Who would I talk to about getting the build bots to track clang-tools-extra?

I am new to clang ast, and trying to parse some c++ code with it.

When I am using TypedefDecl->getSourceRange() for say
typedef long double LDBL it returns the whole thing
However when I am using TypeAliasDecl->getSourceRange() for say
using LDBL = long double
it only returns the range using LDBL = long. (i.e removes the double part)

I used the code below to extract text from SourceRange
char const* first = sm.getCharacterData(r.getBegin());
 char const* last = sm.getCharacterData(pp.getLocForEndOfToken(r.getEnd()));
 return std::string(first,last);

Am I doing something wrong? How can I get the whole source range, and esp the type part of it i.e. long double part, so that I can rearrange it as typedef long double LDBL
I am using clang 3.2 with RAV

Any help will be appreciated.
