%X = and Y, constantint
%Z = setcc %X, 0
instead of emitting:

test %EAX, %EAX

We now emit:

This triggers 581 times on 176.gcc for example.

Implement bitfield insert by recognizing the following pattern:
...
1. optional shift left
2. and x, immX
3. and y, immY
4. or z, x, y
==> rlwimi z, x, y, shift, mask begin, mask end
where immX == ~immY and immX is a run of set bits. This transformation
fires 32 times on voronoi, once on espresso, and probably several
dozen times on external benchmarks such as gcc.
To put this in terms of actual code generated for
struct B { unsigned a : 3; unsigned b : 2; };
void storeA (struct B *b, int v) { b->a = v;}
void storeB (struct B *b, int v) { b->b = v;}

case:
int C[100];
int foo() {

}
We now codegen:
foo:

ret
instead of:
foo:
mov %EAX, OFFSET C
mov %EAX, DWORD PTR [%EAX + 16]
ret
Other impressive features may be coming later.

Several fixes and enhancements to the PPC32 backend.
...
1. Fix an illegal argument to getClassB when deciding whether or not to
sign extend a byte load.
2. Initial addition of isLoad and isStore flags to the instruction .td file
for eventual use in a scheduler.
3. Rewrite of how constants are handled in emitSimpleBinaryOperation so
that we can emit the PowerPC shifted immediate instructions far more
often. This allows us to emit the following code:
int foo(int x) { return x | 0x00F0000; }

Codegen signed mod by 2 or -2 more efficiently. Instead of generating:
...
t:
mov %EDX, DWORD PTR [%ESP + 4]
mov %ECX, 2
mov %EAX, %EDX
sar %EDX, 31
idiv %ECX
mov %EAX, %EDX
ret
Generate:
t:
mov %ECX, DWORD PTR [%ESP + 4]
*** mov %EAX, %ECX
cdq
and %ECX, 1
xor %ECX, %EDX
sub %ECX, %EDX
*** mov %EAX, %ECX
ret
Note that the two marked moves are redundant, and should be eliminated by the
register allocator, but aren't.
Compare this to GCC, which generates:
t:
mov %eax, DWORD PTR [%esp+4]
mov %edx, %eax
shr %edx, 31
lea %ecx, [%edx+%eax]
and %ecx, -2
sub %eax, %ecx
ret
or ICC 8.0, which generates:
t:
movl 4(%esp), %ecx #3.5
movl $-2147483647, %eax #3.25
imull %ecx #3.25
movl %ecx, %eax #3.25
sarl $31, %eax #3.25
addl %ecx, %edx #3.25
subl %edx, %eax #3.25
addl %eax, %eax #3.25
negl %eax #3.25
subl %eax, %ecx #3.25
movl %ecx, %eax #3.25
ret #3.25
We would be in great shape if not for the moves.

sar %ECX, 1
shr %ECX, 30
mov %EDX, %EAX

When we really meant:
s:

mov %ECX, %EAX
sar %ECX, 1
shr %ECX, 30
add %EAX, %ECX

Apparently the GNU assembler has a HUGE hack to be compatible with really

old and broken AT&T syntax assemblers. The problem with this hack is that

This was a real pain to figure out, but is trivially easy to support: thus
we are now bug compatible with gas and gcc.

...
that have a frame pointer. This change fixes Burg. In addition, make
the necessary changes to floating point code gen and constant loading after
Chris Lattner's fixes to the asm writer. These changes fix MallocBench/gs

Fix frame pointer handling:

Reserve R0 in store/load from stack slot for building >32k offsets from SP
or FP. This also requires we use R11 rather than R0 for holding the LR
value we want to save or restore. Also, tell the register allocator not
to use R31 (our FP) in functions that have a frame pointer. These changes
fix Burg.

Note that this indicates a serious problem with the way we are emitting varargs,
but this should not be properly fixed until after 1.3.
This patch SHOULD go into 1.3.

Changes commited for Nate Begeman:
...
Use a PowerPC specific prolog epilog inserter to control where spilled
callee save regs are placed on the stack.
Get rid of implicit return address stack slot, save return address reg
(LR) in appropriate slot
Improve code generated for functions that don't have calls or access
globals
Note from Chris: PowerPCPEI will eventually be eliminated, once the
functionality is merged into CodeGen/PrologEpilogInserter.cpp
