Nate Begeman a2e8779b0d Fix bug 537 test 2, which checks to make sure that we fold A+(B-A) -> B for 
integer types.  Add a couple checks to not perform these kinds of transform
on floating point values.

Chris Lattner 104002bee3 Fix a bug in my previous patch. Do not get the shift amount type (which 
is always ubyte, get the type being shifted).  This unbreaks espresso

Reid Spencer a299d6f701 Put the hack back in that removes features, causes regressions to fail, but 
allows test programs to succeed. Actual fix for this is forthcoming.

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.

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

Misha Brukman ee14fc41f1 We also have V8, so do not force every Sparc to be treated like a V9. It is 
still possible to force V9 (even if configure doesn't think it's one) via
``./configure --target=sparcv9-sun-solaris2.8'' so nothing is lost.
