            Bug ID: 20389
           Summary: clang's error message for inline-asm constraint "=f"
                    should be more user-friendly
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: ahatanak at gmail.com

    Classification: Unclassified

clang issues the following error message upon encountering constraint "=f":

error: invalid output constraint '=f' in asm

Rather than simply saying the constraint is invalid, it would be better to
print a message that informs the user how the error can be corrected. For
example, gcc prints the following message:

error: output constraint 0 must specify a single register
