* | Fix PR7096. When a block containing multiple defs is tail duplicated, the | Bob Wilson | 2010-05-10 | 1 | -1/+1 |
| | | | | | | | SSAUpdater for the value from the first def may see uses of undefined values, because the later defs will not have been updated yet. llvm-svn: 103407 | ||||
* | Combine the implementations of the core part of the SSAUpdater and | Bob Wilson | 2010-05-04 | 1 | -437/+109 |
| | | | | | | MachineSSAUpdater to avoid duplicating all the code. llvm-svn: 103060 | ||||
* | Update MachineSSAUpdater with the same changes I made for the IR-level | Bob Wilson | 2010-04-26 | 1 | -122/+428 |
| | | | | | | | SSAUpdater. I'm going to try to refactor this to share most of the code between them. llvm-svn: 102353 | ||||
* | stop using DebugLoc::getUnknownLoc() | Chris Lattner | 2010-04-02 | 1 | -1/+1 |

* | fix missing #includes. | Chris Lattner | 2010-02-10 | 1 | -0/+1 |

* | move target-independent opcodes out of TargetInstrInfo | Chris Lattner | 2010-02-09 | 1 | -8/+8 |
| | | | | | | | | | into TargetOpcodes.h. #include the new TargetOpcodes.h into MachineInstr. Add new inline accessors (like isPHI()) to MachineInstr, and start using them throughout the codebase. llvm-svn: 95687 | ||||
* | Change errs() to dbgs(). | David Greene | 2010-01-05 | 1 | -2/+2 |

* | Watch out for duplicated PHI instructions. | Evan Cheng | 2009-12-07 | 1 | -3/+37 |

* | Pre-regalloc tale duplication. Work in progress. | Evan Cheng | 2009-12-07 | 1 | -1/+11 |

* | If BB is empty, insert PHI before end() instead of front(). | Evan Cheng | 2009-12-07 | 1 | -3/+6 |

* | Don't try to be cute with undef optimization here. Let ProcessImplicitDefs ↵ | Evan Cheng | 2009-12-04 | 1 | -27/+17 |
| | | | | | | handle it. llvm-svn: 90566 | ||||
* | - If the reaching definition is an undef and the use is a PHI, add the ↵ | Evan Cheng | 2009-12-04 | 1 | -11/+15 |
| | | | | | | | | implicit_def to the end of the source block. - When reaching value is replaced with another, update the cache as well. llvm-svn: 90501 | ||||
* | Handle undef values properly. | Evan Cheng | 2009-12-03 | 1 | -15/+38 |

* | Fill out codegen SSA updater. It's not yet tested. | Evan Cheng | 2009-12-03 | 1 | -8/+229 |

* | Skeleton for MachineInstr level SSA updater. | Evan Cheng | 2009-12-02 | 1 | -0/+108 |
