I could probably be convinced that the ObjC 'needs GC' bit should

Validated by nightly-test runs on x86 and x86-64 darwin, including after
...
self-host. Hopefully these results hold up on different platforms.
I tried to keep the GNU ObjC runtime happy, but it's hard for me to test.
Reimplement how clang generates IR for exceptions. Instead of creating new
invoke destinations which sequentially chain to the previous destination,
push a more semantic representation of *why* we need the cleanup/catch/filter
behavior, then collect that information into a single landing pad upon request.
Also reorganizes how normal cleanups (i.e. cleanups triggered by non-exceptional
control flow) are generated, since it's actually fairly closely tied in with
the former. Remove the need to track which cleanup scope a block is associated
with.
Document a lot of previously poorly-understood (by me, at least) behavior.
The new framework implements the Horrible Hack (tm), which requires every
landing pad to have a catch-all so that inlining will work. Clang no longer
requires the Horrible Hack just to make exceptions flow correctly within
a function, however. The HH is an unfortunate requirement of LLVM's EH IR.

If a function definition has any sort of weak linkage, its static local

variables should have that linkage. Otherwise, its static local

fixes that and also gives better linkage than 'weak' when merging is required.

Avoid generation of dead code in a few more situations.
...
- Emit variable declarations as "simple", we want to avoid forcing the creation
of a dummy basic block, but still need to make the variable available for
later use.
- With that, we can now skip IRgen for other unreachable statements (which
don't define a label).
- Anders, I added two fixmes on calls to EmitVLASize, can you check them?

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

- Exposed quite a few Sema issues and a CodeGen crash.
- See FIXMEs in test case, and in SemaDecl.cpp (PR3983).
I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.
