Mike Stump 017460ab6c Implement a FIXME. This improves codegen just a tad.
llvm-svn: 83221
2009-10-01 22:29:41 +00:00
Douglas Gregor 369acf9304 CodeGen may see out-of-line declarations of the various special member
functions when they are explicitly declared, e.g., via a function
template specialization or explicit template instantiation
declaration. Don't try to synthesize bodies for the special member
functions in this case; rather, check whether we have an implicit
declaration and, if so, synthesize the appropriate function
body. Fixes PR5084.

Mike Stump 2e722b915c Improve debugging information for BlockDeclRefExpr. WIP. Given this
scheme, we can switch the previous scheme over to using this code
path.  There's a bit of simplifications yet to do as well.

Douglas Gregor bb3e12fc0b Handle C++ delete expressions when the overloaded delete operator is a
"usual deallocation function" with two arguments. CodeGen will have to
handle this case specifically, since the value for the second argument
(the size of the allocated object) may have to be computed at run
time.

Fixes the Sema part of PR4782.

The decl wasn't being passed down, which meant that function attributes were not

wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

directly in the AST.  The current thinking is to create these

This will let us do things like verify that tags match during
template instantation, as well as signal that an elaborated type
specifier was used for clients that actually care.

Optimally, the TypeLoc hierarchy should be adjusted to carry tag
location information as well.

This is a Type subclass that can hold a DeclaratorInfo* when we have type source info coming

passing/getting QualTypes, it does not participate in the type system semantics in any way.

EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo.

Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet.

David Chisnall 9f57c29053 Initial patch to support definitions of id and Class from headers in Objective-C code.
This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable.  The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa.

Eli Friedman 04fddf0d1f Fix for PR4721: adjust CodeGen and ASTContext so that we have a
consistent model for handling size expressions for VLAs.

The model is essentially as follows: VLA types own their associated
expression.  In some cases, we need to create multiple VLA types to 
represent a given VLA (for canonical types, or qualifiers on array types,
or type merging).  If we need to create multiple types based off of 
the same VLA declaration, we use the new refcounting functionality so they can 
all own the expression. The VLASizeMap in CodeGenFunction then uses the size
expression to identify the group of VLA types based off of the same original
declaration.

I'm not particularly attached to the VLA types owning the expression, 
but we're stuck with at least until someone comes up with a way 
to walk the VLA expressions for a declaration.

I did the parallel fix in ASTContext for DependentSizedArrayType, but I 
haven't really looked closely at it, so there might still be issues 
there.

I'll clean up the code duplication in ASTContext in a followup commit.

source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

Ted Kremenek e3fb4b6524 Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.
This method is intended to eventually replace the individual
Type::getAsXXXType<> methods.

The motivation behind this change is twofold:

1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of
them are basically copy-and-paste.

2) By centralizing the implementation of the getAs<Type> logic we can more
smoothly move over to Doug Gregor's proposed canonical type smart pointer
scheme.

Along with this patch:

a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>.
b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>.

This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-).

This patch also adds Type::isObjCBuiltinType().

This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small.

2009-07-11 00:57:02 +00:00
Steve Naroff 7cae42b07a This patch includes a conceptually simple, but very intrusive/pervasive change.
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.

This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.

By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. 

Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

This is simple enough, but then I thought it would be nice to make PrintingPolicy
get a LangOptions so that various things can key off "bool" and "C++" independently.
This spiraled out of control.  There are many fixme's, but I think things are slightly
better than they were before.

One thing that can be improved: CFG should probably have an ASTContext pointer in it,

Fariborz Jahanian b27c94199f This patch allows clang to generate code for declared properties on the GNU runtime. As with @synchronized, this requires some extra functions that are included with other libraries (not with the GNU runtime itself) and so will cause linker errors when these are not present.

Mike Stump 2c002929b2 Fixup debug information for the location information for __block

forms for locations.

A typical utterance would be:

        %forwarding = getelementptr %0* %use_by_ref, i32 0, i32 1               ; <i8**> [#uses=1]
        %0 = load i8** %forwarding              ; <i8*> [#uses=1]
        %1 = bitcast i8* %0 to %0*              ; <%0*> [#uses=1]
        %x = getelementptr %0* %1, i32 0, i32 4         ; <i32*> [#uses=1]
        %2 = bitcast i32* %x to { }*            ; <{ }*> [#uses=1]
        call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))

just avoids generating any information, which is safe, just

"This patch is a first pass at adding support for exceptions for the GNU runtime.  There are a few limitations at present:

- @synchronized() is not yet supported at all.  gcc currently emits calls to runtime library functions that don't exist for this directive.

- Only id @catch statements are currently working.  This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work.

- I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."

static __inline__ __attribute__((always_inline)) 
int bar(int x) { return 4; }
int main() { 
  int X = bar(4);
  printf("%d\n", X);
}

clang was not outputing any debug info for the body of main().  This is
because the backend is getting confused by the region_start/end that clang
is emitting for block scopes.  For now, just disable these (matching llvm-gcc),
this stuff is in progress of rework anyway.

Daniel Dunbar 98ba964e5c Don't allow clients to traverse into superclass synthesized properties
via CollectObjCIvars.
 - In places where we need them, we should have the implementation and
   access the properties through it.

This is a fairly substantial functionality change: 
 1. @encode no longer encodes synthesized ivars, ever.

 2. The ivar layout bitmap no longer encodes information for
    synthesized ivars in superclasses. Well, actually I had already
    broken that, but it is intentional now.

We are now differing substantially from llvm-gcc and gcc
here. However, in my opinion this fundamentally *must* work if
non-fragile classes are to work. Without this change, the result of
@encode and the ivar layout depend on the order that the
implementation is seen in a file (if it is in the same file with its
superclass). Since both scenarios should work the same, our behavior
is now consistent with gcc behavior as if an implementation is never
seen following an implementation of its superclass.

Note that #2 is only a functionality change when (A) an
implementation appears in the same translation unit with the
implementation of its superclass, and (B) the superclass has
synthesized ivars. My belief is that this situation does not occur in
practice.

I am not yet sure of the role/semantics of @encode when synthesized
ivars are present... it's use is fairly unsound in a non-fragile world.
