2008-09-27Bug fix, codegen @catch(id<X> ...) acceptably.Daniel Dunbar
- This should be rejected by sema (IMHO) but that needs some investigation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56756 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-27Simplify generate code for exceptions: Daniel Dunbar
- There is no need to branch on the rethrow variable to determine if we need to call objc_exception_try_exit. We know whether an exception was thrown, so just branch to a different target if we want to skip the try_exit. This is a slight semantic departure from gcc, but only for throwing nil, which is undefined (and for which gcc emits broken code). - Also fixes a bug in current code which was calling try_exit too many times when an exception was uncaught (but there were some handlers). Fix bug introduced in prev. commit, the type of the @catch parameter was uninitialized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56754 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-27Bug fix, make sure to initialize exception object (to rethrow) evenDaniel Dunbar
when there are no @catch blocks. Also, eliminated unneeded alloca for the rethrow object. Also, avoid generating code to rethrow exception if the exception will trivially always be caught. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56751 91177308-0d34-0410-b5e6-96231b3b80d8

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

2008-09-09Change 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

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

2008-08-26Objective-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

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

2008-08-21Preliminary support for Obj-C classes in NeXT runtime.Daniel Dunbar
