            Bug ID: 34612
           Summary: Line coverage counts in coverage reports coverage for
                    whitespace instead of code
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs

(ARMTargetLowering::PassF64ArgInRegs).

The body of the if statement is correctly shown as uncovered... but somehow
every line of the function is covered.  I think this is because the source
locations for the body precisely cover the expression, and we take the line
execution counts from the whitespace.
