* Improve vcall offset handling.Anders Carlsson2010-02-251-12/+26
| | | | llvm-svn: 97174
* Fux a bug where we were trying to add overriders for non-virtual bases of ↵Anders Carlsson2010-02-251-3/+3
| | | | | | virtual bases more than once. llvm-svn: 97173
* Targets (like pic16) may have mangled the name of global variables, Sanjiv Gupta2010-02-251-1/+1
| | | | | | so get the name from Var rather than the original decl. llvm-svn: 97114
* Remove dead code.Anders Carlsson2010-02-251-176/+0
| | | | llvm-svn: 97109
* Move the vcall and vbase offset layout code out into its own class.Anders Carlsson2010-02-251-8/+224
| | | | llvm-svn: 97107
* Get rid of 'this' adjustments from the FinalOverriders class since they can ↵Anders Carlsson2010-02-241-34/+0
| | | | | | be different for the same overrider in different parts of the vtable. llvm-svn: 97068
* Improve this adjustment pointer calculation.Anders Carlsson2010-02-241-5/+16
| | | | llvm-svn: 97067
* Make ComputeThisAdjustmentBaseOffset public for now.Anders Carlsson2010-02-241-7/+8
| | | | llvm-svn: 97066
* Fix an iterator-invalidation bug that was causing selfhost errorsJohn McCall2010-02-241-10/+6
| | | | | | | on non-darwin platforms. Fixes PR6411. Test case doesn't reduce, unfortunately. llvm-svn: 97055
* Generate correct vcall offsets when we have a primary virtual base that is ↵Anders Carlsson2010-02-241-7/+29
| | | | | | not a primary base in the complete class hierarchy. llvm-svn: 97039
* Canonicalize parameter and return types before computing ABI info. EliminatesJohn McCall2010-02-244-71/+78
| | | | | | | | | | | a common source of oddities and, in theory, removes some redundant ABI computations. Also fixes a miscompile I introduced yesterday by refactoring some code and causing a slightly different code path to be taken that didn't perform *parameter* type canonicalization, just normal type canonicalization; this in turn caused a bit of ABI code to misfire because it was looking for 'double' or 'float' but received 'const float'. llvm-svn: 97030
* Emit debug info for VectorType.Devang Patel2010-02-232-2/+26
| | | | llvm-svn: 96999
* Add support for the weakref attribute. We still produce "alias weak" as ↵Rafael Espindola2010-02-231-0/+1
| | | | | | llvm-gcc does, but are more strict on what uses of weakref we accept. llvm-svn: 96992
* Unconditionally support block introspection data in a new field at the endBlaine Garst2010-02-233-55/+46
| | | | | | | | | | | | | | | of the block descriptor field. This field is the ObjC style @encode signature of the implementation function, and was to this point conditionally provided in the block literal data structure. That provisional support is removed. Additionally, eliminate unused enumerations for the block literal flags field. The first shipping ABI unconditionally set (1<<29) but this bit is unused by the runtime, so the second ABI will unconditionally have (1<<30) set so that the runtime can in fact distinguish whether the additional data is present or not. llvm-svn: 96989
* Make previous fix handle a few more edge cases.Eli Friedman2010-02-231-3/+3
| | | | llvm-svn: 96962
* PR6400: Handle an extreme edge case in mangling correctly.Eli Friedman2010-02-231-0/+3

* PR6386: Fix a recent regression in IRGen of cast-to-union constructs.Eli Friedman2010-02-231-1/+1
| | | | llvm-svn: 96958
* Implement IsOverriderUsed. This can't be tested yet due to some other bugs :)Anders Carlsson2010-02-231-1/+46
| | | | llvm-svn: 96897
* 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

* 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
