* | Rename AliasSet to SubRegs, to reflect changes in the surrounding code. | Dan Gohman | 2008-10-16 | 1 | -3/+3 |

* | Fix a subtle bug in DeadMachineInstructionElim's liveness | Dan Gohman | 2008-10-16 | 1 | -1/+4 |
| | | | | | | | computation. A def of a register doesn't necessarily kill live super-registers. llvm-svn: 57614 | ||||
* | Switch the MachineOperand accessors back to the short names like | Dan Gohman | 2008-10-03 | 1 | -3/+3 |
| | | | | | | isReg, etc., from isRegister, etc. llvm-svn: 57006 | ||||
* | Add debug output to this pass. | Dan Gohman | 2008-09-25 | 1 | -0/+2 |

* | Refactor the logic for testing if an instruction is dead into a | Dan Gohman | 2008-09-24 | 1 | -37/+48 |
| | | | | | | separate method. llvm-svn: 56531 | ||||
* | Set SetStore to false, to allow this pass to delete | Dan Gohman | 2008-09-24 | 1 | -1/+2 |
| | | | | | | dead loads. llvm-svn: 56529 | ||||
* | Now that DeadMachineInstructionElim is basically working | Dan Gohman | 2008-09-23 | 1 | -6/+0 |
| | | | | | | | correctly, it's not necessary to explicitly remove registers from their use-def lists. llvm-svn: 56509 | ||||
* | Track local physical register liveness. This is not the most | Dan Gohman | 2008-09-23 | 1 | -3/+53 |
| | | | | | | | efficient implementation possible, but it's pretty simple and good enough for the time being. llvm-svn: 56504 | ||||
* | Don't consider instructions with implicit physical register | Dan Gohman | 2008-09-18 | 1 | -1/+2 |
| | | | | | | defs to be necessarily live. llvm-svn: 56310 | ||||
* | Add a new MachineInstr-level DCE pass. It is very simple, and is intended to | Dan Gohman | 2008-09-17 | 1 | -0/+99 |
be used with fast-isel. llvm-svn: 56268 |
