            Bug ID: 46554
           Summary: Unsigned _Fract fixed point literals do not error even
                    when they overflow
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org

Given the code:

  unsigned _Fract f = 2.0ur;

compiled with

  clang -cc1 -ffixed-point

Clang should give an error saying that the fixed point literal is too large to
fit in the type. However, it does not.

This is probably an issue in NumericLiteralParser or SemaExpr.
