Bill Wendling e5615156cc Only emit the personality function as a global value if the backend actually 
supports it. This solves this error on the Darwin x86-64 platform:

$ cat testcase.ii
struct A {
  A();
};

A *bork() {
  return new A;
}
$ llvm-g++ -arch x86_64 -c testcase.ii

Chris Lattner 4f230451e1 Fix PR1666, SPASS with the CBE and 254.gap with the CBE. 
GCC optimizes away things like ptr < NULL  to false.  To "fix" this,
have the CBE emit casts of pointers to intptr_t when doing relational
pointer comparisons.

Owen Anderson 3454dd3750 Remove RLE from the headers, since the pass itself is gone now. 
llvm-svn: 41971
 2007-09-14 22:54:46 +00:00

llvm-svn: 41968
 2007-09-14 22:33:52 +00:00
Dale Johannesen 98d3a08d8f Remove the assumption that FP's are either float or 
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

Evan Cheng 483e1ce16e Add implicit def of EFLAGS on those instructions that may modify flags. 
llvm-svn: 41962
 2007-09-14 21:48:26 +00:00
Dan Gohman 14cf78cde5 And an FoldingSetImpl::NodeID::AddInteger overload for int64_t, to avoid 
ambiguity.

 2007-09-14 20:37:18 +00:00
Dan Gohman 9da02f5ee2 Remove isReg, isImm, and isMBB, and change all their users to use 
isRegister, isImmediate, and isMachineBasicBlock, which are equivalent,
and more popular.

Dan Gohman a7b26e6bb3 Change "tmp." to "tmp" for temporaries created by ScalarEvolutionExpander 
for consistency with many other transforms.

Chris Lattner 5d13fb538f Fix a logic error in ValueIsOnlyUsedLocallyOrStoredToOneGlobal that caused 
miscompilation of 188.ammp.  Reject select and bitcast in 
ValueIsOnlyUsedLocallyOrStoredToOneGlobal because RewriteHeapSROALoadUser can't handle it.

Bill Wendling 264d4813c7 Temporary reverting r41817 
(http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070910/053370.html). It's
causing SPASS to fail.

Chris Lattner 011f91b5b2 Teach GlobalLoadUsesSimpleEnoughForHeapSRA and the SROA rewriter how to handle 
a limited form of PHI nodes.  This finally fixes PR1639, speeding 179.art up
from 7.84s to 3.13s on PPC.

llvm-svn: 41933
 2007-09-13 21:31:36 +00:00

bitcasts and phis.  This is a step to fixing PR1639.

llvm-svn: 41928
 2007-09-13 16:37:20 +00:00
Chris Lattner 2d2892ee6e Make AllUsesOfLoadedValueWillTrapIfNull strong enough to see through PHI

 2007-09-12 23:39:49 +00:00
Evan Cheng 59c39dc197 Initial support for multi-result patterns: 
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.
