Argyrios Kyrtzidis 694dda1e4e Implicitly defined functions were getting the DeclContext of the function where they appeared, causing the bug: http://llvm.org/bugs/show_bug.cgi?id=2266.
Fix it by making implicitly defined functions get the DeclContext of translation unit.

Steve Naroff 08899ff85d Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().
This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

Douglas Gregor 556877c1e6 This patch adds very basic support for parsing and type-checking class
inheritance in C++. It'll parse the base-specifier list, e.g.,

 class D : public B1, virtual public B2 { };

and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

llvm-svn: 49621
2008-04-13 21:07:44 +00:00
Chris Lattner 861a226586 This patch is just the easy part of the class names patch, which
allows the parsing of "class" in addition to "struct" and "union" to
declare a record.  So this patch allows:

 class C { };
 class C c1;

But it does not contain the lookup bits, so this won't work yet:

 C c2;

Chris Lattner c5ffed4a66 Introduce ContextDecl, patch by Argiris Kirtzidis!
-Added ContextDecl (no TranslationUnitDecl)
-ScopedDecl class has a ContextDecl member
-FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily
-FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context.
-Moved Decl class to a "DeclBase.h" along with ContextDecl class
-CurContext is handled by Sema

Steve Naroff 778927532d Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort.
I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-)

Steve Naroff 2fc93f5c43 Two changes to Sema::LookupDecl() interface.
(1) Remove IdLoc (it's never used). 
(2) Add a bool to enable/disable lazy builtin creaation (defaults to true).

This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit.

To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness. 

llvm-svn: 49087

Chris Lattner b3a176da9f Various parts of the standard require something to be an "incomplete or
object type".  Add a predicate that checks exactly this, as it is equivalent
to checking ot see if the type is *not* a function type, which is faster
to check.

Chris Lattner daaa8ba77e 1) Enforce C99 6.7.3p2: "Types other than pointer types derived from
object or incomplete types shall not be restrict-qualified."

2) Warn about qualifiers on function types: C99 6.7.3p8: "If the 
specification of a function type includes any type qualifiers, the 
behavior is undefined."

3) Implement restrict on C++ references.

4) fix some locations for various C++ reference diagnostics.

Chris Lattner a21ad8058a Fix several bugs in array -> pointer decomposition.
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

Steve Naroff 257520b1b4 Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl).
- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

Chris Lattner 59a2594f3f rename Decl::CompatibleAlias -> ObjCCompatibleAlias.
Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
