Chris Lattner ce8754edac remove the last of the non-lazy objc runtime functions for the 32-bit ABI, 
7 left for 64-bit ABI.

 2009-04-22 02:44:54 +00:00
Chris Lattner 0a696a42fe number of non-lazy runtime functions from 9 -> 4. 
llvm-svn: 69765
 2009-04-22 02:38:11 +00:00
Chris Lattner 095ac38f1c make message send functions lazy, we're down from 14 non-lazy functions to 9. 
llvm-svn: 69764
 2009-04-22 02:32:31 +00:00
Chris Lattner c6406dbf7f move more EH stuff to being lazily created. An empty .m file now 
produces just 14 dead "declares" in llvm ir instead of 19.

llvm-svn: 69763
 2009-04-22 02:26:14 +00:00
Chris Lattner a7c00b4c4c make try/catch objc runtime functions be lazily generated.

Daniel Dunbar d1148a7f72 Make sure to mark the interface as completed when we see an 
@implementation that closes a @class delcaration.
 - I don't know how to make a test case for this, but this strengthens
   the invariants that hold internally. The functionality change here
   is the edit to SemaDeclObjC.cpp.

Fariborz Jahanian f5fec02d0c More objc2's ivar layout bitmap. No change in functionality. 
llvm-svn: 69695
 2009-04-21 18:33:06 +00:00
Daniel Dunbar 9ebf9516af Kill ASTContext::[gs]etFieldForDecl, instead we just lookup things 
when we need them -- which is exactly what some code was already
doing!
 - No intended functionality change.

llvm-svn: 69648
 2009-04-21 01:19:28 +00:00
Daniel Dunbar e03f005d30 Assert on a few conditions that (I believe) should hold 
w.r.t. ASTContext::[gs]etFieldDecl, and the Field argument to
EmitObjCValueForIvar).

Fariborz Jahanian 80c9ce2c4a ObjC2's Ivar bitmap layout work. No change in functionality.

Daniel Dunbar e3f5cfc0b8 Move countInheritedIvars to within striking distance of 
GetClassSizeInfo

Reduce nesting in GetInterfaceDeclStructLayout.

Tweak some comments.

No functionality change.

Daniel Dunbar be1f26df5d Inline GetFirstIvarInRecord into sole caller. 
- No functionality change.

llvm-svn: 69582
 2009-04-20 07:18:49 +00:00
Daniel Dunbar 75e909f5e0 Set a bit in IMAGE_INFO to indicate that we don't contain any 
@synthesized ivars for superclasses.
 - <rdar://problem/6806371> [clang] Mark code without miscompiled
   @synthesized properties

llvm-svn: 69581
 2009-04-20 07:11:47 +00:00
Daniel Dunbar f5c18461e3 Lift out GetNamedIvarList. 
Drop uses of GetFirstInvarInRecord, instead we lookup the ivars we
know are in the record.
 - This is somewhat less efficient, but I need to detangle this code
   first...

llvm-svn: 69579
 2009-04-20 06:54:31 +00:00
Daniel Dunbar caec0238bc Don't emit ivar offsets for unnamed bit fields. 
Also, added assertion that the field matches what would be looked up.

llvm-svn: 69572
 2009-04-20 05:53:40 +00:00

Daniel Dunbar 554fd79b38 Lift GetClassSizeInfo out of GenerateClass, add a FIXME. 
- No functionality change.

 2009-04-19 23:41:48 +00:00
Chris Lattner b433b279f3 Fix rdar://6804402 - crash on objc implementations declared with 
@class but no implementation.  This was broken in all 3 runtime
impls.

llvm-svn: 69512
 2009-04-19 06:02:28 +00:00
Daniel Dunbar 9a7a78b0ae Fix bug in computation of ivar offsets for (adjacent) bitfields. 
- The confusing IRgen bitfield interface is partly to blame here;
   fixing the functional error for now, cleanups to the interface to
   follow.

llvm-svn: 69503
 2009-04-19 02:03:42 +00:00
Daniel Dunbar bf90b33665 Reuse ObjcIvarOffsetVariable instead of duplicating code. 
- No functionality change (but added a FIXME).

llvm-svn: 69496
 2009-04-19 00:44:02 +00:00
Daniel Dunbar a106052090 Remove some unnecessary complexity. 
- No functionality change.

llvm-svn: 69495
 2009-04-19 00:31:15 +00:00
Daniel Dunbar 508a7dda4a Fix a bug found by inspection, class/meta references could be emitted 
into the wrong section (they shared the same lookup table).

llvm-svn: 69433
 2009-04-18 08:51:00 +00:00
Chris Lattner 6fdd57cba8 fix a crash compiling code with its own definition of objc_assign_weak.

llvm-svn: 69392
 2009-04-17 22:12:36 +00:00
Daniel Dunbar 66b13dac0a Don't put msgrefs in used globals (in particular, we don't want 
no-dead-strip set on them).

llvm-svn: 69388
 2009-04-17 21:10:58 +00:00
Chris Lattner 10dae30049 Fix rdar://6800926 - crash compiling non-fragile _Bool bitfield ivar, 
the functional change here is changing ConvertType -> ConvertTypeForMem
so that we handle i1 fields properly as memory.

llvm-svn: 69361
 2009-04-17 17:46:19 +00:00
Fariborz Jahanian 68c4c61be8 Removed a no longer needed FIXME comment.

Fariborz Jahanian bcf548760e Category method synbols must be qualified by gategory name to 
match gcc's.

llvm-svn: 69305
 2009-04-16 18:34:20 +00:00
Daniel Dunbar 4b68d26a93 Don't use \01 in symbol name if unnecessary. 
- This was particularly bad since I fixed one instance of this name
   and not another, meaning we got an LLVM module with the same
   effective name in two different globals!

llvm-svn: 69205

Daniel Dunbar 24645c9ff4 Fix alignment on obj_msgrefs to match llvm-gcc. 
llvm-svn: 69199
 2009-04-15 19:04:46 +00:00
Daniel Dunbar e60aa05d34 Add test case for superrefs section (and make spacing consistent). 
llvm-svn: 69198
 2009-04-15 19:03:14 +00:00
Fariborz Jahanian f5e8ddd550 __objc_superrefs belongs to __DATA segment. 
llvm-svn: 69170
 2009-04-15 16:31:36 +00:00
Daniel Dunbar b25452a98e Tweaks to Objective-C metadata (32 & 64-bit) to match llvm-gcc. 
- Set alignment on property lists.
 - 32-bit:
   o Set section on property lists.
   o Fix section name for category class methods.
   o Fix symbol name for property lists.
   o Fix section name for class method.
   o Set alignment and section on class extension structure.
   o Set alignment on a number of things: instance variables, methods,
   method descriptions, the symbols structure.
 - 64-bit:
   o Fix section flags for protocol list.

I doubt most of these were problems in practice, but it is nice to
match llvm-gcc.

llvm-svn: 69132
 2009-04-15 02:56:18 +00:00
Daniel Dunbar 3241fae46c Set alignment on __cstring metadata variables to 1 (matching 
llvm-gcc).

llvm-svn: 69093
 2009-04-14 22:44:26 +00:00
Fariborz Jahanian 899e7eb6c7 Do not dead code strip global meta-data objects. 
This will match gcc's behavior in the arena.

llvm-svn: 69061

- No functionality change.

llvm-svn: 68987

Douglas Gregor bcced4ec31 Propagate the ASTContext to various AST traversal and lookup functions. 
No functionality change (really).

 2009-04-09 21:40:53 +00:00
Daniel Dunbar 8f28d01126 Implementation definition of interfaces with __objc_exception attribute. 
- Complete <rdar://problem/6635883> Support __objc_exception__
   attribute

llvm-svn: 68591
 2009-04-08 04:21:03 +00:00
Fariborz Jahanian 57eb2e021e Propagte -fvisibility to objc2's class symbols. 
llvm-svn: 68543
 2009-04-07 20:26:30 +00:00
Daniel Dunbar d7beeea228 Handle use side of __objc_exception__ attribute; when using an 
exception with this attribute we don't need to emit a weak definition
for the exception type information.

llvm-svn: 68513
 2009-04-07 06:43:45 +00:00
Daniel Dunbar 15894b791b Various fixes to symbols used for Obj-C x86_64 metadata. 
- Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

ivars.

 2009-04-06 18:30:00 +00:00
Chris Lattner dcceee734c Fix a couple of cases where Constant* pointers can dangle in 
ObjCNonFragileABITypesHelper by converting them to dynamic
getters.  This fixes a crash on rdar://6757213.  The others
should be converted over as well.

llvm-svn: 68445
 2009-04-06 16:53:45 +00:00
Fariborz Jahanian 38a5c9650e Fix up lookup rules for properties declared in 
objc's continuation class.
