Steve Naroff 7e6f7c25bf Implement more thoughful error recovery when dealing with bogus declarator types. ... For example, the following code was resulting in spurious warnings. This was the result of Sema::GetTypeForDeclarator() synthesizing a type to hand back to the caller (in this case, "int []", instead of "struct s[]", which is invalid). struct s; struct s* t (struct s z[]) { // expected-error {{array has incomplete element type}} return z; } Strategy: Flag the error in Declarator/DeclaratorChunk. This info is later stored in the ParmVarDecl. If the decl is referenced, Sema::ParseIdentifierExpr() will check if the type is invalid. If so, it quietly returns "true", without instantiating a DeclRefExpr. This seems to work nicely. If Chris is happy with the approach, I will generalize this to all VarDecls. llvm-svn: 41521		2007-08-28 03:03:08 +00:00
