             Bug #: 15095
           Summary: Inconsistent Paren Locations for vector literal
                    CompoundLiteralExpr compared to typical expected
                    behavior
           Product: clang
           Version: trunk
          Platform: PC

            Status: NEW
          Severity: enhancement

Proposed patch to resolve reported issue.

For a vector literal expression represented as a CompoundLiteralExpr, clang
reports that the source range of the generated CompoundLiteralExpr is the
source range of the vector "cast" operation marking the expression as a vector
literal.  This is inconsistent with the general notion of a
CompoundLiteralExpr's source range, which should be a superset of the source
ranges of all its children, enclosed in braces or parens.  

The attached proposed patch to SemaExpr.cpp and Sema.h results in source
location information for vector literals that is more consistent with the
typical meaning of a CompoundLiteralExpr's source location.
