--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
What kind of comment would you like to have? Normally we document what the
code is supposed to do, but here I can imagine just something like:
/* We used to clear operands[4] here, which used to be a scratch register,
but that is no longer the case. */
which I'm afraid would just confuse rather than explain anything useful.
r235698 removed all other references to operands[4] (also without adding
comment on what it used to be).

Thanks.
