2008-09-10Add CodeGenTypes::GetFunctionType overload for getting the effectiveDaniel Dunbar
type of a call. Change NeXT runtime to use this instead of trying to bitcasting internally (which doesn't respect the ABI). Fix subtle bug, use of ConvertTypeRecursive instead of ConvertType is bad inside GetFunctionType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56050 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-10Move FunctionType conversion into CGCall.cpp:Daniel Dunbar
- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo. - Updated Obj-C runtimes to use this instead of rolling the llvm::FunctionType by hand. - Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}. Add ABIArgInfo class to encapsulate ABI decision of how to lower types to LLVM. - Will move to target sometime soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56047 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-10Tweak CGCall functions again:Daniel Dunbar
- Realized these functions will eventually need access to more data, moved to CodeGenModule. Eventually they should probably live together in some other helper class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56039 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Add CodeGenFunction::ReturnTypeUsesSretDaniel Dunbar
- Hook so NeXT runtime doesn't depend on ABI. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56034 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-09Change CodeGen to emit calls using (RValue,Type) list:Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55970 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-05Change struct forward declarations and definitions to use unique ↵Ted Kremenek
RecordDecls, as opposed to creating a single RecordDecl and reusing it. This change effects both RecordDecls and CXXRecordDecls, but does not effect EnumDecls (yet). The motivation of this patch is as follows: - Capture more source information, necessary for refactoring/rewriting clients. - Pave the way to resolve ownership issues with RecordDecls with the forthcoming addition of DeclGroups. Current caveats: - Until DeclGroups are in place, we will leak RecordDecls not explicitly referenced by the AST. For example: typedef struct { ... } x; The RecordDecl for the struct will be leaked because the TypedefDecl doesn't refer to it. This will be solved with DeclGroups. - This patch also (temporarily) breaks CodeGen. More below. High-level changes: - As before, TagType still refers to a TagDecl, but it doesn't own it. When a struct/union/class is first referenced, a RecordType and RecordDecl are created for it, and the RecordType refers to that RecordDecl. Later, if a new RecordDecl is created, the pointer to a RecordDecl in RecordType is updated to point to the RecordDecl that defines the struct/union/class. - TagDecl and RecordDecl now how a method 'getDefinition()' to return the TagDecl*/RecordDecl* that refers to the TagDecl* that defines a particular enum/struct/class/union. This is useful from going from a RecordDecl* that defines a forward declaration to the RecordDecl* that provides the actual definition. Note that this also works for EnumDecls, except that in this case there is no distinction between forward declarations and definitions (yet). - Clients should no longer assume that 'isDefinition()' returns true from a RecordDecl if the corresponding struct/union/class has been defined. isDefinition() only returns true if a particular RecordDecl is the defining Decl. Use 'getDefinition()' instead to determine if a struct has been defined. - The main changes to Sema happen in ActOnTag. To make the changes more incremental, I split off the processing of enums and structs et al into two code paths. Enums use the original code path (which is in ActOnTag) and structs use the ActOnTagStruct. Eventually the two code paths will be merged, but the idea was to preserve the original logic both for comparison and not to change the logic for both enums and structs all at once. - There is NO CHAINING of RecordDecls for the same RecordType. All RecordDecls that correspond to the same type simply have a pointer to that type. If we need to figure out what are all the RecordDecls for a given type we can build a backmap. - The diff in CXXRecordDecl.[cpp,h] is actually very small; it just mimics the changes to RecordDecl. For some reason 'svn' marks the entire file as changed. Why is CodeGen broken: - Codegen assumes that there is an equivalence between RecordDecl* and RecordType*. This was true before because we only created one RecordDecl* for a given RecordType*, but it is no longer true. I believe this shouldn't be too hard to change, but the patch was big enough as it is. I have tested this patch on both the clang test suite, and by running the static analyzer over Postgresql and a large Apple-internal project (mix of Objective-C and C). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55839 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-05Remove "NextDecl" from RecordDecl. This change touches many files that ↵Ted Kremenek
where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration. The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55821 91177308-0d34-0410-b5e6-96231b3b80d8

references (to match gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55760 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-03Fix ObjCPropertRefExpr to be able to encode all the information forDaniel Dunbar
uses which refer to methods not properties. - Not yet wired in Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55681 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55583 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-30Add Objective-C property setter support.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55561 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-30Refactor handling of calls:Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55560 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
2008-08-27NeXT: 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
2008-08-25Fix 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
2008-08-25NeXT: 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
2008-08-23NeXT: 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
2008-08-23NeXT: 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

2008-08-21NeXT: Emit [meta]class protocol references.Daniel Dunbar

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
2008-08-16Add 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 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
2008-08-15Change 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
2008-08-13Implement Obj-C protocol metadata generation for NeXT.Daniel Dunbar

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

- Wired to -fnext-runtime and -fgnu-runtime options. - Defaults to GNU, no autoselection for NeXT. Emit NeXT OBJC_IMAGE_INFO marker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54651 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
