c0951d95b3 Resort operands in mul/smull/mla/smlal to use D[] as second multiplication operand. Additionally do not pre-scale D[] for the 64 Bit precision synthesizer. Through this the 64 Bit multiplication is speed up by 1.5MHz without loss of precision.

f52696ef8a Correct DSP_SET_SAMPLE_DEPTH to 29 for mpc (18.14 fixed point samples). Higher precision for fast 32x32=32 multiplication in dewindowing part of synthesis filter.

cc11e9466a Further changes in mpc buffered seek. Remove magical number and replace it with a better commented #define. Use shift and bit mask instead of division and modulo operations when using the seek buffer. Saves some binary size for the codec.

bc97952134 libmad: PP5002 does in fact profit more from -O2 than PP502x, so use it for all targets. The previous check was half-baked (excluded iPod 3rd Gen only, but 1st/2nd Gen are also PP5002).

6a74a5dd3b Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer of 8192 entries is used. The seeking precision is adapted to the length of the file (e.g. 26ms for files <=3.5min and 0.4s for files ~60min).

05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

b2fa99b4dd Vorbis codec: Only try to put the ARM assembler optimised MDCT in IRAM if the target uses IRAM. This fixes the code for gigabeat, but it is kept disabled for gigabeat because the C code is actually slightly faster (~0.5%).

ef1f7d3bf9 SPC Codec: Ensure no crash occurs on load failure which could cause emulation to be run without a program loaded on dual core (DSP wasn't initialized yet). The load failures come from core buffering not having the atomic audio file fully loaded before the codec requests the buffer (it gets as many bytes as can be provided) which IMHO isn't very atomic :). Changes in thread execution order after dumping spinlocks for general use simply revealed the buffering race condition. No fix for that will be hacked into the codec itself but should be fixed in the core. Add my copyright to files I had a significant part in developing per request of Adam Gashlin.

1df1e7b0c7 Remove unused conf_preseek from buffering.c and all of its accountraments. This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements. It may also belong in buffering not playback, haven't decided for sure

8431c08b7d QMF filter memory doesn't need to be 32 bits, so convert it to 16 bits. Alter assembler code to reflect this. Also do a small optimization in the reverse block copy of the qmf_synth() Coldfire assembler.

35f23267bf Further optimised the filter vector math assembly for coldfire, and added assembly filter vector math for ARM. Both make use of the fact that the first argument of the vector functions is longword aligned. * The ARM version is tailored for ARM7TDMI, and would slow down arm9 or higher. Introduced a new CPU_ macro for ARM7TDMI. Speedup for coldfire: -c3000 104%->109%, -c4000 43%->46%, -c5000 1.7%->2.0%. Speedup for PP502x: -c2000 66%->75%, -c3000 37%->48%, -c4000 11%->18%, -c5000 2.5%->3.7%

3ea3caf341 * Flip argument order for scalarproduct() so that the first argument is always 32 bit aligned, like it is already the case for vector_add() and vector_sub(), for upcoming optimisations. * Un-inline the apply_filter functions for better cache utilisation.

86a999c478 Change decoder struct dynamic array members to static arrays sized based on current maximums.
