* Make the codecs use more IRAM on S5L870x, as we have plenty of it.Michael Sparmann2009-11-09

* Don't use ldrd/strd on ARMv5 since not all revisions support them and the ↵Jens Arnold2009-07-17
| | | | | | gain from using them is minimal (basically code size only). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21916 a1c6a512-1295-4272-9138-f99709370657

* Stop hiding errors by redirecting stderr to /dev/null. If we really need to ↵Daniel Stenberg2009-02-23
| | | | | | 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

* Slight speedup for the APE filters. Most noticeable on coldfire (+3.5% for ↵Jens Arnold2008-12-22
| | | | | | -c2000), but also helps on the arm targets (+0.9% for -c2000 on PP5002). This transformation is oveflow safe, as absres < 2^24 is guaranteed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19556 a1c6a512-1295-4272-9138-f99709370657

* Assembler optimised mono predictor for ARM. Speedup for -c1000 mono is ~5% ↵Jens Arnold2008-12-09
| | | | | | on PP, ~8% on Gigabeat S (less for higher compression levels). Also fix some overlooked comments in the stereo predictor. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19375 a1c6a512-1295-4272-9138-f99709370657
* Implement mono predictor in assembler for coldfire, yielding a ~6% speedup ↵Jens Arnold2008-12-02
| | | | | | for mono -c1000. Apply ideas gained from it back to the stereo predictor, saving 4 instructions. No speed increase for stereo, probably due to cache aliasing effects. * 80-column police. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19296 a1c6a512-1295-4272-9138-f99709370657
* Shuffling around register allocation allows to keep decoded0 and decoded1 in ↵Jens Arnold2008-12-01
| | | | | | registers, for a slight speedup. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19287 a1c6a512-1295-4272-9138-f99709370657

* Resurrect the ARM7 16-bit packed vector addition/subtraction for ARMv5, ↵Jens Arnold2008-11-28
| | | | | | giving a nice speedup for the higher compression levels (tested on Cowon D2). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19260 a1c6a512-1295-4272-9138-f99709370657
* On ARM9TDMI (e.g. Gigabeat F) it's faster to use a ldr/str pair than ↵Jens Arnold2008-11-27
| | | | | | add+ldmia/stmia for 2 registers. On ARM7TDMI a str pair is equally fast, so go for the simpler macro and use it for all ARMv4. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19250 a1c6a512-1295-4272-9138-f99709370657
* Speed up the predictor a little by using ldrd/strd on ARMv5+. This required ↵Jens Arnold2008-11-27
| | | | | | shuffling around the register allocation somewhat. Performance on ARMv4 is unaffected. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19248 a1c6a512-1295-4272-9138-f99709370657
* Get rid of unused return values, except the one from decode_chunk() which ↵Jens Arnold2008-11-26
| | | | | | will be used in the dual core split. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19236 a1c6a512-1295-4272-9138-f99709370657
* Added 'keywords' and 'eol-style' properties.Björn Stenberg2008-11-25
| | | | git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19218 a1c6a512-1295-4272-9138-f99709370657
* Reorder instructions to avoid pipeline stalls on ARMv6 wherever possible ↵Jens Arnold2008-11-24
| | | | | | (sometimes using different registers to allow this). Speeds up the predictor by almost 20% on ARMv6 (overall speedup for -c1000 is 5%), and might also help a bit on ARMv5. ARMv4 speed is unaffected. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19210 a1c6a512-1295-4272-9138-f99709370657
* Branch optimisation in both C (giving hints to gcc - verified using ↵Jens Arnold2008-11-24
| | | | | | -fprofile-arcs and gcov) and asm files. Biggest effect on coldfire (-c1000: +8%, -c2000: +5%), but ARM also profits a bit (less than 1% on ARM7TDMI, around 1% on ARM1136). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19199 a1c6a512-1295-4272-9138-f99709370657
* Tweak the ARMv6 filter assembly a bit further.Jens Arnold2008-11-24
| | | | git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19198 a1c6a512-1295-4272-9138-f99709370657

* New makefile solution: A single invocation of 'make' to build the entire ↵Björn Stenberg2008-11-20
| | | | | | | | | tree. Fully controlled dependencies give faster and more correct recompiles. Many #include lines adjusted to conform to the new standards. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19146 a1c6a512-1295-4272-9138-f99709370657
* Several tweaks and cleanups: * Use .rept instead of repeated macros for ↵Jens Arnold2008-11-19
| | | | | | repeating blocks. * Use MUL (variant) instead of MLA (variant) in the first step of the ARM scalarproduct() if there's no loop. * Unroll ARM assembler functions to 32 where not already done, plus the generic scalarproduct(). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19144 a1c6a512-1295-4272-9138-f99709370657
* Compile-time choice between 16 bit and 32 bit integers for the filters. 32 ↵Jens Arnold2008-11-19
| | | | | | bit filters are faster on ARMv4 (with assembler code), so use them there. Nice speedup on PP and Gigabeat F/X. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19140 a1c6a512-1295-4272-9138-f99709370657

* Further optimised (vs. libgcc) unsigned 32 bit division for ARMv4 (based on ↵Jens Arnold2008-11-05
| | | | | | the ARMv5(+) version from libgcc), in IRAM on PP for better performance on PP5002, and put into the codeclib for possible reuse. APE -c1000 is now usable on both PP502x and PP5002 (~138% realtime, they're on par now). Gigabeat F/X should also see an APE speedup. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19009 a1c6a512-1295-4272-9138-f99709370657
