among other things.

Also change a codegen warning to dump to stderr so it doesn't
mess with -emit-llvm output

llvm-svn: 44497
 2007-12-02 01:03:24 +00:00
Oliver Hunt aefc8fd415 Support initalisers for more than just int-typed static variables. 
We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

Christopher Lamb 7d303b2a20 Better match llvm-gcc's behavior for CodeGen naming of anonymous structs and unions. 
llvm-svn: 44490
 2007-12-01 09:20:34 +00:00
Christopher Lamb b0e6094a22 When generating the CodeGen type name of a struct, union, enum use the typedef 
name if a tag type name is not available for the type. This matches how llvm-gcc 
chooses CodeGen type names.

This means that "typedef struct {...} foo" now results in a CodeGen name of 
"struct.foo" rather than "struct."

Steve Naroff 32e44c0032 Move type compatibility predicates from Type to ASTContext. In addition, the predicates are now instance methods (they were previously static class methods on Type). 
This allowed me to fix the following hack from this weekend...

// FIXME: Devise a way to do this without using strcmp.
// Would like to say..."return getAsStructureType() == IdStructType;", but
// we don't have a pointer to ASTContext.
bool Type::isObjcIdType() const {
  if (const RecordType *RT = getAsStructureType())
    return !strcmp(RT->getDecl()->getName(), "objc_object");
  return false;
}

...which is now...

bool isObjcIdType(QualType T) const {
  return T->getAsStructureType() == IdStructType;
}

Side notes:

- I had to remove a convenience function from the TypesCompatibleExpr class.

int typesAreCompatible() const {return Type::typesAreCompatible(Type1,Type2);}

Which required a couple clients get a little more verbose...

-    Result = TCE->typesAreCompatible();
+    Result = Ctx.typesAreCompatible(TCE->getArgType1(), TCE->getArgType2());

Overall, I think this change also makes sense for a couple reasons...

1) Since ASTContext vends types, it makes sense for the type compatibility API to be there.
2) This allows the type compatibility predeciates to refer to data not strictly present in the AST (which I have found problematic on several occasions).

so that the inheritance tree is reflected in the ordering.  This allows

of some abstract class, making classof faster.

Steve Naroff 9def2b15c1 Phase 2 of making the Decl class more lightweight... 
Move Identifier/Loc instance variables (and associated getters/setters) down from Decl to ScopedDecl/FieldDecl.

Objc AST's can now inherit from Decl without getting instance variables and types that are C specific. For now, I am keeping NextDeclarator, since I believe it may be useful to ObjC. If not, it can be moved later.

Steve Naroff 5c13180a27 Fix the following redefinition errors submitted by Keith Bauer... 
[dylan:~/llvm/tools/clang] admin% cat tentative_decls.c 
// incorrectly generates redefinition error
extern int array[3];
int array[3];

// incorrectly generates a redefinition error
extern void nup(int a[3]);
void nup(int a[3]) {}

It turns out that this exposed a fairly major flaw in the type system,
array types were never getting uniqued! This is because all array types
contained an expression, which aren't unique.

To solve this, we now have 2 array types, ConstantArrayType and
VariableArrayType. ConstantArrayType's are unique, VAT's aren't.

This is a fairly extensive set of fundamental changes. Fortunately,
all the tests pass. Nevertheless, there may be some collateral damage:-)
If so, let me know!
