问题
I'm trying to debug some code for a project and I've come up against this line cmpl $0x7,0xc(%rsp). What is 0xc(%rsp), and how do I print it?
回答1:
What is 0xc(%rsp)
The memory location 12 bytes above current stack pointer. The value at that location is being compared with 7.
and how do I print it?
(gdb) print $rsp+0xc
