            Bug ID: 101237
           Summary: HONOR_SIGNED_ZEROS (element_mode (t)) should be moved
                    to just HONOR_SIGNED_ZEROS (t)
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

This was found really because I copied the code from fold-const.c to match.=
pd
and there was a requested change as HONOR_SIGNED_ZEROS now handles tree typ=
es
too.
See https://gcc.gnu.org/pipermail/gcc-patches/2021-June/573811.html

from a quick grep I find:
fold-const.c:     || HONOR_SIGNED_ZEROS (element_mode (type))
fold-const.c:        && !HONOR_SIGNED_ZEROS (element_mode (type))
fold-const.c:     && !HONOR_SIGNED_ZEROS (element_mode (type)))
fold-const.c:     && !HONOR_SIGNED_ZEROS (element_mode (type)))
fold-const.c:  if (!HONOR_SIGNED_ZEROS (element_mode (type))
fold-const.c:  if (!HONOR_SIGNED_ZEROS (element_mode (type))
fold-const.c:  if (!HONOR_SIGNED_ZEROS (element_mode (type))
fold-const.c:              && !HONOR_SIGNED_ZEROS (element_mode (arg0))
fold-const.c:     && !HONOR_SIGNED_ZEROS (element_mode (arg0))
fold-const.c:              && !HONOR_SIGNED_ZEROS (element_mode (arg0))
fold-const.c:     && !HONOR_SIGNED_ZEROS (element_mode (op1)))
fold-const.c:     && !HONOR_SIGNED_ZEROS (element_mode (op2)))
fold-const.c:      if (!HONOR_SIGNED_ZEROS (element_mode (type)))=
