ppc: fix 32-bit PIC build
On 32-bit ppc, the GOT pointer must be loaded manually. This adds a "get_got" assembler macro to compute the GOT address. The "movrel" macro is updated to take an additional parameter containing the GOT address since no register is reserved for this purpose on ppc32. These changes have no effect on ppc64 builds.

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. When a function call is disguised within an inline asm block, the compiler might not adjust the stack pointer as required before a function call, resulting in the red zone being clobbered. Moving the entire function to pure asm avoids this problem and also results in somewhat better code. Originally committed as revision 24044 to svn://svn.ffmpeg.org/ffmpeg/trunk |
