Chris Lattner 51b01bf8a5 Make load->store deletion a bit smarter. This allows us to compile this: 
void test(long long *P) { *P ^= 1; }

into just:

_test:
	movl	4(%esp), %eax
	xorl	$1, (%eax)
	ret

instead of code like this:

_test:
	movl	4(%esp), %ecx
        xorl    $1, (%ecx)
	movl	4(%ecx), %edx
	movl	%edx, 4(%ecx)
	ret

Chris Lattner 89f36e6b21 Finally implement correct ordered comparisons for PPC, even though 
the code generated is not wonderful.  This turns a miscompilation into
a code quality bug (noted in the ppc readme).  This fixes PR642, which
is over 2 years old (!).  Nate, please review this.

Chris Lattner a30be59fa2 Fix a nasty corner case that Neil noticed in PR1900, where we would 
incorrectly apply the multiple include optimization to files with 
guards like:

#if !defined(x) MACRO

where MACRO could expand to different things in different contexts.
Thanks Neil!

Ted Kremenek 1b0ea82459 Substituted all instances of the string "Objc" for "ObjC". This fixes

support in clang.

Duncan Sands c50c210d76 I doubt the address of the Error string was intended

Ted Kremenek 9dbf8a93a7 Renamed SimulVertex, SimulGraph, and SimulEngine to: 
ExplodedNode, ExplodedGraph  (to match the vocabulary in the RHS paper)
  ReachabilityEngine
  
The implementation of the core of the path-sensitive dataflow solver has
been de-templatized and places in ReachabilityEngine.cpp.

The solver is still incomplete.

serialized bitcode.
