Jakob Stoklund Olesen dbb58d2974 Revert "Replace a big gob of old coalescer logic with the new CoalescerPair class." 
Whiny buildbots.

Sean Callanan 562a5a3904 Improved printing of LLVM IR. We now print 
complete instructions rather than simply their
opcodes.

Devang Patel 0dc3c2d37e Use ValueMap instead of DenseMap. 
The ValueMapper used by various cloning utility maps MDNodes also.

Sean Callanan 16ad5faeeb Extensive code cleanup of the expression command. 
- Rationalized EvaluateExpression to remove a lot
  of nesting; also added comments to make it easy
  to find what's happening where
- Made ExecuteRawCommandString subcontract out to
  EvaluateExpression
- Minor logging improvements

Jakob Stoklund Olesen f38e6720cc Replace a big gob of old coalescer logic with the new CoalescerPair class. 
CoalescerPair can determine if a copy can be coalesced, and which register gets
merged away. The old logic in SimpleRegisterCoalescing had evolved into
something a bit too convoluted.

Fariborz Jahanian 9b5528d278 Patch to correctly mangle block helper functions 
when block literal is declared inside a ctor/dtor.
Fixes radr 8096995.

llvm-svn: 106700
 2010-06-24 00:08:06 +00:00
Devang Patel d8dedee96d Use available typedef for " DenseMap<const Value*, Value*>". 
llvm-svn: 106699
 2010-06-24 00:00:42 +00:00
Devang Patel b8f11de105 Cosmetic change. 
Do not use "ValueMap" as a name for a local variable or an argument.

Gabor Greif 1abbde3103 use ArgOperand accessors 
llvm-svn: 106697
 2010-06-23 23:38:07 +00:00
Sean Callanan 1d389c4b02 Added the temporary -i option to expr, which 
switches the expression parsing over to use the
LLVM IR as opposed to Clang ASTs.  Right now,
that functionality only logs.

Bill Wendling f470747a36 We are missing opportunites to use ldm. Take code like this: 
void t(int *cp0, int *cp1, int *dp, int fmd) {
  int c0, c1, d0, d1, d2, d3;
  c0 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
  c1 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
  /* ... */
}

It code gens into something pretty bad. But with this change (analogous to the
X86 back-end), it will use ldm and generate few instructions.

llvm-svn: 106692
 2010-06-23 22:48:06 +00:00
Ted Kremenek 574f304631 Add 'VisitEndAnalysis' callback to Checker class. This callback is called by GRExprEngine 
when the worklist algorithm has terminated.  This allows some checkers to do a post-analysis
phase after all paths have been analyzed.

llvm-svn: 106689
 2010-06-23 22:08:00 +00:00
Gabor Greif 5f5a864539 minor enhancement to llvm::isFreeCall API: return CallInst; no functional change

standard output, resolving a crasher.

Eric Christopher 5fed9b7c6c Update according to feedback. 
llvm-svn: 106677
 2010-06-23 20:49:35 +00:00
Rafael Espindola ef49815638 Add an extra-library-path option to the plugin. This is used to support 
having a library both as bitcode and native code. We want to use the
bitcode first, but if codegen produces new undefined references we have to use
the native code to satisfy those references.

Gold has no notion of bitcode and native search directories, so instead it has
an API where the plugin can instruct it to look for the libraries it is passing
to it. This patch uses that API.

Bruno Cardoso Lopes 30a28d6588 Fix a tblgen bug. 
Given the pattern below as an example:
list<dag> Pattern = [(set RC:$dst, (v4f32 (shufp:src3 RC:$src1,
                            (mem_frag addr:$src2))))];

The right reference resolving should lead to:
list<dag> Pattern = [(set VR128:$dst, (v4f32 (shufp:src3 VR128:$src1,
                            (mem_frag addr:$src2))))];
But was yielding:
list<dag> Pattern = [(set VR128:$dst, (v4f32 (shufp VR128:$src1,
                            (mem_frag addr:$src2))))];

Fix this by passing the right name when creating a new DagInit node.

Dale Johannesen d24c66b4a3 Do not do tail calls to external symbols. If the 
branch turns out to be ARM-to-Thumb or vice versa
the linker cannot resolve this.  8120438.

If this optimization is going to be useful we probably
need a compiler flag "assume callees are same architecture"
or something like that.

Bill Wendling a136521a17 MorphNodeTo doesn't preserve the memory operands. Because we're morphing a node 
into the same node, but with different non-memory operands, we need to replace
the memory operands after it's finished morphing.

Daniel Dunbar 4df321b7ad Revert r106263, "Fold the ShrinkDemandedOps pass into the regular DAGCombiner pass,"... it was causing both 'file' (with clang) and 176.gcc (with llvm-gcc) to be miscompiled.

Jim Grosbach a8ea498171 When using libcall expansions for the atomic intrinsics, the explicit 
MEMBARRIER fences aren't necessary for ARM. Tell the combiner to fold them
away.

 2010-06-23 16:08:49 +00:00
Jim Grosbach b58c08b0ba Some targets don't require the fencing MEMBARRIER instructions surrounding 
atomic intrinsics, either because the use locking instructions for the
atomics, or because they perform the locking directly. Add support in the
DAG combiner to fold away the fences.
