Mans Rullgard	6cbf2420b9	PPC: use Altivec IMDCT only for supported sizes The Altivec IMDCT works with size 32 and higher only. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Alex Converse	187a537904	Convert some undefined 1<<31 shifts into 1U<<31. According to ISO 9899:1999 S 6.5.7/4: The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1× 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined.	14 years ago

Måns Rullgård	a46b84d120	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	15 years ago

Romain Dolbeau	e45a2872fa	1) remove TBL support in PPC performance. It's much more useful to use the PMCs, and with Apple's CHUD it's fairly easy too.
