POPFW pops a word from the stack and stores it in the bottom 16
bits of the flags register (or the whole flags register, on
processors below a 386).
POPFD pops a doubleword and stores it in the entire flags register.
POPF is an alias mnemonic for either POPFW or POPFD,
depending on the current BITS setting.
See also PUSHF (PUSHF).
No example here: this instruction either stops the program, or belongs to a mode this emulator does not run.
Every form of popfq the assembler accepts, from NASM's own instruction table.
The second column is the processor that introduced the form; a badge marks a form that needs
an extension, that is lockable, or that long mode dropped.
| Form | Since | Notes |
