Fariborz Jahanian dac14a7159 - Minor change to dump of ivar layout map. 
- Temporarily undef'ed __OBJC2__ in nonfragile objc abi mode
  as it was forcing ivar synthesis in a certain project which clang
  does not yet support.

although they aren't currently).
 - No functionality change.

Fariborz Jahanian 03676f557c correct bitfield ivar offset in ivar meta-data. 
(objc abi specific).

llvm-svn: 66345
 2009-03-07 19:43:20 +00:00
Mike Stump a6ca334389 Fixup our uses of various linkages to match how llvm now works. I think they are all 
correct, but an extra set of ObjC eyes would be good.

llvm-svn: 66342
 2009-03-07 16:33:28 +00:00
Eli Friedman a374b68b5a Back out the patch in r66302, and re-fix it properly. We assume for 
performance that the type of the returned llvm::Value for an expression 
matches the converted type of the clang::Expr; mismatches will cause all
sorts of errors and silent miscompilations.

llvm-svn: 66321

 2009-03-04 18:21:39 +00:00
Steve Naroff 371b8fb4c3 Fix <rdar://problem/6640991> Exception handling executes wrong clause (Daniel, please verify). 
Also necessary to fix:

<rdar://problem/6632061> [sema] non object types should not be allowed in @catch statements
<rdar://problem/6252237> [sema] qualified id should be disallowed in @catch statements

 2009-03-03 19:52:17 +00:00
Daniel Dunbar 76b7acc49f First cut at zero-cost EH support. 
- Still manually generates the EH code; the parts related to cleanup
   need to be integrated into the cleanup stack (for proper
   interaction with VLAs, etc.).

 - Some differences vs gcc in corner cases; I believe our behavior is
   correct but need to verify/file bugs vs gcc.

llvm-svn: 65809
 2009-03-02 06:08:11 +00:00
Daniel Dunbar 7a38ce4f88 Make sure to invoke (not call) to objc_exception_throw if necessary.

llvm-svn: 65762
 2009-03-01 04:51:18 +00:00
Daniel Dunbar b1559a4499 Obj-C non fragile ABI: Add GetInterfaceEHType for getting the Obj-C 
exception typeinfo metadata, and a few other EH related types/functions.
 - No functionality change.

llvm-svn: 65761

llvm-svn: 65759
 2009-03-01 04:28:32 +00:00
Fariborz Jahanian bac73acc24 Obscure code gen bug related to sending 
message to 'super' in a class method declared in
cateogy (darwin specific).

llvm-svn: 65709
 2009-02-28 20:07:56 +00:00
Fariborz Jahanian cd073cc2e9 Alignment of pointers in __objc_classlist must be on their 
natural alignment. Otherwise, the excess hole confuses the
objc2 runtime (this is darwin specific).

llvm-svn: 65666
 2009-02-28 00:54:00 +00:00
Fariborz Jahanian ec3385733a Couple of meta-data segments were wrong. This patch fixes them. 
llvm-svn: 65578
 2009-02-26 22:30:39 +00:00

the symbol for the root meta-data.

llvm-svn: 65548
 2009-02-26 18:23:47 +00:00
Fariborz Jahanian 240f2b7851 patch for two things. 
make sure objc2's nonfragile abi is enacted for Leopard too.
add -fobjc-gc-only flag to the image_info symbol.

llvm-svn: 65413
 2009-02-24 23:34:44 +00:00
Fariborz Jahanian 6fe4306195 Set flag for -fobjc-gc in IMAGE_INFO variable. 
llvm-svn: 65387
 2009-02-24 21:08:09 +00:00
Daniel Dunbar 0b0dcd987d Some initial Obj-C zero cost EH support. 
- Only handles cases with @try with no @catch blocks, and there are a
   number of problems with the implementation. Nevertheless, this is
   good enough to handled @synchronized correctly, and some other
   basic uses.

llvm-svn: 65378
 2009-02-24 07:47:38 +00:00
Daniel Dunbar 94ceb61574 Fix two @synchronized bugs found by inspection: the expression to sychronize on should only be evaluated once, and it is evaluated outside the cleanup scope. 
Also, lift SyncEnter and SyncExit up in nervous anticipation of x86-64
zero cost EH.

llvm-svn: 65362
 2009-02-24 01:43:46 +00:00
Fariborz Jahanian 0f466c746f More objc's gc ir-gen stuff.

Daniel Dunbar d73ea816af assert/ErrorUnsupported in unimplemented stub functions instead of 
miscompiling.

 2009-02-16 18:48:45 +00:00
Daniel Dunbar 8de90f0a92 Obj-C non-fragile ABI: Fix types of a few globals; these were not 
creating valid LLVM structures (although they work fined).

llvm-svn: 64580
 2009-02-15 07:36:20 +00:00
Fariborz Jahanian 35afdfc36e Fixed a bad ir-gen bug which caused a dejagnu test to fail. 
Now we are pretty close to be in sync with objc's classic 
abi when it comes to passing dejagnu objc executable tests.

llvm-svn: 64569
 2009-02-14 21:25:36 +00:00
Fariborz Jahanian 99bed6fd21 Fixed a problem caused by foreward @class use 
which consequently caused a Seg fault. during meta-data
generation. It also addresses an issue related to
late binding of newly synthesize ivars (when we support it).
