* Remove unneeded #includesChris Lattner2004-01-311-12/+10
| | | | | | | | Move Passes.h (which defines the interface to this file) to the top. Move statistics to the top of the file. Add a comment llvm-svn: 11034
* Make LiveVariables::HandlePhysRegUse andAlkis Evlogimenos2004-01-111-21/+11
| | | | | | | | | LiveVariables::HandlePhysRegDef private they use information that is not in memory when LiveVariables finishes the analysis. Also update the TwoAddressInstructionPass to not use this interface. llvm-svn: 10755

* Currently we cannot handle two-address instructions of the form:Alkis Evlogimenos2004-01-051-0/+9
| | | | | | | A = B op C where A == C, but this cannot really occur in practice because of SSA form. Add an assert to check that just to be safe. llvm-svn: 10682

* Remove TwoAddressInstruction from the public headers and add an IDAlkis Evlogimenos2003-12-181-2/+19

* Add TwoAddressInstructionPass to handle instructions that have two orAlkis Evlogimenos2003-12-181-0/+149
more operands and the two first operands are constrained to be the same. The pass takes an instruction of the form: a = b op c and transforms it into: a = b a = a op c and also preserves live variables. llvm-svn: 10512
