71fb834b50 * Allow mul, shl nodes to be codegen'd as LEA (if appropriate).
* Add patterns to handle GlobalAddress, ConstantPool, etc.
  MOV32ri to materialize these nodes in registers.
  ADD32ri to handle %reg + GA, etc.
  MOV32mi to handle store GA, etc. to memory.

020d2e8e7a - Clean up the lowering and selection code of ConstantPool, GlobalAddress,
and ExternalSymbol.
- Use C++ code (rather than tblgen'd selection code) to match the above
  mentioned leaf nodes. Do not mutate and nodes and do not record the
  selection in CodeGenMap. These nodes should be safe to duplicate. This is
  a performance win.

e3f01570c1 Implement the PPC inline asm "L" modifier. This allows us to compile:
long long test(long long X) {
  __asm__("foo %0 %L0 %1 %L1" : "=r"(X): "r"(X));
  return X;
}

to:
        foo r2 r3 r2 r3

4c1aa86657 - Added option -relocation-model to set relocation model. Valid values include static, pic,
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.

proves to be worth 20% on Ptrdist/ks. Might be related to dependency

298ebf2bd8 If the false case is the current basic block, then this is a self loop.
We do not want to emit "Loop: ... brcond Out; br Loop", as it adds an extra
instruction in the loop.  Instead, invert the condition and emit
"Loop: ... br!cond Loop; br Out.

Generalize the fix by moving it from PPCDAGToDAGISel to SelectionDAGLowering.

d51425a82d Use movaps / movapd (instead of movss / movsd) to do FR32 / FR64 reg to reg
transfer.

According to the Intel P4 Optimization Manual:

Moves that write a portion of a register can introduce unwanted
dependences. The movsd reg, reg instruction writes only the bottom
64 bits of a register, not to all 128 bits. This introduces a dependence on
the preceding instruction that produces the upper 64 bits (even if those
bits are not longer wanted). The dependence inhibits register renaming,
and thereby reduces parallelism.

Not to mention movaps is shorter than movss.

45090476be Sparc actually *DOES* have a directive for emitting zeros. In fact, it requires
it, because this:

.bss
X:
.byte 0

results in the assembler warning: "initialization in bss segment".  Annoying.

6fa1f57c66 Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc.
The ABI specifies that there is a register save area at the bottom of the
stack, which means the actual used pointer needs to be an offset from
the subtracted value.

0d7db6f79a If we have zero initialized data with external linkage, use .zerofill to
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.

This patch speeds up 172.mgrid from 31.81s to 11.39s on darwin/ppc.
Many many thanks to Nate for tracking down the root cause of the issue.

c275dfa727 Custom lower VAARG for the case when we are doing vaarg(double). In this
case, the double being loaded may not be 8-byte aligned, so we have to use
our standard bit_convert game.

69d39091fe Two changes:
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
   ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
   up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.
