retfq x86 instructions. These are variants of the ret instruction with the return offset size set explicitly, e.g. retfw is a 16-bit far ret (i.e. pops a 16-bit offset and a 16-bit segment), retfd is a 32-bit far ret (pops a 32-bit offset, followed by a 16-bit segment), etc. git-svn-id: trunk@37571 -
