[cfe-dev] Howto get from a TypedefDecl an unterlying EnumDecl

[Frank Redeker]

Hi All,

not sure if this is the right place to ask my question.

I'm writing an analyzer tool using the clang ASTConsumer. When I'm
analyzing the following piece I don't know how to get back from the
TypedefDeclto the unterlying EnumDecl

typedef enum {
	Illegal = -1,
	Init = 0,
	Run,
	Stop
} T_ENUM;


In my ast consumer

void IDB_ASTConsumer::handleDecl (Decl * decl) {
.
.
else if (EnumDecl * enumDecl = llvm::dyn_cast<EnumDecl>(decl)) {
   enumDecl->dump();
EnumDecl 0x1da43360
<T:\Projects\3.3\CLANG\source\001-005\001-One-Dimension.c:25:9,
line:30:1> line:25:9
|-EnumConstantDecl 0x1da433f0 <line:26:2, col:9> col:2 Init 'T_ENUM'
| `-IntegerLiteral 0x1da433d0 <col:9> 'int' 0
|-EnumConstantDecl 0x1da43460 <line:27:2, col:13> col:2 Illegal 'T_ENUM'
| `-UnaryOperator 0x1da43448 <col:12, col:13> 'int' prefix '-'
|   `-IntegerLiteral 0x1da43430 <col:13> 'int' 1
|-EnumConstantDecl 0x1da434a0 <line:28:2> col:2 Run 'T_ENUM'
`-EnumConstantDecl 0x1da434e0 <line:29:2> col:2 Stop 'T_ENUM'
}
else if (TypedefDecl * typedefDecl = llvm::dyn_cast<TypedefDecl>(decl)) {
   typedefDecl->getTypeForDecl()->dump();
NULL TYPE

   typedefDecl->dump();
TypedefDecl 0x1da43550
<T:\Projects\3.3\CLANG\source\001-005\001-One-Dimension.c:25:1,
line:30:3> col:3 T_ENUM 'enum T_ENUM':'T_ENUM'
}

Is there a way to access the EnumDecl from the TypdefDecl


Thanks
