Anton Korobeynikov 18adbf5f07 Add new ABIArgInfo kind: Extend. This allows target to implement its own argument
zero/sign extension logic (consider, e.g. target has only 64 bit registers and thus
i32's should be extended as well).

Mike Stump cbc2bcaf17 As an optimization, we maintain a cache of generated
___Block_byref_id_object_dispose and ___Block_byref_id_object_copy
functions so that we can simply reuse instead of creating a new one.
Additionally, add an assert to ensure no one yet tries to align a
__block variable beyond the alignment of a pointer as the codegen is
incomplete.

Daniel Dunbar 4be99ff767 ABI handling: Fix nasty thinko where IRgen could generate an out-of-bounds read

Fariborz Jahanian 078cd52297 This patch fixes two bugs in the GNU Objective-C runtime implementation. One is a case in rethrowing exceptions where the C types don't match correctly (I already sent this patch to Daniel Dunbar, who found the bug, so it may have already been committed). The other fixes the case properties so that the methods generated as property accessors are added to the class structure correctly.

Mike Stump 2c002929b2 Fixup debug information for the location information for __block
variables.  For this to work, the backend needs to handle more complex
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 { }*))

Presently when selection finds something it doesn't understand, it
just avoids generating any information, which is safe, just
incomplete.  Radar 6867696

"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.

Daniel Dunbar e4f25b706b Reapply r69771, with updates & fixes:
Rework the shadow struct that is layed out for Objective-C classes.

 - Superclasses are now always laid out in their shadow structure at
   the first field.

 - Prior to this, the entire class heirarchy was flattened into a
   single structure which meant that alignment, padding, and bitfields
   were incorrect (the ASTRecordLayout was correct however, which
   meant our debug info didn't coincide with ivar offsets, for
   example).

 - This is still very suboptimal (for example, ivar are looked up
   recursively, but I believe the ivar layout itself is now at least
   close to correct.

 - <rdar://problem/6773388> error: objc[29823]: layout bitmap sliding
   backwards

2009-04-22 12:00:04 +00:00
Daniel Dunbar 7d4e1c5e4a Don't convert interface types (to structs) as part of CodeGenTypes.
- This has pros and cons, but for now the pros seem to significantly
   outway the con.

The con is that we will always need to cast in the runtime
implementation to a struct type, if we wish to access an interface
directly.

The pros are:
 - Avoid the cost of generating types which are used. Most
   manipulation of Objective-C objects is done through messages, and
   only the implementation of a class will directly access
   memory. Previously, we would convert the type even if it only
   appear as a function parameter, for example.

 - We don't need to worry about incomplete types, and
   UpdateCompletedType for interfaces is gone.

 - It becomes easier to narrow the interface to the shadow struct for
   Objective-C interfaces (so it can be eliminated).

Currently the runtimes still use the CodeGenTypes machinery to
generate the LLVM structure they need via ConvertTagDecl, but this can
eventually be replaced.

   Objective-C interface layout.
