2008-08-29Downgrade a number of FIXME asserts to ErrorUnsupported.Daniel Dunbar
- Notably VLAs git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55544 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-29Add special "property reference" CodeGen::LValue type for emittingDaniel Dunbar
Objective-C property references. - This handles property references "more correctly" but setters still don't work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55534 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Fix double-free error with sizeof applied to VLA types.Daniel Dunbar
- PR2727. Also, fix warning in CodeGenTypes for new BlockPointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55479 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28NeXT: Emit mostly-correct property type encoding.Daniel Dunbar
- Added ASTContext::getObjCEncodingForPropertyDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55461 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Initial support for Obj-C dot-syntax for getters.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55410 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27NeXT: Refactor protocol method metadata emission.Daniel Dunbar
Also, fix category protocol list metadata. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55405 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-26NeXT: Emit correct properties for category.Daniel Dunbar
- Was emitting duplicates of class properties instead of the category properties. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55395 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-26NeXT: Emit metadata for synthetsized properties.Daniel Dunbar
Also, fix method lookup to not use LLVM module symbol table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55390 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-26Objective-C @synthesize support.Daniel Dunbar
- Only supports simple assignment and atomic semantics are ignored. - Not quite usable yet because the methods do not actually get added to the class metadata. - Added ObjCPropertyDecl::getSetterKind (one of Assign, Copy, Retain). - Rearrange CodeGenFunction so synthesis can reuse function prolog / epilog code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55365 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Do typechecking and codegen for K&R-style function declarations Eli Friedman
correctly. Not a regression, but made more obvious by my recent fix which made function type compatibility checking a bit more strict. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55339 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Support __PRETTY_FUNCTION__ and friends in Obj-C methods.Daniel Dunbar
Add CodeGenFunction::EmitUnsupportedLValue - Gives error and returns undef value. Swap some asserts() over to using EmitUnsupportedLValue - Rumor has it users (and even some developers) prefer carat diagnostics to backtraces. - Works better in Release-Asserts to boot. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55328 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Change another is-a-pointer check to check in terms of LLVM type.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55312 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Do is-a-pointer checks in terms of LLVM types inDaniel Dunbar
EmitScalarConversion(). - Important for allowing Obj-C void * to id<X> casts and so on. - Not sure about this fix however, perhaps Type should understand that id is effectively a pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55311 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Fix Obj-C super sends inside class methods.Daniel Dunbar
- NeXT loads the super class at runtime; this required changing the runtime interface to pass more information down. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55307 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Name struct types generated for Obj-C classes.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55304 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Use DenseMap on IdentifierInfo instead of StringMap.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55303 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25NeXT: Emit symbols used to manage linking of Obj-C classes.Daniel Dunbar
- This ensures that references to undefined classes cause link errors. - NOTE: This relies on platform specific asm directives currently, this should be factored out. Also, don't emit a SYMBOLS metadata entry if there are no symbols. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55302 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Handle emitting __builtin_huge_valf as a constant expr.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55299 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Make code generation of ivar ref exprs more like member exprs.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55298 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Handle static variables inside obj-c methods.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55297 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-24Convert qualified interface types correctly.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55287 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Handle static initializers in Objective-C++ methods.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55250 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Add CodeGen support for CXXZeroInitValueExpr.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55249 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Drop a dead call to isConstantExpr()Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55244 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23NeXT: Clean up constant CFString handling.Daniel Dunbar
- Use CodeGenModule::GetAddrOfConstantCFString Some tweaks of CodeGenModule::GetAddrOfConstantCFString git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55243 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Implement Obj-C ivar references to aggregates.Daniel Dunbar
Implement Obj-C lvalue message sends (aggregate returns). Update several places to emit more precise ErrorUnsupported warnings for currently unimplemented Obj-C features (main missing chunks are property references, Obj-C exception handling, and the for ... in syntax). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55234 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23NeXT: Fix message sends which return structures.Daniel Dunbar
- Simplify the sending code a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55232 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23NeXT: Implement super message sends.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55225 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Trim CGObjCRuntime::GenerateMessageSend[Super]Daniel Dunbar
- Returns an RValue. - Reduced to only taking the CodeGenFunction, Expr, and Receiver. - Becomes responsible for emitting the arguments. Add CodeGenFunction::EmitCallExprExt - Takes optional extra arguments to insert at the head of the call. - This allows the Obj-C runtimes to call into this and isolates the argument and call instruction generation code to one place. Upshot is that we now pass structures (more) correctly. Also, fix one aspect of generating methods which take structure arguments (for NeXT). This probably needs to be merged with the SetFunctionAttributes code in CodeGenModule.cpp git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55223 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Move [LR]Value into CGValue.hDaniel Dunbar
- No (intended) functional change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55221 91177308-0d34-0410-b5e6-96231b3b80d8

initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55180 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-21NeXT: Emit [meta]class protocol references.Daniel Dunbar
Updated ObjCProtocolDecl::protocol_iterator to match that of ObjCInterfaceDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55143 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-21Preliminary support for Obj-C classes in NeXT runtime.Daniel Dunbar
- Functional for simple cases but there are some glaring omissions (protocols, properties, and other language extensions). - The code needs a fair bit of cleaning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55108 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-20Move all Obj-C runtime interaction into CodeGenFunction.Daniel Dunbar
- Drop duplicate (and broken) code for sending messages. - Add EmitObjCProtocolExpr to CodeGenFunction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55024 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-18Add ExplicitCastExpr to replace the current CastExpr, and have ↵Argyrios Kyrtzidis
ImplicitCastExpr and ExplicitCastExpr derive from a common base class (CastExpr): Expr -> CastExpr -> ExplicitCastExpr -> ImplicitCastExpr git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54955 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16Add NeXT runtime support for generating methods.Daniel Dunbar
Change CodeGenFunction::EmitParmDecl to take either a ParmVarDecl or an ImplicitParamDecl. Drop hasAggregateLLVMType from CodeGenModule.cpp (use version in CodeGenFunction). Change the Objective-C method generation to use EmitParmDecl for implicit parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54838 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16Add CodeGen support for AddrLabelExpr in initializers.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54837 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16Change WarnUnsupported to ErrorUnsupported (in name and in practice).Daniel Dunbar
- We are beyond the point where this shows up often and when it does generating miscompiled files is bad. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54836 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16Change ObjCRuntime::LookupClass -> GetClass, and now takes theDaniel Dunbar
ObjCInterfaceDecl. Change ObjCRuntime::GenerateMessageSendSuper to take the ObjCInterfaceDecl for the super class, instead of just its name. Change EmitObjCMessageExpr to make the right runtime calls for super sends in class methods (i.e. a super send with the class object as the receiver). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54833 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-15Clean up CodeGenModule interface.Daniel Dunbar
- Add CodeGenModule::EmitTopLevelDecl which uses switch on kind instead of ugly & slow dyn_cast chains. - Drop some simple forwarding methods into the ObjC runtime. - Privatize appropriate methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54827 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-15Change CGObjCRuntime methods to take appropriate clang Decls.Daniel Dunbar
- This is in prep for implementation class support for the NeXT runtime, for which the existing methods don't provide enough information (and additionally make too many assumptions about how things should be emitted). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54824 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-15Infinite loops considered harmful. Daniel Dunbar
- Thanks Thomas git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54818 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Update some isIntegerConstantExpr uses to useDaniel Dunbar
getIntegerConstantExprValue where appropriate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54771 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Add GetAddrOfConstantCString methodDaniel Dunbar
- Returns addr of constant for argument + '\0'. - I couldn't think of a better name. - Move appropriate users of GetAddrOfConstantString to this. Rename getStringForStringLiteral to GetStringForStringLiteral. Add GetAddrOfConstantStringFromLiteral - This combines GetAddrOfConstantString and GetStringForStringLiteral. This method can be, but is not yet, more efficient. Change GetAddrOfConstantString to not add terminating '\0' - <rdar://problem/6140956> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54768 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Implement Obj-C protocol metadata generation for NeXT.Daniel Dunbar
- Near complete, only properties are missing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54715 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Change ObjCRuntime GenerateProtocol[Ref] methods to takeDaniel Dunbar
ObjCProtocolDecl directly. Implement CodeGen support for forward protocol decls (no-ops are so nice to implement). Also moved CGObjCRuntime.h out of CodeGenModule.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54709 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-12Emit OBJC_MODULE_INFO and OBJC_SYMBOLS metadataDaniel Dunbar
- Matches llvm-gcc and seem to be expected by otool. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54669 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-12Drop Sender from GenerateMessageSend*Daniel Dunbar
- Was unused and generated a unnecessary load of self (missed file) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54668 91177308-0d34-0410-b5e6-96231b3b80d8
