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

2010-05-14Fix FS#11261 (slow seek forward in mpc files). Since the introduction of the ↵Andree Buschmann
sv8 library mpc did not use efficient buffering when seeking forward. With this change the implementation will not flush the buffer on each frame but will keep the already buffered data as long as possible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26032 a1c6a512-1295-4272-9138-f99709370657

2010-03-07Major change to musepack decoder: Import v1.3.0 (r458 from svn.musepack.net) ↵Andree Buschmann
to rockbox. Several adaptions in the musepack decoder were made to get the library work and perform fast under rockbox on several targets. With this change mpc sv8 is supported, including seek, replay gain and metadata support. The decoding speed is a 1-4% lower than the last implementation. Reason for this is main restructuring in the bitstream demuxer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25056 a1c6a512-1295-4272-9138-f99709370657

2009-02-23Stop hiding errors by redirecting stderr to /dev/null. If we really need to ↵Daniel Stenberg
do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20090 a1c6a512-1295-4272-9138-f99709370657

2008-06-14Resort operands in mul/smull/mla/smlal to use D[] as second multiplication ↵Andree Buschmann
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17719 a1c6a512-1295-4272-9138-f99709370657

2008-06-04Further changes in mpc buffered seek. Remove magical number and replace it ↵Andree Buschmann
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17686 a1c6a512-1295-4272-9138-f99709370657

2008-05-22Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer ↵Andree Buschmann
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). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17604 a1c6a512-1295-4272-9138-f99709370657
2008-05-19Musepack seek hotfix. Do not dynamically allocate seek buffer but use a ↵Andree Buschmann
buffer of constant size (~28.5min). Files larger than this will still not seek properly. Some additional rework has to be done for the seek buffer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17584 a1c6a512-1295-4272-9138-f99709370657

2008-05-14Musepack performance optimization for PP5022/PP5024/MCF5250 targets. Use ↵Andree Buschmann
IRAM for internal sample buffers and lookup tables. Speeds up decoding by ~7% on PP5022/PP5024 (Sansa: c200, e200 + iPod mini2G, nano, video) and by ~27% on MCF5250 (iaudio m5, x5). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17507 a1c6a512-1295-4272-9138-f99709370657

2008-05-10Some changes for musepack: Disable SV4-SV6 support (I guess I am the only ↵Andree Buschmann
