Chris Lattner	5ca42cd342	Fix PR1850 by removing an unsafe transformation from VMCore/ConstantFold.cpp. ... Reimplement the xform in Analysis/ConstantFolding.cpp where we can use targetdata to validate that it is safe. While I'm in there, fix some const correctness issues and generalize the interface to the "operand folder". llvm-svn: 44817	2007-12-10 22:53:04 +00:00
Chris Lattner	8959334b96	Make this a *real* header: ... 1. Remove using namespace llvm; 2. Remove unneeded #includes. 3. Add #include guard. Also add prototypes for new code moved from transformutils to libanalysis. llvm-svn: 33682	2007-01-30 23:47:35 +00:00
Chris Lattner	59ba02e557	Change constant folding APIs to take an optional TargetData, and change ... ConstantFoldInstOperands/ConstantFoldCall to take a pointer to an array of operands + size, instead of an std::vector. llvm-svn: 33669	2007-01-30 23:12:47 +00:00
John Criswell	0893d5847f	Move some constant folding functions into LLVMAnalysis since they are used ... by Analysis and Transformation passes. llvm-svn: 24038	2005-10-27 16:00:10 +00:00
