[cfe-dev] Help getting source locations for type qualifiers

[Kirill Bobyrev via cfe-dev]

Hi,

You can try getting previous token and checking whether it’s a part of the qualtype (and if so, extending SourceRange). I don’t know how to do this in a clean way (tm), but at least it should work.

The documentation seems to suggest that this should be possible via the TypeLoc::findExplicitQualifierLoc() function, which "Find[s] a type with the location of an explicit type qualifier." The implementation casts the TypeLoc to a QualifiedTypeLoc and returns the result. However, the documentation for QualifiedTypeLoc states that "Currently, we intentionally do not provide source location for type qualifiers."
