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
subfic r4, r5, 32
mullw r2, r2, r4
andi. r4, r3, 31775
rlwimi r4, r3, 15, 7, 11
mullw r3, r4, r5
add r2, r2, r3
srwi r3, r2, 5
andi. r3, r3, 31775
rlwimi r3, r2, 12, 22, 26
blr
Instead of:
_Trans16Bit:
.LBB_Trans16Bit_0: ; entry
slwi r2, r4, 15
rlwinm r2, r2, 0, 7, 11
andi. r4, r4, 31775
or r2, r2, r4
subfic r4, r5, 32
mullw r2, r2, r4
slwi r4, r3, 15
rlwinm r4, r4, 0, 7, 11
andi. r3, r3, 31775
or r3, r4, r3
mullw r3, r3, r5
add r2, r2, r3
srwi r3, r2, 5
andi. r3, r3, 31775
srwi r2, r2, 20
rlwimi r3, r2, 0, 22, 26

Use target-specific nodes for calls. This allows the fastcc code to not have
...
to do ugly hackery to avoid emitting code like this:
call foo
mov vreg, EAX
adjcallstackup ...
If foo is a fastcc call and if vreg gets spilled, we might end up with this:
call foo
mov [ESP+offset], EAX ;; Offset doesn't consider the 12!
sub ESP, 12
Which is bad. The previous hacky code to deal with this was A) gross B) not
good enough. In particular, it could miss cases and emit the bad code above.
Now we always emit this:
call foo
adjcallstackup ...
mov vreg, EAX
directly.
This makes fastcc with callees poping the stack work much better. Next
stop (finally!) really is tail calls.

each live in, and copy the regs from the vregs. As the very first thing we
do in the function, insert copies from the pregs to the vregs. This fixes
problems where the token chain of CopyFromReg was not enough to allow reordering
of the copyfromreg nodes and other unchained nodes (e.g. div, which clobbers
eax on intel).
