<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>
