With a modified copy of LLVM (so it's probably my fault) I'm getting an assertion failure because isTwoAddrUse (in TwoAddressInstructionPass.cpp) is being called with a MachineInstr MI such that MI.getNumOperands() is 2, but MI.getDesc().getNumOperands() is 5. The assertion fails when that function calls MI.getOperand(2). My question is: is isTwoAddrUse doing the right thing here? static bool isTwoAddrUse(MachineInstr &MI, unsigned Reg, unsigned &DstReg) { const TargetInstrDesc &TID = MI.get...

Hi all, I got a interesting problem when calling getNumOperands() of CallInst. For example, call void @_Z2f2PA100_i([100 x i32]* nonnull %arraydecay) If I use getNumOperands(), it will return 2. However, if I use getCalledFunction()->getNumParams(), it will return 1. According to the IR, I think the number of operands of the call...

Can you explain me why please? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

...k I've found a bug in this method. I ran it on an MI which already had two implicit-use operands, and which defined a register with a subregindex, ie reg::lo16.

It i...

Res = cmpNumbers(I1->getNumOperands(), I2->getNumOperands()); if (Res != 0) return Res; whereas, since you never use Res unless it's non-zero, I think the following is more clear and concise: if (int Res = cmpNumbers(I1->getNumOperands(), I2->getNumOperands())) return R...

The MCInstrDesc has a method getNumDefs() which tells you how many 'out registers' that MCInst has. The 'out' registers are always at the beginning of the list. You can also use getNumOperands().
