            Bug ID: 112432
           Summary: Internal-fn: The [i|l|ll]rint family don't support
                    FLOATN
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pan2.li at intel dot com
  Target Milestone: ---

The [i|l|ll]rint family are defined as DEF_INTERNAL_FLT_FN instead of
DEF_INTERNAL_FLT_FLOATN_FN in the internal-fn.def. Thus, the standard name =
like
lrint<m><n> cannot be expanded when _Float16 type is given.

Is there any reason/background that [i|l|ll]rint can honor FLOATN or not? L=
ist

DEF_INTERNAL_FLT_FN (IFLOOR, ECF_CONST, lfloor, unary_convert)
