Handle some more real world cases of rlwimi. These don't come up that
...
regularly in "normal" code, but for things like software graphics, they
make a big difference.
For the following code:
unsigned short Trans16Bit(unsigned srcA,unsigned srcB,unsigned alpha)
{
unsigned tmpA,tmpB,mixed;
tmpA = ((srcA & 0x03E0) << 15) | (srcA & 0x7C1F);
tmpB = ((srcB & 0x03E0) << 15) | (srcB & 0x7C1F);
mixed = (tmpA * alpha) + (tmpB * (32 - alpha));
return ((mixed >> 5) & 0x7C1F) | ((mixed >> 20) & 0x03E0);
}
We now generate:
_Trans16Bit:
.LBB_Trans16Bit_0: ; entry
andi. r2, r4, 31775
rlwimi r2, r4, 15, 7, 11
