Daniel Dunbar 56fdb6ae69 More #include cleaning
- Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

Steve Naroff 239255d2a6 Fix Sema::MergeVarDecl() to better handle type compatibility. The previous code was trying to handle arrays specially (which didn't work for pointers to array). Removed local helper function areEquivalentArrayTypes(), replacing it's use with the more general ASTContext::typesAreCompatible() predicate.
Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.

Steve Naroff 5bb8f2264b Fix issues with C "tentative" definitions.
- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.

Still some more work to do (forthcoming)...

Daniel Dunbar ffc29be83f Implement GNU asm-label extension support in CodeGen. This fixes
scimark2 on Darwin.

 - Added Sema support for asm-label on variables, which I forgot before.

 - Update CodeGen to use GlobalDeclMap to determine if static Decls
   require emission (instead of LLVM module name lookup). Important
   since the Decl name and the LLVM module name can differ.

 - <rdar://problem/6116729>

2008-08-05 16:28:08 +00:00
Daniel Dunbar 4983df37a7 Add more Parser/Sema support for GCC asm-label extension.
- ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

Chris Lattner 7adf076088 Finally fix PR2189. This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

Ted Kremenek 73295fab89 When constructing an ObjCIvarDecl object in Sema, provide its visibility up front instead of setting it afterwards.

Chris Lattner d7352d6801 minor cleanup to the actions interface to pass around SmallVectorImpl instead
of a specific smallvector size.

Fix protocol lists to pass down proper location info, so we get diagnostics
like this:

t.m:3:35: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^

Eli Friedman e6e0f23a29 Add code to make test/CodeGen/struct-init.c work correctly without the
pointer cast hack currently in isIntegerConstantExpr 
(in lib/AST/Expr.cpp).  Also removes an odd test that even gcc doesn't accept.

The reason the pointer cast hack is relevant here is that it makes Sema 
end up misinterpreting the relevant expression as a null pointer constant.

The reason for this patch is that I plan to remove the pointer cast hack 
sometime soon because it causes strange issues, especially in its 
current form; see my recent email to cfe-dev
"[PATCH] add constant expression evaluation to the AST and fix PR2413".

Eli Friedman 149614bfe7 Re-fix r51907 in a way which doesn't affect valid code. This essentially
moves the check for the invalid construct to a point where it doesn't 
affect other uses of isIntegerConstantExpr, and we can warn properly 
when the extension is used.  This makes it a bit more complicated, but 
it's a lot cleaner.

Steve, please tell me if this check is sufficient to handle the 
relevant system header.  I know it's enough to handle the testcase, but 
I don't know what exactly the original looks like.

Eli Friedman aee9e54dca Don't swap function decls, and add them to the scope as they are

Note that there is a need to look up the characteristics and 
declarations of a function associated with a particular name or decl, 
but the original swapping code doesn't solve it properly.

Argyrios Kyrtzidis c3b69ae815 Addition of TranslationUnitDecl to the AST:
-Added TranslationUnitDecl class to serve as top declaration context
-ASTContext gets a TUDecl member and a getTranslationUnitDecl() function
-All ScopedDecls get the TUDecl as DeclContext when declared at global scope

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 83a586ec19 Introduce support for finding class and enum names via ordinary name lookup in C++

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.

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 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.
