Andrew Lenharth 331380b2e2 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.

Nate Begeman 1bf8927518 Commit fix for generating conditional branch pseudo instructions that 
avoids dereferencing the end() iterator when selecting the fallthrough
block.  This requires an ilist change.

Nate Begeman 54c022156d Commit a small improvement that is already in the x86 and ia64 backends to 
not generate unnecessary register copies.  This improves compile time by
2-5% depending on the test.

Nate Begeman 2829f330a3 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.

Reid Spencer 8086cfaa6a For PR572: 
Undefine the PPC symbol which is defined by Linux/PPC (erroneously) so it
doesn't pollute the user namespace and clash with our namespace declarations.

Nate Begeman 60cf00c982 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
        srwi r2, r2, 20
        rlwimi r3, r2, 0, 22, 26

Andrew Lenharth 39edea8306 Fix 2005-05-12-Int64ToFP 
The issue is there is no unsigned -> double conversion, only signed.  So I
need to test the sign and do a different thing depending on it.  Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.
