2010-02-24Get rid of 'this' adjustments from the FinalOverriders class since they can ↵Anders Carlsson
be different for the same overrider in different parts of the vtable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97068 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24Fix an iterator-invalidation bug that was causing selfhost errorsJohn McCall
on non-darwin platforms. Fixes PR6411. Test case doesn't reduce, unfortunately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97055 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Generate correct vcall offsets when we have a primary virtual base that is ↵Anders Carlsson
not a primary base in the complete class hierarchy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97039 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Canonicalize parameter and return types before computing ABI info. EliminatesJohn McCall
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'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97030 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Add support for the weakref attribute. We still produce "alias weak" as ↵Rafael Espindola
llvm-gcc does, but are more strict on what uses of weakref we accept. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96992 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Unconditionally support block introspection data in a new field at the endBlaine Garst
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96989 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96897 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23More fixes. Don't try to emit a virtual base vtable if the virtual base in ↵Anders Carlsson
question is a primary virtual base of some other base. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96881 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Always emit vcall offset for the primary base, not only if it's virtual. ↵Anders Carlsson
Remove a debug printf, and add the test case that now passes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96880 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Simplify the vcall offset calculation and make it give the correct answers ↵Anders Carlsson
:) My test case now has the right values but in the wrong order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96877 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23More work on vcall offsets. We now emit the right number of vcall offsets in ↵Anders Carlsson
my local test case, but not the right values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96874 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Perform two more constructor/destructor code-size optimizations:John McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96842 91177308-0d34-0410-b5e6-96231b3b80d8

CLANG_VTABLE_DEBUG. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96785 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-22Don't use NamedDecl::getNameAsCString() when dealing with C++ methods,Douglas Gregor
since they may not have normal identifiers for names. Fixes PR6369. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96784 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor
fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96766 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-19More refactoring around constructor/destructor code generation.John McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96670 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-19Re-introduce the ctor/dtor alias optimization, this time hidden behind aJohn McCall
command-line option which defaults off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96649 91177308-0d34-0410-b5e6-96231b3b80d8

some failure here that I can't. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96612 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-18Make deleting and complete dtor variants defer to other dtor variants byJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96605 91177308-0d34-0410-b5e6-96231b3b80d8
