            Bug ID: 107724
           Summary: __builtin_{l,ll}floor* and __builtin_{l,ll}ceil* are
                    not documented
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

I found this while looking quickly into PR 107723, these two sets of built-ins
are not documented. While __builtin_{l,ll}round* set is documented.
The floor and ceil sets are even an extension on top and not part of any
standard as far as I can tell even.  They are mostly used to optimize to one
instruction for many targets.
