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.

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.

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.

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!

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.

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).

Daniel Dunbar 729df96bf5 Avoid use of magic \01 prefix when unneeded. 
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.

Daniel Dunbar 8f28d01126 Implementation definition of interfaces with __objc_exception attribute. 
- Complete <rdar://problem/6635883> Support __objc_exception__
   attribute

llvm-svn: 68591

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.

Fariborz Jahanian bc3c77b881 Fixed visibility issues related to objc2's synthesized 
ivars.

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.

 2009-04-02 18:44:20 +00:00
Fariborz Jahanian 78be1651e2 Nonfragile ivar synthesis with property is in a continuation 
class.

Steve Naroff e14b368fa9 More "prep" work for handling UTF16 CFString. 
Patch by Jean-Daniel Dupas. Thanks!

 2009-04-01 13:55:36 +00:00
Chris Lattner 3088a31e96 remove ASTContext::buildObjCInterfaceType, which breaks canonical 
types.  It is no longer needed now that the code generator 
re-lays-out interfaces if they are defines after being laid out
from a forward decl.

llvm-svn: 68194
 2009-04-01 06:23:52 +00:00
Fariborz Jahanian 63a224ad59 ir-gen support for nonfragile abi's synthesized ivars.

 2009-03-31 18:11:23 +00:00
Fariborz Jahanian 3254a6f94c More toward nonfragile abi's synthesized ivars. 
llvm-svn: 68115
 2009-03-31 17:00:52 +00:00
Steve Naroff 66afeb5968 Some "prep" work for handling ObjC @-string constants that contain UTF-8. No functionality change. 
Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).

llvm-svn: 68114
 2009-03-31 16:53:37 +00:00
Chris Lattner 5b36ddb1ad fill in temporary smallvectors instead of vectors for performance.

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.
