* Support va_arg on _Complex.Daniel Dunbar2009-02-101-0/+18

* Introduce a new expression node, ImplicitValueInitExpr, thatDouglas Gregor2009-01-291-0/+6
| | | | | | | | | | | | | represents an implicit value-initialization of a subobject of a particular type. This replaces the (ab)use of CXXZeroValueInitExpr within initializer lists for the "holes" that occur due to the use of C99 designated initializers. The new test case is currently XFAIL'd, because CodeGen's ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be taught to value-initialize when it sees ImplicitValueInitExprs. llvm-svn: 63317

* 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

* Add CodeGenFunction::EmitBranch.Daniel Dunbar2008-11-111-2/+2
| | | | | | | - Emits an unconditional branch, with extra logic to avoid generating spurious branches out of dummy blocks. llvm-svn: 59037

* Add Objective-C property setter support.Daniel Dunbar2008-08-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | - 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

* This patch is motivated by numerous strict-aliasing warnings when compilingTed Kremenek2008-06-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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
