How many bytes are popped in the instruction:

   popf

? Oracle’s documentation states that the size should be specified as a word or long by appending w or l to the end of the instruction but no such letters are present in the disassembly I am viewing.

    POPF/POPFD pops the word or doubleword on the top of the stack and
    stores the value in the flags register. If the operand-size attribute
    of the instruction is 16 bits, then a word is popped and the value is
    stored in FLAGS. If the operand-size attribute is 32 bits, then a
    doubleword is popped and the value is stored in EFLAGS.
