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

2008-08-21Preliminary 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

- 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

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

2008-08-16Change 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

2008-08-13Add 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

2008-08-13Change 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

2008-08-12Add ObjC constant string support for NeXT.Daniel Dunbar
Changed CGObjCRuntime::GenerateConstantString interface to take std::string instead of char* and size. Change ObjC functions which call on GenerateConstantString to bitcast result to appropriate type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54659 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-11Add -fexceptions to DriverDaniel Dunbar
- Maps to LangOptions.Exceptions - Currently always off, should autoselect based on language. Update CodeGen to set unwind attribute on functions definitions based on LangOptions.Exceptions. - Still need to set attributes appropriately on calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54643 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-11More #include cleaningDaniel Dunbar
- Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54632 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-10Back out r54608 (inline string literals were getting an extra '\0')Daniel Dunbar
temporarily, I assumed GetAddrForConstantString literal was being used consistently but it doesn't look like it is. Factored out a CodeGenModule::getStringForStringLiteral which handles extracting a std::string for the bytes of a StringLiteral, padded to match the type. Update EmitLValue to use getStringForStringLiteral, this was previously not padding strings correctly. Good thing we only emit strings in 4 different places! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54621 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-06Fix bitfield accesses which straddle the boundary of the underlyingDaniel Dunbar
type. - This generates somewhat less optimal code than before but this is not hard to rectify once stable (at the cost of slightly more complex code). - This currently always uses little-endian ordering of the bitfield. - This breaks the CodeGen/bitfield.c test because it was grepping for hard-coded assembly instructions. Will fix once a better test case is constructed (hard to do without execution). - This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c and Regression/C/PR1386.c from the test suite. - <rdar://problem/6085090>, <rdar://problem/6094169> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54395 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-06Fix CodeGen of pointer arithmetic in compound assignment statements.Daniel Dunbar
- Changed EmitSub to work on all cases (arithmetic, ptr - int, ptr - ptr) so that implementation matches that of other operators. - Modify EmitCompoundAssign to compute and perform the appropriate casts of left, right, and result types for the assorted pointer arithmetic cases. - Fix EmitSub (ptr - int) case to negate the rhs *after* extension. This is critical when the rhs is unsigned (and needs extension). - This fixes cfrac. - <rdr://6115726> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54392 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-06Implement GNU asm-label extension support in CodeGen. This fixesDaniel Dunbar
scimark2 on Darwin. - Added Sema support for asm-label on variables, which I forgot before. - Update CodeGen to use GlobalDeclMap to determine if static Decls require emission (instead of LLVM module name lookup). Important since the Decl name and the LLVM module name can differ. - <rdar://problem/6116729> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54388 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-05Change CodeGen of global decls to key off of the name (instead ofDaniel Dunbar
having multiple bindings from all the possible decls which conceptually map to the same global). - This eliminates CodeGen depending on the LLVM module for name lookup. - This also eliminates the need for ReplaceMapValuesWith (hurrah). - This handles lookups for FunctionDecls correctly in the presence of aliases, this was previously broken. - WIP: Can still clean up & unify variable and function emission. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54382 91177308-0d34-0410-b5e6-96231b3b80d8
