* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-151-2/+3
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

| * celp: optimise ff_celp_lp_synthesis_filter()Mans Rullgard2012-08-131-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Adding instead of subtracting the products in the loop allows the compiler to generate more efficient multiply-accumulate instructions when 16-bit multiply-subtract is not available. ARM has only multiply-accumulate for 16-bit operands. In general, if only one variant exists, it is usually accumulate rather than subtract. In the same spirit, using the dedicated saturation function enables use of any special optimised versions of this. Signed-off-by: Mans Rullgard <mans@mansr.com>

* | Optimization of AMR NB and WB decoders for MIPSNedeljko Babic2012-06-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AMR NB and WB decoders are optimized for MIPS architecture. Appropriate Makefiles are changed accordingly. Cnfigure script is changed in order to support optimizations. Optimizations are enabled by default when compiling is done for mips architecture. Appropriate cflags are automatically set. Support for several mips CPUs is added in configure script. New ffmpeg options are added for disabling optimizations. The FFMPEG option --disable-mipsfpu disables MIPS floating point optimizations. The FFMPEG option --disable-mips32r2 disables MIPS32R2 optimizations. The FFMPEG option --disable-mipsdspr1 disables MIPS DSP ASE R1 optimizations. The FFMPEG option --disable-mipsdspr2 disables MIPS DSP ASE R2 optimizations.
