91bc570aac With setOperationAction(ISD::UINT_TO_FP, MVT::i64, Expand), Legalize 
should be able to handle this case.  The code is there, so let's see
if it works.

a2f68cf0f9 When compiled with GCC 4.0, a latent bug was exposed where both SparcV9 
and the target independant register allocator were both using a class named
'LiveRange'.  This lead to the target independant code calling code in the
SparcV9 backend, which crashed.  Fixed by renaming SparcV9's LiveRange to
V9LiveRange.

47cd13d42a 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

7391051c20 HP-UX system headers make a mess of isinf(), so much so that gcc fixincludes 
can't patch it up for c++ (works in C though)

720fbd937a Don't look for __builtin_ffs, we'll never see it from llvm-gcc and there's 
not reason to include it for other front ends.

0366a913ad PPC "branch and link" instructions are branches in the PPC sense, but not 
in the LLVM code generator sense (they are calls).  Don't mark them as such,
which fixes the regressions on the ppc tester last night

ba222e3e99 Some cleanups for compilation with GCC 4.0.0 to remove warnings: 
* Use C++ style casts, not C style casts
* Abstract base classes should have virtual destructor.

2fd2e53f6a Teach reginfo how to deal with ADJSTACKPTRri, allowing us to generate: 
add %ESP, 20
        jmp %EDX  # TAIL CALL

instead of:
        add %ESP, -8
        add %ESP, 28
        jmp %EDX  # TAIL CALL
