Erasing instruction from LLVM IR

Question

What data structures should I modify while deleting an instruction from LLVM IR. Currently, I am using only I->eraseFromParent() method to do this. It gives me a StackDump error at the end.

Answer 1

Calling eraseFromParent is the right way to do this according to the LLVM Programmer's Manual. Did you replace the uses of the instruction by something else before erasing it, though?
