* These files don't need to include <iostream> since they include ↵Brian Gaeke2004-07-211-1/+0

| | | | | | MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function. llvm-svn: 14389
* Adjust to new TargetMachine interfaceChris Lattner2004-06-021-1/+1

* Beautify debug output.Alkis Evlogimenos2004-02-181-3/+8

* This pass should not require phi elimination or live variableAlkis Evlogimenos2004-02-151-13/+13
| | | | | | | analysis. It should only preserve them and update LiveVariables if it already ran. llvm-svn: 11479
* Use newly added next() and prior() utility functions.Alkis Evlogimenos2004-02-141-2/+2
| | | | llvm-svn: 11430
* Remove getAllocatedRegNum(). Use getReg() instead.Alkis Evlogimenos2004-02-131-6/+6
| | | | llvm-svn: 11393
* Change MachineBasicBlock's vector of MachineInstr pointers into anAlkis Evlogimenos2004-02-121-5/+5
| | | | | | | | | ilist of MachineInstr objects. This allows constant time removal and insertion of MachineInstr instances from anywhere in each MachineBasicBlock. It also allows for constant time splicing of MachineInstrs into or out of MachineBasicBlocks. llvm-svn: 11340
* Added missing include.Tanya Lattner2004-02-051-0/+1
| | | | llvm-svn: 11129
* Modify the two address instruction pass to remove the duplicateAlkis Evlogimenos2004-02-041-57/+67
| | | | | | operand of the instruction and thus simplify the register allocation. llvm-svn: 11124
* Revert changes. Will implement this using a different set of primitivesAlkis Evlogimenos2004-02-021-9/+3
| | | | llvm-svn: 11091
* Correctly update def/use information for modified machine operands.Alkis Evlogimenos2004-02-021-3/+9
| | | | llvm-svn: 11087
* Fix, correctly this time, the computation of the return valueChris Lattner2004-01-311-15/+16
| | | | | | | | | Fix a spello Tighten up the assertion checking No functionality changes. llvm-svn: 11036
* * Fix incorrect computation of the runOnMachineFunction return valueChris Lattner2004-01-311-30/+23
| | | | | | * Turn a bunch of instance variables into automatic variables llvm-svn: 11035
* 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
* fix warningChris Lattner2004-01-051-1/+1

* 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
* Update description.Alkis Evlogimenos2004-01-041-5/+10
| | | | llvm-svn: 10681
* Remove TwoAddressInstruction from the public headers and add an IDAlkis Evlogimenos2003-12-181-2/+19
| | | | | | instead, since this pass doesn't expose any state to its users. llvm-svn: 10520
* 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
