He only needs to create the new function and splice in the body of the old one. Gabriel: look at Function::getBasicBlockList() and iplist<>::splice(iterator, iplist). Something like Function *NewF = Function::Create(NewFnType, OldF->getLinkage()); NewF->getBasicBlockList().splice(NewF->begin(), OldF->getBasicBlockList()); NewF->takeName(OldF); OldF->eraseFromParent(); is probably what you&...

But for a general function it'd be easy enough to call replaceAllUsesWith() on each old argument, since there's no need to worry about preserving the integrity of the old function. >> Gabriel: look at Function::getBasicBlockList() and >> iplist<>::splice(iterator, iplist).

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

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?

Hi all, I am trying to extend a FunctionType to include new parameters. In particular, I want to ensure that the main function has been declared with both argsc and argsv. However there seems to be no easy way to accomplish this: llvm::Function::getFunctionType() returns a a reference to a const object, while modifying only the argument list yields an error during verification since the

I'm now writing a pass and I wanna ask a question about how to duplicate the function and add duplicated arguments in llvm, for example: func(int a, char *b) -> func(int a, char *b, int a1, char *b1) I'm now stuck at using "getOrInsertFunction" and how to handle "getArgumentList", please share your opinion, thanks a lot!

Hi, In my code generator, I need to prepare a block and add instructions to it, then insert this block in a function defined later (that is I cannot create the function at the beginning stage become some info are not available yet). I tried to create a block without any "parent" (BasicBlock::Create(getGlobalContext(), "init"), fill it, but how to link it with the created

...o create a block without any "parent" (BasicBlock::Create(getGlobalContext(), "init"), fill it, but how to link it with the created function? (i read about "moveBefore" and "moveAfter" but these methods are not usable in this context... You can use Function::getBasicBlockList(). That list supports fully general list operations like "insert", so you can just plop it in wherever you'd like it. -Chris
