46507d29b4 FS#12113: Optimize IRAM configuration for SPC. Performance increases by 5-6% on PP5022, PP5024 and S5L870x. No change of performance on Coldfire, PP5002 and PP5020.

d1ff237798 SPC Codec: AS3525 targets should be fast enough for realtime BRR decode and echo.

6e4e5ea757 SPC Codec: Was broken on ARMv6 since EABI switch and somehow I failed to 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.

35e8b1429a Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #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.

60f843bf18 Configure Gigabeat S with EABI compiler by default. Implement the INIT 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.

06a98b15bc SPC codec: The inline asm 'memory' clobbers should be unneeded since the ASM 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.

0a1d7c28b7 Make open() posix compliant api-wise. A few calls (those with O_CREAT) need 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.

9f157ad584 Do some SPC codec optimizing for ARMv6 (as a training exercise), tweak 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.

13f08d70fd Enable strict aliasing optimizations for codecs on gcc versions >= 4.0, fix alising violations that this uncovered, gives small speedups for most codecs, FS#10801

738824ccdd Might as well enable SPC so that all codecs build on the Clip. Not yet real time.

2e6d604bb6 Stop hiding errors by redirecting stderr to /dev/null. If we really need to 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.

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles. 
Many #include lines adjusted to conform to the new standards.
