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.
