* Pool-allocation for MachineInstrs, MachineBasicBlocks, andDan Gohman2008-07-071-31/+92
| | | | | | | | | | | 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. llvm-svn: 53212

* move MachineFrameInfo::CreateFixedObject out of line, give MachineFrameInfoChris Lattner2008-01-251-1/+14

| | | | llvm-svn: 45469
* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-15/+11
| | | | | | | | | | | | | | that "machine" classes are used to represent the current state of the code being compiled. Given this expanded name, we can start moving other stuff into it. For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from MachineFunction into it. Update all the clients to match. This also reduces some needless #includes, such as MachineModuleInfo from MachineFunction. llvm-svn: 45467

* Eliminate the remaining uses of getTypeSize. ThisDuncan Sands2007-11-051-2/+2
| | | | | | | | | | | | | | should only effect x86 when using long double. Now 12/16 bytes are output for long double globals (the exact amount depends on the alignment). This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. llvm-svn: 43688

* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-4/+4
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
