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."

Fariborz Jahanian da6c012ee7 Added a new class for Interfaces qualified by protocol list. 
Protocols are now sorted and made unique in the list.
Enhanced pretty printer for @interface (So, I can see the protocol list).

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!
