long %test(ubyte, short, long %X, long %Y) {
%A = xor long %X, -1

ret long %B

to this:
test:
save -96, %sp, %sp
andn %i4, %i2, %i0
andn %i5, %i3, %i1
restore %g0, %g0, %g0
retl
nop
instead of this:
test:
save -96, %sp, %sp
xor %i2, -1, %l0
xor %i3, -1, %l1
and %i4, %l0, %i0
and %i5, %l1, %i1
restore %g0, %g0, %g0
retl

test:

add %i0, 1, %l0
xor %l0, 123, %i0
restore %g0, %g0, %g0
retl
nop
for example. I guess it would make sense to add reg/reg versions too.

from the DAGToDAG cpp file. This adds pattern support for vector and
scalar fma, which passes test/Regression/CodeGen/PowerPC/fma.ll, and
does the right thing in the presence of -disable-excess-fp-precision.
Allows us to match:
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = mul <4 x float> %tmp1, %tmp1
%tmp3 = add <4 x float> %tmp2, %tmp1
store <4 x float> %tmp3, <4 x float> *%a
ret void
}
As:
_foo:
li r2, 0
lvx v0, r2, r3
vmaddfp v0, v0, v0, v0
stvx v0, r2, r3
blr
Or, with llc -disable-excess-fp-precision,
_foo:

lvx v0, r2, r3

first before the chain.

int X;

x += X + 37;
return x;

If chain operand is selected first, we would generate:

movl 4(%esp), %ecx
leal 37(%ecx,%eax), %eax
rather than
movl $37, %eax
addl 4(%esp), %eax
addl X, %eax
which does not require %ecx. (Due to ADD32rm not matching.)

Use new PPC-specific nodes to represent shifts which require the 6-bit
...
amount handling that PPC provides. These are generated by the lowering code
and prevents the dag combiner from assuming (rightfully) that the shifts
don't only look at 5 bits. This fixes a miscompilation of crafty with
the new front-end.

Several things:
...
1. Remove redundant type casts now that PR673 is implemented.
2. Implement the OUT*ir instructions correctly. The port number really
*is* a 16-bit value, but the patterns should only match if the number
is 0-255. Update the patterns so they now match.
3. Fix patterns for shifts to reflect that the shift amount is always an
i8, not an i16 as they were believed to be before. This previous fib
stopped working when we started knowing that CL has type i8.
4. Change use of i16i8imm in SH*ri patterns to all be imm.

Add an initial hack at legalizing GlobalAddress into the appropriate nodes
...
on Darwin to remove smarts from the isel. This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file. However, we can currently emit stuff like
this: :)
li r2, lo16(L_x$non_lazy_ptr)
lis r3, ha16(L_x$non_lazy_ptr)
lwzx r2, r3, r2
The obvious improvements will follow.
