             Bug #: 50060
           Summary: intrinsics not folded by the middle-end
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: paolo.carlini@oracle.com


Following up to 49813, this is a list of intrinsics, corresponding to C89 and
C99 <math.h> (and C++11 <cmath>) facilities, not yet folded by the middle-end.

C89:
- fmod
- frexp

C99:
- lgamma
- llrint
- lrint
- nearbyint
- nextafter
- nexttoward
- remquo
- rint

Note: in the audit trail of PR49813, Comment #51, Jakub explains that nextafter
and nexttoward should be doable rather easily.
