comment in assembly language
In assembly, comments are usually denoted by a semicolon ;
although GAS uses # for single line comments
and /* … */ for block comments possibly spanning multiple lines.
Here is an example:
xor rax, rax ; rax ≔ false
; divisibility by four
test rcx, 3 ; are the two right-most bits set?
jnz done ; yes ⇒ not divisible by 4
setz al ; al ≔ ZF [i.e. `true`, since `jnz` above]
