            Bug ID: 118592
           Summary: Add builtins/const folding for the new C23 math
                    functions
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

List of functions (almost definitely not complete):
atan2pi
atanpi
asinpi
tanpi
sinpi
cospi

Note I don't expect this to be done for GCC 15. But I am filing this just to
keep track of it and so it does not get forgotten about.
