* Fold the useful features of alist and alist_node into ilist, andDan Gohman2008-07-281-9/+13
| | | | | | | | | | | | | | | | | a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54146 91177308-0d34-0410-b5e6-96231b3b80d8

* Pool-allocation for MachineInstrs, MachineBasicBlocks, andDan Gohman2008-07-071-29/+30
| | | | | | | | | | | | MachineMemOperands. The pools are owned by MachineFunctions. This drastically reduces the number of calls to malloc/free made during the "Emit" phase of scheduling, as well as later phases in CodeGen. Combined with other changes, this speeds up the "instruction selection" phase of CodeGen by 10% in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53212 91177308-0d34-0410-b5e6-96231b3b80d8

* Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman2008-07-011-0/+4
| | | | | | | | | | | | | | | | | the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8

* Create a new class, MemOperand, for describing memory referencesDan Gohman2008-01-311-0/+20
| | | | | | | | | | | | | | | | | in the backend. Introduce a new SDNode type, MemOperandSDNode, for holding a MemOperand in the SelectionDAG IR, and add a MemOperand list to MachineInstr, and code to manage them. Remove the offset field from SrcValueSDNode; uses of SrcValueSDNode that were using it are all all using MemOperandSDNode now. Also, begin updating some getLoad and getStore calls to use the PseudoSourceValue objects. Most of this was written by Florian Brander, some reorganization and updating to TOT by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46585 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner2008-01-071-2/+2
| | | | | | | | | | | | | | | | | | that it is cheap and efficient to get. Move a variety of predicates from TargetInstrInfo into TargetInstrDescriptor, which makes it much easier to query a predicate when you don't have TII around. Now you can use MI->getDesc()->isBranch() instead of going through TII, and this is much more efficient anyway. Not all of the predicates have been moved over yet. Update old code that used MI->getInstrDescriptor()->Flags to use the new predicates in many places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45674 91177308-0d34-0410-b5e6-96231b3b80d8

* More cleanups for MachineOperand:Chris Lattner2007-12-301-1/+0
| | | | | | | | | | | - Eliminate the static "print" method for operands, moving it into MachineOperand::print. - Change various set* methods for register flags to take a bool for the value to set it to. Remove unset* methods. - Group methods more logically by operand flavor in MachineOperand.h git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45461 91177308-0d34-0410-b5e6-96231b3b80d8
* MachineOperand:Chris Lattner2007-12-301-7/+5
| | | | | | | | | | | | | | | | | | | - Add getParent() accessors. - Move SubReg out of the AuxInfo union, to make way for future changes. - Remove the getImmedValue/setImmedValue methods. - in some MachineOperand::Create* methods, stop initializing fields that are dead. MachineInstr: - Delete one copy of the MachineInstr printing code, now there is only one dump format and one copy of the code. - Make MachineOperand use the parent field to get info about preg register names if no target info is otherwise available. - Move def/use/kill/dead flag printing to the machineoperand printer, so they are always printed for an operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45460 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up sub-register implementation by moving subReg information back toEvan Cheng2007-11-141-1/+15
| | | | | | | | | | | | MachineOperand auxInfo. Previous clunky implementation uses an external map to track sub-register uses. That works because register allocator uses a new virtual register for each spilled use. With interval splitting (coming soon), we may have multiple uses of the same register some of which are of using different sub-registers from others. It's too fragile to constantly update the information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44104 91177308-0d34-0410-b5e6-96231b3b80d8
