2011-12-04Collect the 16-bit signed range sample clipping routines scattered about, ↵Michael Sevakis
which can be optimized on armv6 and create firmware/export/dsp-util.h (for lack of better place right now). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31142 a1c6a512-1295-4272-9138-f99709370657
2011-08-31Get rid of strict aliasing warnings for ARMv6 spc_dsp.c. Just do load in asm ↵Michael Sevakis
block instead. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30396 a1c6a512-1295-4272-9138-f99709370657
2011-08-18FS#12231Nils Wallménius
Centralize the selection of codec compilation flags to codec.make to avoid having to duplicate the per cpu selection logic and the build rule in the individual codec lib make files and make tweaking easier. The two special cases, libmad and libspeex were left alone. I plan to introduce a var for arm generation so that appropriate flags can be selected per generation as benchmarking results have shown that different arm arches might have different optimal flags. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30330 a1c6a512-1295-4272-9138-f99709370657
2011-06-24SPC Codec: Restore correct FIR buffer alignment when an address mask is ↵Michael Sevakis
used. It must be FIR_BUF_ALIGN. Fix Coldfire assembly constraint where an input parameter was also being written. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30063 a1c6a512-1295-4272-9138-f99709370657

2011-05-15FS#12113: Optimize IRAM configuration for SPC. Performance increases by 5-6% ↵Andree Buschmann
on PP5022, PP5024 and S5L870x. No change of performance on Coldfire, PP5002 and PP5020. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29887 a1c6a512-1295-4272-9138-f99709370657
2011-01-19SPC Codec: AS3525 targets should be fast enough for realtime BRR decode and ↵Michael Sevakis
echo. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29089 a1c6a512-1295-4272-9138-f99709370657
2010-12-23SPC Codec: Was broken on ARMv6 since EABI switch and somehow I failed to ↵Michael Sevakis
notice in the first place (and so did eveyone else it seems :). Some early-clobber constraints were needed on inline assemebly operands. In some places, they aren't necessary where they were used, so remove those. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28880 a1c6a512-1295-4272-9138-f99709370657
2010-06-21Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with ↵Thomas Martitz
#if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR). The new define is to (de-)select code to compile on hosted platforms generally. Should be no functional change to targets or the simulator. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27019 a1c6a512-1295-4272-9138-f99709370657
2010-06-11Configure Gigabeat S with EABI compiler by default. Implement the INIT ↵Michael Sevakis
section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26779 a1c6a512-1295-4272-9138-f99709370657
2010-06-04SPC codec: The inline asm 'memory' clobbers should be unneeded since the ASM ↵Michael Sevakis
either does not modify memory (only loads values), or it modifies things only other ASM blocks deal with and the operand constraints mark them as in/out/both. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26538 a1c6a512-1295-4272-9138-f99709370657

2010-05-06Make open() posix compliant api-wise. A few calls (those with O_CREAT) need ↵Thomas Martitz
the additional optional mode parameter so add it. Impact for the core is almost zero, as open() is a wrapper macro for the real open function which doesn't take the variable parameter. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25844 a1c6a512-1295-4272-9138-f99709370657
2010-05-02Do some SPC codec optimizing for ARMv6 (as a training exercise), tweak ↵Michael Sevakis
realtime BRR for all CPU that use it, add Gaussian ASM optimization for all ARM that can use it. Add some LIKELY/UNLIKELY branch hints. On Gigabeat-S gives +22% speedup. For Gigabeat F, about +5% speedup. For less-powerful players, no real change aside possibly from branch hints. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25771 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

2008-11-20New makefile solution: A single invocation of 'make' to build the entire ↵Björn Stenberg
