* Introduce a new expression node, ImplicitValueInitExpr, thatDouglas Gregor2009-01-291-3/+3
| | | | | | | | | | | | | 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

* Improvements to code-generation and semantic analysis of designatedDouglas Gregor2009-01-281-5/+10
| | | | | | | | | | | | initializers. - We now initialize unions properly when a member other than the first is named by a designated initializer. - We now provide proper semantic analysis and code generation for GNU array-range designators *except* that side effects will occur more than once. We warn about this. llvm-svn: 63253
* Code generation support for C99 designated initializers.Douglas Gregor2009-01-281-13/+5
| | | | | | | | | | | | | | | | | | | | The approach I've taken in this patch is relatively straightforward, although the code itself is non-trivial. Essentially, as we process an initializer list we build up a fully-explicit representation of the initializer list, where each of the subobject initializations occurs in order. Designators serve to "fill in" subobject initializations in a non-linear way. The fully-explicit representation makes initializer lists (both with and without designators) easy to grok for codegen and later semantic analyses. We keep the syntactic form of the initializer list linked into the AST for those clients interested in exactly what the user wrote. Known limitations: - Designating a member of a union that isn't the first member may result in bogus initialization (we warn about this) - GNU array-range designators are not supported (we warn about this) llvm-svn: 63242

* add codegen support to union castsNuno Lopes2009-01-151-1/+14

* Prevent a segfault for vaarg expressions on unsupported architectures.Sebastian Redl2009-01-091-2/+4
| | | | llvm-svn: 62008
* Unifies the name-lookup mechanisms used in various parts of the ASTDouglas Gregor2008-12-111-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and separates lexical name lookup from qualified name lookup. In particular: * Make DeclContext the central data structure for storing and looking up declarations within existing declarations, e.g., members of structs/unions/classes, enumerators in C++0x enums, members of C++ namespaces, and (later) members of Objective-C interfaces/implementations. DeclContext uses a lazily-constructed data structure optimized for fast lookup (array for small contexts, hash table for larger contexts). * Implement C++ qualified name lookup in terms of lookup into DeclContext. * Implement C++ unqualified name lookup in terms of qualified+unqualified name lookup (since unqualified lookup is not purely lexical in C++!) * Limit the use of the chains of declarations stored in IdentifierInfo to those names declared lexically. * Eliminate CXXFieldDecl, collapsing its behavior into FieldDecl. (FieldDecl is now a ScopedDecl). * Make RecordDecl into a DeclContext and eliminates its Members/NumMembers fields (since one can just iterate through the DeclContext to get the fields). llvm-svn: 60878
* Disabling this code due to regression on test/CodeGen/bitfield.c. See Eli Friedman2008-12-021-1/+5

| | | | | | | | initializers. llvm-gcc appears to be more aggressive, but incorrect, for constructs like "const int a[] = {1,2,3};"; that said, current optimizers will do the appropriate optimizations when safe. llvm-svn: 60270

* Normalize many BasicBlock names.Daniel Dunbar2008-11-131-3/+3
| | | | | | | | | | - Use dotted notation for blocks related to a particular statement type. - Use .end for landing pads. No functionality change in NDEBUG mode. :) llvm-svn: 59210
* Add CodeGenFunction::EmitBranch.Daniel Dunbar2008-11-111-4/+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 Dunbar2008-08-301-8/+20
| | | | | | | | | | | | | | | | | | | | | | - 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

| | | | | | | | | | | 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
