# Date Author Comment

Separate format conversion DSP functions from DSPContext.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

PPC: convert Altivec FFT to pure assembler

On PPC a leaf function has a 288-byte red zone below the stack pointer,
sparing these functions the chore of setting up a full stack frame.

compiler might not adjust the stack pointer as required before a...
