yet support.

48a1886727 CMake: Tests PERL availability with PERL_EXECUTABLE variable.

a5699a1e8b Do not use host floating point types when emitting 
ASCII IR; loading and storing these can change the
bits of NaNs on some hosts.  Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.

d021a20409 Simplify ReduceLoadWidth's logic: it doesn't need several different 
special cases after producing the new reduced-width load, because the
new load already has the needed adjustments built into it. This fixes
several bugs due to the special cases, including PR3317.

704f0d5879 Fix a recent regression. ClrOpcode is not set for i8; for i8, if 
we want to clear %ah to zero before a division, just use a
zero-extending mov to %al. This fixes PR3366.

this test into FrontendC to ensure that llvm-gcc
is available; assemble using "llvm-gcc -xassembler"
rather than "as".

c80e71ac35 CellSPU: 
- Ensure that (operation) legalization emits proper FDIV libcall when needed.
- Fix various bugs encountered during llvm-spu-gcc build, along with various
  cleanups.
- Start supporting double precision comparisons for remaining libgcc2 build.
  Discovered interesting DAGCombiner feature, which is currently solved via
  custom lowering (64-bit constants are not legal on CellSPU, but DAGCombiner
  insists on inserting one anyway.)
- Update README.

074553c4fb Allow targets to legalize operations (with illegal operands) that produces multiple values. For example, a load with an illegal operand (a load produces two values, a value and chain).

0ed6a9d7e0 Favors generating "not" over "xor -1". For example. 
unsigned test(unsigned a) {
  return ~a;
}
llvm used to generate:
movl    $4294967295, %eax
xorl    4(%esp), %eax

Now it generates:
movl      4(%esp), %eax
notl      %eax

It's 3 bytes shorter.

Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.

1c12d1b665 Calls to fmod, it turns out, are constant-folded by 
invoking the host fmod, not by lowering to frem and
constant-folding that.  Fix this so it tests what I
want to test.

5bea79c062 Fix PR3243: a LiveVariables bug. When HandlePhysRegKill is checking whether the last reference is also the last def (i.e. dead def), it should also check if last reference is the current machine instruction being processed. This can happen when it is processing a physical register use and setting the current machine instruction as sub-register's last ref.

cf901346da Use "SINT_TO_FP" instead of "UINT_TO_FP" when getting the exponent. This was 
causing the limited precision stuff to produce the wrong result for values in
the range [0, 1).
