Hi guys, I seem to have hit an issue where my brain no longer seems to be working. I can't for the life of me remember how to get the resulting address from combining two registers. For example, I have a compare:
Code:
comiss xmm7,[rcx+rbx+70]

I am trying to get the address of just [rcx+rbx]. I setup a symbol basePTR and tried doing:
Code:
push eax
mov eax, [rcx+rbx]
mov [basePTR], eax
pop eax

But this doesn't seem to be working. I know it's probably quite simple but I just can't seem to figure it out.

Code:
mov eax, [rcx+rbx]

EAX is a 32-bit register, RCX and RBX are 64-bit registers.

This should work for you:
Code:
push rax
lea rax, [rcx+rbx] // Notice this is a lea, not a mov
mov [basePTR], rax
pop rax


EDIT, you can also do:
Code:
lea rax, [rcx+rbx+70]
