I am analyzing a program in ollydbg, and some instructions get disassembled as [ARG.1], eg:
MOV ESI,[ARG.1]
I tried searching for this command in assembly books, but seems as if it’s only used in ollydbg and is not a standard assembly code.
am I right?
and what does it mean?
I suspect ollydbg is trying to be helpful by reverse engineering your stack layout for you, and that
[ARG.1]is really[EBP+0x08]or the like — the first argument on the stack if you’re in a function called with the C calling convention.Not having used ollydbg in a while, I’m sure there’s a way to convince ollydbg to show you more literally what the exact opcode is.
