whole declaration specifier instead of trying to replace parts of it. As Manuel pointed out earlier, things like function pointer and member pointer types will break with TypeLoc because the identifier is buried in the type definition.<o:p></o:p></span></p>

<br>
Given this c++ code:<br>
<br>
const MyType *a;<br>
<br>
The TypeSourceInfo from the VarDecl provides a TypeLoc that claims the type starts at "MyType" not "const". Is this by design or is there a bug here?<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">QualifiedTypeLoc does not store location information for the type qualifiers. This is "intentional" but clearly not ideal for tooling clients of type location information. Since
the decl-specifiers for such a declaration can be in any order, the source range for such a type isn't necessarily going to be useful, and you may be able to get the information you're looking for by just looking at the start location of the Decl.<o:p></o:p></p>
