2008-08-30Stub out CodeGenFunction::EmitObjCForCollectionStmt.Anders Carlsson
Add CodeGenFunction::EmitMemSetToZero and make AggExprEmitter::EmitAggregateClear use it. llvm-svn: 55573
2008-08-30Simplify some calls to Builder.CreateCallAnders Carlsson
llvm-svn: 55567
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. llvm-svn: 55561
2008-08-27Initial support for Obj-C dot-syntax for getters.Daniel Dunbar
llvm-svn: 55410
2008-08-23Drop a dead call to isConstantExpr()Daniel Dunbar
llvm-svn: 55244
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). llvm-svn: 55234
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 llvm-svn: 55223
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. llvm-svn: 54836
2008-08-11More #include cleaningDaniel Dunbar
- Remove internal uses of AST.h llvm-svn: 54628
2008-08-08update to make IRBuilder API change.Chris Lattner

2008-08-06Fix EmitNullInitializationToLValue for bitfield lvalues. Daniel Dunbar
- PR2643 llvm-svn: 54397
2008-08-04Finally fix PR2189. This makes a fairly invasive but important change toChris Lattner
move getAsArrayType into ASTContext instead of being a method on type. This is required because getAsArrayType(const AT), where AT is a typedef for "int[10]" needs to return ArrayType(const int, 10). Fixing this greatly simplifies getArrayDecayedType, which is a good sign. llvm-svn: 54317
2008-07-30Fix implicit initialization of structures.Daniel Dunbar
<rdar://problem/6113085> llvm-svn: 54237

2008-06-24"Support for Objective-C message sends which return structures. Also ↵Chris Lattner
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! llvm-svn: 52681
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. llvm-svn: 52378
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. llvm-svn: 52264
2008-05-27A few more cases for aggregate values.Eli Friedman
llvm-svn: 51596
2008-05-26Emit memmove, not memcpy, for structure copies; this is unfortunately Eli Friedman
required for correctness in cases of copying a struct to itself or to an overlapping struct (itself for cases like *a = *a, and overlapping is possible with unions). Hopefully, this won't end up being a perf issue; LLVM *should* be able to optimize memmove to memcpy in a lot of cases, and for small copies the generated code *should* be mostly comparable. (In reality, LLVM is currently horrible at optimizing memmove, but that's a bug, not a fundamental issue.) gcc currently generates wrong code; that's http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32667. llvm-svn: 51566
2008-05-22Change uses of llvm::Type::isFirstClassType to use the newDan Gohman
llvm::Type::isSingleValueType. Currently these two functions have the same behavior, but soon isFirstClassType will return true for struct and array types. Clang may some day want to use of isFirstClassType for some of these some day as an optimization, but it'll require some consideration. llvm-svn: 51446
2008-05-20Implement codegen for comma operator for structs.Eli Friedman
llvm-svn: 51304
2008-05-19Fix the emission of expressions like char a[10] = "asdf"; previously, Eli Friedman
they were causing bad code to be emitted. There are two fixes here: one makes sure we emit a string that is long enough, and one makes sure we properly handle string initialization in init lists. llvm-svn: 51259
2008-05-12Don't try to take the address of a bitfield; fixes PR2310.Eli Friedman

2008-04-04Fix PR2049, updating Eli's patch that fixes to mainline. This produces ↵Chris Lattner
incorrect code, but the codegen doesn't crash. I'll file a bugzilla for the AST being wrong. llvm-svn: 49226
2008-04-04Since isComplexType() no longer returns true for _Complex integers, the codeChris Lattner
generator needs to call isAnyComplexType(). This fixes PR1960. llvm-svn: 49220
2008-03-19simplify the clang codegen by using the new Builder.CreateStructGEP method.Chris Lattner
llvm-svn: 48534
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. llvm-svn: 48402
