Understanding cmp Instruction in Assembly and Debugging with GDB
I’ve come across a specific instruction sequence that I need help understanding, particularly the comparison (
I’m particularly interested in the
What exactly is this
What happens if the values are not equal?
And how can I set a breakpoint at this comparison line in GDB to inspect the values before the comparison happens?
I tried to break at the memory address
cmp) operation and how to break at this point in GDB on an Intel Core i7-11700K Rocket Lake processor . It's low level assembly debugging in C and assembly mixI’m particularly interested in the
cmp instruction at 0x0000000000001413. From what I understand, it compares the value stored at [rbp-0x70] with the value currently in the eax register.What exactly is this
cmp operation checking tho? What happens if the values are not equal?
And how can I set a breakpoint at this comparison line in GDB to inspect the values before the comparison happens?
I tried to break at the memory address
0x0000000000001413 using break *0x0000000000001413, but I’m not sure if that’s the correct approach
