I'm having some troubles building LLVM 3.3 (previously I was using 3.2). I'm getting a lot of errors in the various architecture support: In file included from PPCFrameLowering.h:17:0, from PPCTargetMachine.h:17, from PPCSelectionDAGInfo.cpp:15: PPCSubtarget.h:60:49: error: expected class-name before ‘{’ token PPCSubtarget.h:196:30: error: ‘RegClassVector’ has not been declared In file included from AArch64Subtarget.cpp:14:0: AArch64Subtarget.h:29:57: error: expected class-name befor...

Hi, I am able to remove the critical edges now. I only had to insert the line below in PPCTargetmachine.cpp. PM.add(createBreakCriticalEdgesPass()); However, it does not remove all the critical edges. I am getting a very weird dataflow graph (even without the Break Critical edges pass). The dataflow generated by MachineFunction::dump() for the program below is given here: http://compilers.cs.ucla...

Dear guys, I've adapted the pass in BreakCriticalEdges.cpp so I can use it before register allocation. But the pass is not changing the control flow graph of the machine function. I think it is because I am inserting the pass after the control flow graph of the machine function is built. I am inserting the pass as required by the register allocator, and I can see that the pass is

...nately changing how code generator passes are added to pass managers require that we potentially make changes on target specific parts of the backend. Examples: file "Target/X86/X86TargetMachine.cpp"; file "Target/Sparc/SparcTargetMachine.cpp"; file "Target/PowerPC/PPCTargetMachine.cpp" etc. In general, changes are required in every place in the backend where decisions are made based on the optimization level. More specifically, changes are required in the following components: 1. Instruction Selector: -- Use the effective optimization level to decide whether Fa...

PPCTargetLowering::EmitInstrWithCustomInserter has a reference to the current MachineFunction for other purposes. Can you use MachineFunction::getRegInfo instead?

Hi Gary, This does not patch cleanly for me (PPCISelLowering.cpp). Can you prepare a updated patch? Thanks, Evan On Jul 10, 2008, at 11:45 AM, Gary Benson wrote: > Cool, that worked.

Just cast both values to const TargetRegisterClass*.

You need to insert new basic blocks and update CFG to accomplish this. There is a hackish way to do this right now. Add a pseudo instruction to represent this operation and mark it usesCustomDAGSchedInserter. This means the intrinsic is mapped to a single (pseudo) node. But it is then expanded into instructions that can span multiple basic blocks. See

Would it be acceptable to change MachineInstr::getRegInfo from private to public so I can use it from PPCTargetLowering::EmitInstrWithCustomInserter?
