugin functions: Use r12 scratch register properly

2009-07-12T13:14:35+00:00

* Fix saving another unused reg in dsp code
* Use less regs in the generic ARM mpegplayer adding idct pure DC case
* Fix ARMv6 mpegplayer adding idct using an unsaved register in pure DC case

Revert r14050 (apart from the non-related whitespace changes) and fix the S3C2440 (Gigabeat F/X) problems introduced by my r14041 commit in a slightly different way: Introduce a mad_iram.h file and centralise all IRAM-related decisions in there (similar to how Tremor does it). Now checks for CPU type (S3C2440) instead of target (TOSHIBA_GIGABEAT_F) and there is also a .ibss variable in syth_full_arm.S which shouldn't go in IRAM on S3C2440 targets. Closes FS#7500
