Improve and elimination. On PPC, for:
bool %test(int %X) {
%Y = and int %X, 8
%Z = setne int %Y, 0
ret bool %Z
}
we now generate this:
rlwinm r2, r3, 0, 28, 28
srwi r3, r2, 3
instead of this:
rlwinm r2, r3, 0, 28, 28
srwi r2, r2, 3
rlwinm r3, r2, 0, 31, 31
I'll leave it to Nate to get it down to one instruction. :)
