Here is the stack when TCRETURNri64 instruction is created: #1 0x0000000802c8b4e2 in llvm::MachineFunction::CreateMachineInstr (this=0x30eb000, TID=@0x803a78940, DL={LineCol = 0, ScopeIdx = 0}, NoImp=false) at /tmp/llvm-svn/llvm/lib/CodeGen/MachineFunction.cpp:153 #2 0x00000008028ea45b in llvm::BuildMI (BB=@0x4b69378, I={<std::iterator<std::bidirectional_iterator_tag, llvm::MachineInstr, long int, llvm::MachineI...

I want to have some functions that create machine instructions, not specifying which machine function or basic block or iterator they are part of. And then I want to use that result when adding that instruction to a basic block. I'm pretty sure you can do this but we have not done this in the Mips port so far. We just use instruction builder. Anyone know how to do this best, or can point

...a TCRETURN? Sorry, my bad. I have set breakpoints by MI addresses. But it turns out that these addresses were reused and the second MIs created at these particular addressed are of interest, not the first ones. RET creation stack (created first): #1 0x0000000802c8b4e2 in llvm::MachineFunction::CreateMachineInstr (this=0x30eb000, TID=@0x803a99240, DL={LineCol = 0, ScopeIdx = 0}, NoImp=false) at /tmp/llvm-svn/llvm/lib/CodeGen/MachineFunction.cpp:153 #2 0x00000008028ea45b in llvm::BuildMI (BB=@0x4b69378, I={<std::iterator<std::bidirectional_iterator_tag, llvm::MachineInstr, long int, llvm::MachineI...

...ion? Do I need to set some key items in the MachineBasicBlock too? Is there more documentation on this subject? MachineBasicBlock * mbb = mf->CreateMachineBasicBlock( 0 ); mbb->getNumber(); TargetInstrDesc tid; tid.Opcode = TID::Branch; tid.NumOperands = 1; MachineInstr * instr = mf->CreateMachineInstr( tid, DebugLoc() ); mbb->insert( mbb->end(), instr ); Thanks, Jeff Kunkel
