Inlining

Thanks to this I learned that you CANNOT put registers in both the input and clobber registers
Immediates
  • AT&T: $ prefix
  • Intel: no prefix

AT&T Intel
mv $2, %eax mv 2,eax

Addressing:

  • In AT&T, (,%rax,8) means 0 + 8*%rax

Examples

  • movl    $13, -4(%rbp) # stick 13 at memory location rbp - 4
