llvm-svn: 69762
2009-04-22 02:15:23 +00:00
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.

llvm-svn: 69728
2009-04-21 21:41:56 +00:00
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).

Daniel Dunbar e3f5cfc0b8 Move countInheritedIvars to within striking distance of

Reduce nesting in GetInterfaceDeclStructLayout.

Tweak some comments.

No functionality change.

Daniel Dunbar be1f26df5d Inline GetFirstIvarInRecord into sole caller.

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.

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 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

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

llvm-svn: 69361

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
2009-04-15 19:52:32 +00:00
Daniel Dunbar 24645c9ff4 Fix alignment on obj_msgrefs to match llvm-gcc.
llvm-svn: 69199

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-svn: 68543
2009-04-07 20:26:30 +00:00
Daniel Dunbar d7beeea228 Handle use side of __objc_exception__ attribute; when using an

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.

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.

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: 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

Eli Friedman a374b68b5a Back out the patch in r66302, and re-fix it properly. We assume for

Daniel Dunbar 76b7acc49f First cut at zero-cost EH support.
