* | factor some logic out of instcombine into a new SimplifyAddInst method. | Chris Lattner | 2009-11-27 | 1 | -6/+35 |
| | | | | llvm-svn: 90011 | ||||
* | factor some instcombine simplifications for getelementptr out to a new | Chris Lattner | 2009-11-27 | 1 | -0/+32 |
| | | | | | | SimplifyGEPInst method in InstructionSimplify.h. No functionality change. llvm-svn: 89980 | ||||
* | move some generally useful functions out of jump threading | Chris Lattner | 2009-11-10 | 1 | -0/+35 |
| | | | | | | into libanalysis and transformutils. llvm-svn: 86735 | ||||
* | I misread the parens, not so redundant after all. | Chris Lattner | 2009-11-10 | 1 | -4/+4 |

* | remove some redundant parens. | Chris Lattner | 2009-11-10 | 1 | -4/+4 |
| | | | | llvm-svn: 86645 | ||||
* | add a new SimplifyInstruction API, which is like ConstantFoldInstruction, | Chris Lattner | 2009-11-10 | 1 | -0/+20 |
| | | | | | | | | except that the result may not be a constant. Switch jump threading to use it so that it gets things like (X & 0) -> 0, which occur when phi preds are deleted and the remaining phi pred was a zero. llvm-svn: 86637 | ||||
* | factor simplification logic for AND and OR out to InstSimplify from instcombine. | Chris Lattner | 2009-11-10 | 1 | -24/+149 |
| | | | | llvm-svn: 86635 | ||||
* | pull a bunch of logic out of instcombine into instsimplify for compare | Chris Lattner | 2009-11-09 | 1 | -5/+93 |
| | | | | | | simplification, this handles the foldable fcmp x,x cases among many others. llvm-svn: 86627 | ||||
* | rename SimplifyCompare -> SimplifyCmpInst and split it into | Chris Lattner | 2009-11-09 | 1 | -10/+35 |
| | | | | | | | Simplify[IF]Cmp pieces. Add some predicates to CmpInst to determine whether a predicate is fp or int. llvm-svn: 86624 | ||||
* | fix ConstantFoldCompareInstOperands to take the LHS/RHS as | Chris Lattner | 2009-11-09 | 1 | -4/+2 |
| | | | | | | individual operands instead of taking a temporary array llvm-svn: 86619 | ||||
* | stub out a new libanalysis "instruction simplify" interface that | Chris Lattner | 2009-11-09 | 1 | -0/+57 |
takes decimated instructions and applies identities to them. This is pretty minimal at this point, but I plan to pull some instcombine logic out into these and similar routines. llvm-svn: 86613 |
