Daniel Dunbar 226bddaff1 IRgen/CGValue: Give MakeAddrLValue() an alignment argument, and eliminate old form of MakeAddr(). 
llvm-svn: 111723
 2010-08-21 03:58:45 +00:00

 2010-08-21 03:29:54 +00:00
Daniel Dunbar e50dda95ee IRgen/LValue: Add LValue::setNonGC instead of SetObjCNonGC, for consistency with isNonGC().

 2010-08-21 03:22:38 +00:00
Daniel Dunbar 93b00a98a3 IRgen: Add an LValue::MakeAddr variant which takes a type and uses that to build 
the qualifiers.

Also, add CodeGenFunction::MakeAddrLValue() helper function which passes in the
ASTContext.

Daniel Dunbar c75c8bd757 IRgen: Move the bit-field access type into CGBitFieldInfo, and change bit-field LValues to just store the base address of object containing the bit-field. 
llvm-svn: 100745
 2010-04-08 02:59:45 +00:00
Daniel Dunbar 196ea449ed IRgen: Move BitFieldIsSigned bit into CGBitFieldInfo. 
llvm-svn: 100513
 2010-04-06 01:07:44 +00:00
Daniel Dunbar dc406b8e92 IRgen: Move BitField LValues to just hold a reference to the CGBitFieldInfo. 
- Unfortunately, this requires some horrible code in CGObjCMac which always
   allocats a CGBitFieldInfo because we don't currently build a proper layout
   for Objective-C classes. It needs to be cleaned up, but I don't want the
   bit-field cleanups to be blocked on that.

 2009-09-24 22:25:38 +00:00
John McCall 8ccfcb51ee Refactor the representation of qualifiers to bring ExtQualType out of the 
Type hierarchy.  Demote 'volatile' to extended-qualifier status.  Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right;  many more remain.

 2009-08-20 17:02:02 +00:00
Fariborz Jahanian 88cc2340de Renamed ObjCKVCRefExpr to ObjCImplctSetterGetterRefExpr.

argument. Added DoxyGen comments. Still more work
to do in this area (WIP).

Mon P Wang acedf7768f Preserve address space information through member accesses, e.g., 
__attribute__((address_space(1))) struct {int arr[ 3 ]; }  *p1;
   ... = p1->arr[2];  // load from address space 1

emit two volatile loads for:
typedef __attribute__(( ext_vector_type(4) )) float float4;

float test(volatile float4 *P) {
  return P->x+P->y;
}

objects as __strong when attribute unspecified.

llvm-svn: 59654
 2008-11-19 18:38:10 +00:00

Daniel Dunbar cf56c2b7bd Add FIXME about potential problem in how property ref lvalues are handled. 
llvm-svn: 57743
 2008-10-17 23:02:24 +00:00
Daniel Dunbar 41cf9dedc6 Change CodeGen to emit calls using (RValue,Type) list: 
- Add CodeGenFunction::EmitAnyExprToTemp
   o Like EmitAnyExpr, but emits aggregates to a temporary location if
     none is available. Seems like this should be simpler (even aside
     from using first class aggregates).

 - Killed CodeGenFunction::EmitCallArg (just append the pair)

 - Conversion of RValues to actual call arguments is now isolated in
   CodeGenFunction::EmitCall.

llvm-svn: 55970
 2008-09-09 01:06:48 +00:00
Daniel Dunbar 9e22c0d317 Add special "property reference" CodeGen::LValue type for emitting 
Objective-C property references.
 - This handles property references "more correctly" but setters still
   don't work.

llvm-svn: 55534
 2008-08-29 08:11:39 +00:00
Daniel Dunbar d4f616b853 Move [LR]Value into CGValue.h
