What does lea in this x86
This question already has an answer here:
lea
, Load Effective Address, puts the computed "memory address" in the result register. So here, rcx = rsi + 4
and rax = rsi + 0x14
.
By the way, the second line doesn't really look like it's part of the code that sets up the stack frame, rsi
is the second argument when using System V AMD64 calling conventions.
