[cfe-dev] What are canonical Types in Clang

When I parse this code with an AST parser:
char rouge; // tomate is probably one of your classes so I just changed the type of the field.
typedef struct _poire kudamono;
|I have a|clang::TypedefDecl| then I get the|clang::QualType| of the typedef with|clang::TypedefDecl::getUnderlyingType()|
With the |QualType| if I use the |getAsString| method I can find the
"struct _poire" |std::string|. All this is Ok.
The problem is if I try to see if this type is a canonical type, with
|QualType::isCanonical()|, it returns false.
So I try to get the canonical type with
|QualType::getCanonicalType().getAsString()| and it returns the same
string "struct _poire".
according to the clang reference on type
http://clang.llvm.org/docs/InternalsManual.html#canonical-types , I
thought that the isCanonical() should return true when no typedef is
So what are really canonical type?
