2009-12-08Fix some direct checks of expressions which might be surrounded by parentheses.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90825 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-08Make copy assignment operator synthesis not explode for classes with complexEli Friedman
or non-record aggregate members. It might be worth spending some time to optimize this code (and the parallel code for copy constructors) to memcpy in larger chunks, rather than copying one member at a time. Not sure exactly how beneficial that would be, but it seems like could help for large classes with, for example, a vtable pointer forcing the generation of a copy constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90823 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-07A bunch more thunk fixes from misc testing.Eli Friedman
(Yes, I do intend to commit some tests for this.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90818 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-06Work-in-progess rewrite of thunks: move thunk generation outside of vtableEli Friedman
generation, and make sure we generate thunks when the function is defined rather than when the vtable is defined. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90722 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-05CodeGenModule::GenerateVtable now returns a pointer directly to the vtable ↵Anders Carlsson
and not to the address point. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90676 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-04When generating a virtual destructor, don't try to make a virtual call to ↵Anders Carlsson
the base class destructor because then we'll just re-enter the same destructor! This was done to fix PR5619, so I went ahead and passed a dummy VTT pointer for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90578 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-26Simplify and fix up the handling of implicit constructors, copy assignmentEli Friedman
operators, and destructors. Avoids generating declarations/definitions of trivial constructors/destructors, and makes sure the trivial copy assignment operator is generated when necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89943 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-24Handle references correctly when synthesizing copy constructors.Anders Carlsson
With this change, the clang-on-clang test result is now Expected Passes : 224 Unexpected Failures: 37 Which means that we can compile over 80% of clang with clang! :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89799 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-14PR5483: Generate missing form of destructor when it is virtual. (SomeoneEli Friedman
more familiar with this stuff should double-check that there isn't some more general rule; this is purely from inspecting g++ output.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88755 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-13Instead of storing CXXMethodDecls in the vtable builder, store GlobalDecls ↵Anders Carlsson
so we can represent both the complete and deleting destructors. Also, when encountering a destructor decl, emit entries for both the complete and deleting destructors. Mike, please review. With this change, FileCheck builds and runs the clang test suite without failures! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88663 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-13Add a special BuildVirtualCall that's going to be used for building calls to ↵Anders Carlsson
destructors. This is needed because when compiling: struct A { virtual ~A(); }; void f(A* a) { delete a; } A's deleting destructor should be called. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@87083 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-13Fix two bugs with temporaries:Anders Carlsson
1. For A f() { return A(); } we were incorrectly calling the A destructor on the returned object. 2. For void f(A); void g() { A a; f(a); } we were incorrectly not calling the copy constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@87082 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-09Unify the codepaths used to verify base and member initializers for explicitlyEli Friedman
and implicitly defined constructors. This has a number of benefits: 1. Less code. 2. Explicit and implicit constructors get the same diagnostics. 3. The AST explicitly contains constructor calls from implicit default constructors. This allows handing some cases that previously weren't handled correctly in IRGen without any additional code. Specifically, implicit default constructors containing calls to constructors with default arguments are now handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86500 91177308-0d34-0410-b5e6-96231b3b80d8
