MIPS DSP composition functions optimizations.
List of optimized routines:
- comp_func_DestinationOver
- comp_func_SourceIn
- comp_func_DestinationIn
- comp_func_DestinationOut
- comp_func_SourceAtop
- comp_func_DestinationAtop
- comp_func_XOR
- comp_func_SourceOut
- comp_func_solid_SourceOver
- comp_func_solid_DestinationOver
- comp_func_solid_SourceIn
- comp_func_solid_DestinationIn
- comp_func_solid_SourceAtop
- comp_func_solid_DestinationAtop
- copm_func_solid_XOR
- comp_func_solid_SourceOut
Previously optimized routines qt_blend_argb32_on_argb32_mips_dsp and
comp_func_Source_mips_dsp are redesigned and rewritten.
Overall improvement by running tst_bench_blendbench benchmark app
from tests/benchmarks/gui/image/blendbench/ is 27%.
