             Bug #: 14217
           Summary: Rewriter RemoveText(SrouceRange&) method not working
                    on FunctionDecl
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs

Calling RemoveText on an instance of Rewriter, passing a FunctionDecl source
range makes no changes to the rewriter buffer.
I tried to remove a function declaration (+ definition) from within an
ASTConsumer derived class (HandleTranslationUnit method).

Various tries:

FunctionDecl* function;
...
rewriter.RemoveText(function->getLocation()); // removes the function name
rewriter.RemoveText(function->getSourceRange()); // doesn't remove anything

const char* start_location =
Context.getSourceManager().getCharacterData(function->getLocation());
const char* end_location =
Context.getSourceManager().getCharacterData(function->getBodyRBrace());
rewriter.RemoveText(function->getLocation(), (int)(end_location -
start_location)); // removes the name, the parameters and the body, but not the
return type
