| | | | llvm-svn: 96958
* Implement IsOverriderUsed. This can't be tested yet due to some other bugs :)Anders Carlsson2010-02-231-1/+46

* Stub out IsOverriderUsed.Anders Carlsson2010-02-231-4/+50
| | | | llvm-svn: 96883
* More fixes. Don't try to emit a virtual base vtable if the virtual base in ↵Anders Carlsson2010-02-231-10/+43
| | | | | | question is a primary virtual base of some other base. llvm-svn: 96881
* Always emit vcall offset for the primary base, not only if it's virtual. ↵Anders Carlsson2010-02-231-5/+1
| | | | | | Remove a debug printf, and add the test case that now passes. llvm-svn: 96880
* Simplify the vcall offset calculation and make it give the correct answers ↵Anders Carlsson2010-02-231-26/+17
| | | | | | :) My test case now has the right values but in the wrong order. llvm-svn: 96877
* More work on vcall offsets. We now emit the right number of vcall offsets in ↵Anders Carlsson2010-02-231-5/+1
| | | | | | my local test case, but not the right values. llvm-svn: 96874
* Move BaseOffset out of the FinalOverriders class.Anders Carlsson2010-02-231-45/+44
| | | | llvm-svn: 96853
* Perform two more constructor/destructor code-size optimizations:John McCall2010-02-237-47/+250
| | | | | | | | | | | | | | | | 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. llvm-svn: 96842
* Change the name of the vtable-debugging environment variable toDouglas Gregor2010-02-221-1/+1
| | | | | | CLANG_VTABLE_DEBUG. llvm-svn: 96785
* Don't use NamedDecl::getNameAsCString() when dealing with C++ methods,Douglas Gregor2010-02-221-13/+13
| | | | | | since they may not have normal identifiers for names. Fixes PR6369. llvm-svn: 96784
* Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor2010-02-211-1/+4
| | | | | | | | fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. llvm-svn: 96766
* Add the CK_UnusedFunctionPointer component kind for unused function pointers.Anders Carlsson2010-02-191-3/+34
| | | | llvm-svn: 96695
* More refactoring around constructor/destructor code generation.John McCall2010-02-194-182/+178
| | | | | | | | | | | | Fix some bugs with function-try-blocks and simplify normal try-block code generation. This implementation excludes a deleting destructor's call to operator delete() from the function-try-block, which I believe is correct but which I can't find straightforward support for at a moment's glance. llvm-svn: 96670
* Dump this-adjustments for destructors as well.Anders Carlsson2010-02-191-10/+27
| | | | llvm-svn: 96660
* Re-introduce the ctor/dtor alias optimization, this time hidden behind aJohn McCall2010-02-193-23/+143

* remove unused function & enumerationsBlaine Garst2010-02-192-39/+2
| | | | llvm-svn: 96635
* Revert the ctor/dtor alias optimization for now; the buildbots can detectJohn McCall2010-02-183-142/+26
| | | | | | some failure here that I can't. llvm-svn: 96612
* Make deleting and complete dtor variants defer to other dtor variants byJohn McCall2010-02-182-48/+93
| | | | | | | | calling them as subroutines. This triggers whenever the alias optimization doesn't, i.e. when the dtor has linkonce linkage or there are virtual bases or it's the deleting dtor. llvm-svn: 96605

* Patch to remove arbitrary imporation of 'self' intoFariborz Jahanian2010-02-171-13/+0
| | | | | | | | a block without it being used. This causes over release of objects in certain runtime-senitive apps. (fixes radar 7581175). llvm-svn: 96501

* Use proper lexcial context for newly added ivars.Fariborz Jahanian2010-02-171-0/+2
| | | | llvm-svn: 96484
* Make FinalOverriders handle virtual bases correctly. Unfortunately this ↵Anders Carlsson2010-02-171-3/+33

* Handle primary bases in AddVCallOffsets.Anders Carlsson2010-02-171-2/+9

| | | | llvm-svn: 96455
* Emit complete constructors and destructors as aliases to base constructorsJohn McCall2010-02-173-26/+142
| | | | | | | | and destructors when the two entities are semantically identical, i.e. when the class has no virtual base classes. We only do this for linkage types for which aliases are supported, i.e. internal and external, i.e. not linkonce. llvm-svn: 96451
* Pass through whether a base is virtual or not.Anders Carlsson2010-02-171-17/+26
| | | | llvm-svn: 96449
* implement EmitVAArg. pretty much the same way other targets do.Sanjiv Gupta2010-02-171-1/+21
| | | | llvm-svn: 96446
* Correctly calculate base offsets for 'this' pointer adjustments involving ↵Anders Carlsson2010-02-171-3/+40
| | | | | | virtual bases. This can't be tested yet due to lack of vcall offsets :) llvm-svn: 96441
* IRgen optimization: cache the value of 'this' and 'vtt' instead ofJohn McCall2010-02-164-25/+19
| | | | | | | | repeatedly reloading from an alloca. We still need to create the alloca for debug info purposes (although we currently create it in all cases because of some abstraction boundaries that're hard to break down). llvm-svn: 96403
