2008-08-30Stub out CodeGenFunction::EmitObjCForCollectionStmt.Anders Carlsson
Add CodeGenFunction::EmitMemSetToZero and make AggExprEmitter::EmitAggregateClear use it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55573 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
2008-08-29Downgrade 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
2008-08-27Initial 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
2008-08-26Objective-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
2008-08-25Support __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
2008-08-23Implement 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
2008-08-23Trim 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

initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55180 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
2008-08-16Add 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
2008-08-11More #include cleaningDaniel Dunbar
- Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h - Moved Sema::getCurMethodDecl() out of line (dependent on ObjCMethodDecl via dyn_cast). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54629 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-04Add CodeGen support for indirect goto.Daniel Dunbar
- Follows emission scheme used by llvm-gcc, i.e. invent an id for each label whose address is taken and replace each indirect goto by a switch to each possible target. - Currently we emit a switch for each indirect goto instead of merging them as llvm-gcc does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54318 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-29Rework codegen emission of globalsDaniel Dunbar
- No (intended) functionality change. - Primary purpose is to clearly separate (lazy) construction of globals that are a forward declaration or tentative definition from those that are the final definition. - Lazy construction is now encapsulated in GetAddrOf{Function,GlobalVar} while final definitions are constructed in EmitGlobal{Function,Var}Definition. - External interface for dealing with globals is now limited to EmitGlobal and GetAddrOf{Function,GlobalVar}. - Also updated helper functions dealing with statics, annotations, and ctors to be private. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54179 91177308-0d34-0410-b5e6-96231b3b80d8

includes a small fix for constant string handling that should have been in the last patch (sorry!) and a hook for generating selectors (rest of this implementation to follow in the next patch)." Patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52681 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-17Change self/_cmd to be instances of ImplicitParamDecl instead of ParmVarDecl.Chris Lattner
Patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52422 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-17This patch is motivated by numerous strict-aliasing warnings when compilingTed Kremenek
clang as a Release build. The big change is that all AST nodes (subclasses of Stmt) whose children are Expr* store their children as Stmt* or arrays of Stmt*. This is to remove strict-aliasing warnings when using StmtIterator. None of the interfaces of any of the classes have changed (except those with arg_iterators, see below), as the accessor methods introduce the needed casts (via cast<>). While this extra casting may seem cumbersome, it actually adds some important sanity checks throughout the codebase, as clients using StmtIterator can potentially overwrite children that are expected to be Expr* with Stmt* (that aren't Expr*). The casts provide extra sanity checks that are operational in debug builds to catch invariant violations such as these. For classes that have arg_iterators (e.g., CallExpr), the definition of arg_iterator has been replaced. Instead of it being Expr**, it is an actual class (called ExprIterator) that wraps a Stmt**, and provides the necessary operators for iteration. The nice thing about this class is that it also uses cast<> to type-checking, which introduces extra sanity checks throughout the codebase that are useful for debugging. A few of the CodeGen functions that use arg_iterator (especially from OverloadExpr) have been modified to take begin and end iterators instead of a base Expr** and the number of arguments. This matches more with the abstraction of iteration. This still needs to be cleaned up a little bit, as clients expect that ExprIterator is a RandomAccessIterator (which we may or may not wish to allow for efficiency of representation). This is a fairly large patch. It passes the tests (except CodeGen/bitfield.c, which was already broken) on both a Debug and Release build, but it should obviously be reviewed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52378 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-13Basic support for volatile loads and stores. Stores the volatile Eli Friedman
qualifier in the lvalue, and changes lvalue loads/stores to honor the volatile flag. Places which need some further attention are marked with FIXMEs. Patch by Cédric Venet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52264 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-22Make CurFuncDecl more specific; I have some code I'm going to land in a Eli Friedman
bit that wants to use CurFuncDecl as a FunctionDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51402 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-22Move getAccessedFieldNo out of lib/AST/Expr.cpp intoDan Gohman
lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to use its own enum for visibility types instead of using llvm::GlobalValue::VisibilityTypes. These changes eliminate dependencies in the AST library on LLVM's VMCore library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51398 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-09Extend vector member references to include {.hi, .lo, .e, .o} which return aNate Begeman
vector of the same element type and half the width, with the high, low, even, and odd elements respectively. Allow member references to member references, so that .hi.hi gives you the high quarter of a vector. This is fairly convenient syntax for some insert/extract operations. Remove some unnecessary methods/types in the ExtVectorElementExpr class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50892 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-08Add basic support for the pic-* target triples and add support forChris Lattner

2008-04-15Remove FileVarDecl and BlockVarDecl. They are replaced by ↵Steve Naroff
VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl(). This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49748 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
