Hi,
You can use getCanonicalType() to look through the typedefs, for example:
QualType SrcCanonType = SrcExpr()->getType().getCanonicalType(),
DestCanonType = DestType.getCanonicalType();
if (const BuiltinType *Src = SrcCanonType->getAs<BuiltinType>())
if (const BuiltinType *Dest = DestCanonType->getAs<BuiltinType>()) {
if (Src.getKind() == Dest.getKind()) {
// do something
} else {
// do something else
}
}

Kirill and Artem,
My original approach is dyn_cast the type pointer to TypedefType recursively since I need to take
nested typedef into consideration.
typedef foo FOO;
typedef FOO MyFoo;
MyFoo b = (MyFoo)(a);
The recursive call is kinda of like,
QualType getUnderlyingType(QualType QT) {
if (const TypedefType *TT = dyn_cast(QT)) {
TypedefNameDef TND = TT->getDecl();
return getUnderlyingType(TND->getUnderlyingType());
}
return QT;
}
Both of you suggested canonical type, I tried and it works.
QualType SrcCanonType = SrcExpr()->getType().getCanonicalType(),
const BuiltinType *Src = SrcCanonType->getAs()
I guess getCanonicalType() way is preferred?
