Evan Cheng b268184363 Last check-in was bogus. There is no need to align the stack if the function is a leaf function (and without alloca).

 2007-01-20 02:08:16 +00:00
Evan Cheng 7ab6fa3a67 We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space.

Evan Cheng fc74e2de26 GetRegForReload() now keeps track which registers have been considered and rejected during its quest to find a suitable reload register. This avoids an infinite loop in case like this: 
t1 := op t2, t3
  t2 <- assigned r0 for use by the reload but ended up reuse r1
  t3 <- assigned r1 for use by the reload but ended up reuse r0
  t1 <- desires r1
        sees r1 is taken by t2, tries t2's reload register r0
        sees r0 is taken by t3, tries t3's reload register r1
        sees r1 is taken by t2, tries t2's reload register r0 ...

Reid Spencer a94d394ad2 For PR1043: 
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Reid Spencer c050af9126 Clean up some code around the store V, (cast P) -> store (cast V), P 
transform. Change some variable names so it is clear what is source and
what is dest of the cast. Also, add an assert to ensure that the integer
to integer case is asserting if the bitwidths are different. This prevents
illegal casts from being formed and catches bitwidth bugs sooner.

Reid Spencer 726b68bc6e Fix a regression in the last patch. When constructing a BitMask, be careful

Make Node::update handle edges which dominate and are tighter than

Replace makeEqual's "squeeze theorem" code. Fixes miscompilation.

Gate the calls to defToOps and opsToDef. Before this, we were getting IG
edges about values which weren't even defined in the dominated area. This
