How do you set up a compare for this and where at?

The conditional jumps are throwing me for a loop.

comiss is more or less a cmp instruction for SSE. The parity flag is set if the result is unordered (i.e. either source is NaN), so the jp instruction is checking if either operand is NaN. The zero flag and carry flag are set according to the result, so the jb instruction will jump if xmm1 < xmm0.

Regardless, you can completely ignore those jcc instructions; all you should be interested in is the write. You can generally follow along with the tutorial even though it's for x86.

Thanks for the response.

The condition that needs to be compared ( 0010, integer value of 1 or 2 ) ... I'm not clear on where that is coming from.

Think I'll spend some time poking at it to see if I can figure it out.

Update : Duh!! More time thinking always helps.

Code:

newmem: //this is allocated memory, you have read,write,execute access
//place your code here
cmp [rbx+14],1
jne originalcode
nop
jmp exit


This code worked.
