Hi, all: I want to know how to dump the a instruction in gdb. I can dump a Module use M.dump(), also is there any such print function which can be used in gdb for a single instruction and its operand? also I'm confused with the concept about " the type a instruction", why a instruction should have a type, how we decide the type of a instruction? for example, for the following instruction: %i = alloca i32, align 4 ; <i32*> [#uses=2] the following isa is true: isa<PointerType>(II->getType()) is that the type of a instruction is decided by the type of the result operand? and it has nothing to do with the opcode for a instruction? thanks. tianwei -------------- next part -------------- An HTML attachment was scrubbed...
