* This reworks some of the Diagnostic interfaces a bit to change how diagnosticsChris Lattner2008-11-181-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are formed. In particular, a diagnostic with all its strings and ranges is now packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a ton of random stuff. This has the benefit of simplifying the interface, making it more extensible, and allowing us to do more checking for things like access past the end of the various arrays passed in. In addition to introducing DiagnosticInfo, this also substantially changes how Diagnostic::Report works. Instead of being passed in all of the info required to issue a diagnostic, Report now takes only the required info (a location and ID) and returns a fresh DiagnosticInfo *by value*. The caller is then free to stuff strings and ranges into the DiagnosticInfo with the << operator. When the dtor runs on the DiagnosticInfo object (which should happen at the end of the statement), the diagnostic is actually emitted with all of the accumulated information. This is a somewhat tricky dance, but it means that the accumulated DiagnosticInfo is allowed to keep pointers to other expression temporaries without those pointers getting invalidated. This is just the minimal change to get this stuff working, but this will allow us to eliminate the zillions of variant "Diag" methods scattered throughout (e.g.) sema. For example, instead of calling: Diag(BuiltinLoc, diag::err_overload_no_match, typeNames, SourceRange(BuiltinLoc, RParenLoc)); We will soon be able to just do: Diag(BuiltinLoc, diag::err_overload_no_match) << typeNames << SourceRange(BuiltinLoc, RParenLoc)); This scales better to support arbitrary types being passed in (not just strings) in a type-safe way. Go operator overloading?! llvm-svn: 59502
* Start implementing support for @synchonized with the darwin ObjC API.Chris Lattner2008-11-151-0/+6

* Rework IRgen invariant w.r.t. current insert point.Daniel Dunbar2008-11-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - EmitStmt is no longer required to finish with a current insertion point defined (i.e. it does not need to make dummy blocks). Instead, it can clear the insertion point in the builder which indicates that the current insertion point is unreachable. - CodeGenFunction provides HaveInsertPoint and EnsureInsertPoint which respectively test if there is an insert point and ensure an insertion point exists (by making a dummy block). - Clearly mark functions in CodeGenFunction which can be called with no insertion point defined. Currently this is a limited set, and EmitStmt simply EnsureInsertPoint()s before emitting subsequent IR. Remove EmitDummyBlock, which is no longer needed. Clients who haven't already cleared the insertion point (typically via EmitBranch) can do so by hand. Remove isDummyBlock, which has effectively been renamed to HaveInsertPoint. The main thrust of this change is that we no longer have create dummy blocks just to destroy them a short time later in EmitBlock in the common case that there is no unreachable code following something like a goto. Additionally, this means that we are not using the hokey condition in isDummyBlock that a block without a name is a dummy block. Guess how well that works when we never emit block names! llvm-svn: 59089

* Use a unified return block.Daniel Dunbar2008-09-091-0/+5
| | | | | | | - For the time being this means our emitted code is somewhat worse, especially for aggregates. This will be fixed. llvm-svn: 56013

| | | | | | | | | | | | | | - 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

* Add Objective-C property setter support.Daniel Dunbar2008-08-301-12/+22
| | | | | | | | | | | | | | | | | | | | | | - Change Obj-C runtime message API, drop the ObjCMessageExpr arg in favor of just result type and selector. Necessary so it can be reused in situations where we don't want to cons up an ObjCMessageExpr. - Update aggregate binary assignment to know about special property ref lvalues. - Add CodeGenFunction::EmitCallArg overload which takes an already emitted rvalue. Add CodeGenFunction::StoreComplexIntoAddr. Disabled logic in Sema for parsing Objective-C dot-syntax that accesses methods. This code does not search in the correct order and the AST node has no way of properly representing its results. Updated StmtDumper to print a bit more information about ObjCPropertyRefExprs. llvm-svn: 55561
* Refactor handling of calls:Daniel Dunbar2008-08-301-2/+8
| | | | | | | | | | | | | | | | - Added CodeGenFunction::EmitCall which just takes the callee, return type, and a list of (Value*,QualType) pairs. - Added CodeGenFunction::EmitCallArg which handles emitting code for a call argument and turning it into an appropriate (Value*,QualType) pair. - Changed Objective-C runtime interface so that the actual emission of arguments for message sends is (once again) done in the code to emit a message send. No intended functionality change, this is prep work for better ABI support and for Objective-C property setter support. llvm-svn: 55560
* Add special "property reference" CodeGen::LValue type for emittingDaniel Dunbar2008-08-291-0/+6
| | | | | | | | Objective-C property references. - This handles property references "more correctly" but setters still don't work. llvm-svn: 55534

| | | | llvm-svn: 55410
* Objective-C @synthesize support.Daniel Dunbar2008-08-261-4/+86
| | | | | | | | | | | - 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. llvm-svn: 55365
* Fix Obj-C super sends inside class methods.Daniel Dunbar2008-08-251-6/+10
| | | | | | | - NeXT loads the super class at runtime; this required changing the runtime interface to pass more information down. llvm-svn: 55307
* Trim CGObjCRuntime::GenerateMessageSend[Super]Daniel Dunbar2008-08-231-29/+5
| | | | | | | | | | | | | | | | | | - 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 llvm-svn: 55223
* Move all Obj-C runtime interaction into CodeGenFunction.Daniel Dunbar2008-08-201-0/+5
| | | | | | | - Drop duplicate (and broken) code for sending messages. - Add EmitObjCProtocolExpr to CodeGenFunction. llvm-svn: 55024
* Add NeXT runtime support for generating methods.Daniel Dunbar2008-08-161-26/+12
| | | | | | | | | | | | | 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. llvm-svn: 54838
* Change ObjCRuntime::LookupClass -> GetClass, and now takes theDaniel Dunbar2008-08-161-9/+12
| | | | | | | | | | | | | 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). llvm-svn: 54833
* Change CGObjCRuntime methods to take appropriate clang Decls.Daniel Dunbar2008-08-151-27/+1
| | | | | | | | | - 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). llvm-svn: 54824
* Add GetAddrOfConstantCString methodDaniel Dunbar2008-08-131-1/+1
| | | | | | | | | | | | | | | | | | - 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> llvm-svn: 54768
* Drop Sender from GenerateMessageSend*Daniel Dunbar2008-08-121-3/+2

* Add ObjC constant string support for NeXT.Daniel Dunbar2008-08-121-3/+4
| | | | | | | | | | 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. llvm-svn: 54659
* Change CodeGenModule to only create ObjC runtime for ObjC filesDaniel Dunbar2008-08-111-7/+7
| | | | | | | - Changed CodeGenModule::getObjCRuntime to return reference. - Added CodeGenModule::hasObjCRuntime predicate. llvm-svn: 54645
* More #include cleaningDaniel Dunbar2008-08-111-4/+0
| | | | | | | | | | | - 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. llvm-svn: 54632
* More #include cleaningDaniel Dunbar2008-08-111-0/+2
| | | | | | | | - Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h - Moved Sema::getCurMethodDecl() out of line (dependent on ObjCMethodDecl via dyn_cast). llvm-svn: 54629
