| | | | llvm-svn: 92399
* Add a sanity assertion so that we don't silently generate bad code; I'll fileEli Friedman2009-12-271-0/+2
| | | | | | a bug with a testcase hitting this assertion in a moment. llvm-svn: 92175
* Fix obvious mistake.Eli Friedman2009-12-271-1/+1
| | | | llvm-svn: 92172
* Make copy constructor elimination work in more cases; the case in questionEli Friedman2009-12-241-0/+3
| | | | | | here affects clang-on-clang. llvm-svn: 92151

| | | | | | | the constructor. This doesn't handle cases requiring the VTT at the moment, and generates unnecessary stores, but I think it's essentially correct. llvm-svn: 91731
* Fix for PR5830: fix the computation of the offset to a virtual base.Eli Friedman2009-12-181-3/+36

* Switch the initialization required by return statements over to theDouglas Gregor2009-12-181-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | new InitializationSequence. This fixes some bugs (e.g., PR5808), changed some diagnostics, and caused more churn than expected. What's new: - InitializationSequence now has a "C conversion sequence" category and step kind, which falls back to - Changed the diagnostics for returns to always have the result type of the function first and the type of the expression second. CheckSingleAssignmentConstraints to peform checking in C. - Improved ASTs for initialization of return values. The ASTs now capture all of the temporaries we need to create, but intentionally do not bind the tempoary that is actually returned, so that it won't get destroyed twice. - Make sure to perform an (elidable!) copy of the class object that is returned from a class. - Fix copy elision in CodeGen to properly see through the subexpressions that occur with elidable copies. - Give "new" its own entity kind; as with return values and thrown objects, we don't bind the expression so we don't call a destructor for it. Note that, with this patch, I've broken returning move-only types in C++0x. We'll fix it later, when we tackle NRVO. llvm-svn: 91669

| | | | | | | with a non-trivial default constructor, zero-initialize the storage and then call the default constructor. Fixes PR5800. llvm-svn: 91548

* Make copy assignment operator synthesis not explode for classes with complexEli Friedman2009-12-081-2/+10
| | | | | | | | | | | | 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. llvm-svn: 90823
* A bunch more thunk fixes from misc testing.Eli Friedman2009-12-071-20/+26
| | | | | | (Yes, I do intend to commit some tests for this.) llvm-svn: 90818
* Work-in-progess rewrite of thunks: move thunk generation outside of vtableEli Friedman2009-12-061-0/+96
| | | | | | | generation, and make sure we generate thunks when the function is defined rather than when the vtable is defined. llvm-svn: 90722
* CodeGenModule::GenerateVtable now returns a pointer directly to the vtable ↵Anders Carlsson2009-12-051-9/+14

* When generating a virtual destructor, don't try to make a virtual call to ↵Anders Carlsson2009-12-041-10/+18
| | | | | | | | 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. llvm-svn: 90578

| | | | llvm-svn: 90017
* Fix for PR5594: use EmitGlobalDefinition instead of EmitCXXDestructor so thatEli Friedman2009-11-271-3/+3

* Simplify and fix up the handling of implicit constructors, copy assignmentEli Friedman2009-11-261-5/+9
| | | | | | | | operators, and destructors. Avoids generating declarations/definitions of trivial constructors/destructors, and makes sure the trivial copy assignment operator is generated when necessary. llvm-svn: 89943

* Handle references correctly when synthesizing copy constructors.Anders Carlsson2009-11-241-8/+28
| | | | | | | | | | | 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! :) llvm-svn: 89799
* Handle cases where we're constructing an array of objects and the ↵Anders Carlsson2009-11-241-8/+32
