           Summary: Feature request: integer-overflow-detecting arithmetic
                    intrinsics
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: c

Clang has a fairly complete family of intrinsics to do integer arithmetic with
overflow detection.  They include function like __builtin_uadd_overflow, and
they are described here:

Please consider supporting these in GCC as well.
