2010-08-20objective-c ivar refactoring patch. IterationsFariborz Jahanian
over ivars for a varienty of puposes is now consolidated into two small routines; DeepCollectObjCIvars and ShallowCollectObjCIvars. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111679 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Fix a major regression with value-initialization of class types withDouglas Gregor
trivial default constructors. We're weren't zero-initializing them, which manifested as <rdar://problem/8320532> (a regression in the GCC test suite) and is likely to have caused significant other breakage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111650 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-19Add some enum goodness as requested by Chris. Now instead of storing theCharles Davis
active C++ ABI as a raw string, we store it as an enum. This should improve performance somewhat. And yes, this time, I started from a clean build directory, and all the tests passed. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111507 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Contextual arity is a feature of mangling expressions; kill offJohn McCall
mangleCallExpression. Also, operator names with unknown arity should be mangled as binary operators; this is actually covered by an oddly- positioned sentence in the ABI document. Fixes PR7891. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111395 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-12Just disable the hidden-visibility optimization for now by hiding it behindJohn McCall
a -cc1 option. The Darwin linker complains about mixed visibility when linking gcc-built objects with clang-built objects, and the optimization isn't really that valuable. Platforms with less ornery linkers can feel free to enable this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110979 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Revise r110163: don't mark weak functions nounwind, because the optimizerJohn McCall

2010-08-11Emit a stop point for delegate constructor call. This gives user a chance to ↵Devang Patel
step into constructor body. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110853 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-11When re-raising an exception after a cleanup, we need to call ↵John McCall
_Unwind_Resume_or_Rethrow instead of _Unwind_Resume. With SJLJ exceptions, this is spelled "_Unwind_SjLj_Resume_or_Rethrow", not "_Unwind_SjLj_Resume", which has significantly different semantics. We should actually never be generating a call to _Unwind_SjLj_Resume directly; even if we were generating true cleanups (which we aren't because of the horrible hack), we should be calling __cxa_end_cleanup() on ARM. I haven't implemented this because there's little point as long as the HH is present. I believe this fixes <rdar://problem/8281377>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110851 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Fix a bug in @finally emission in both the fragile and non-fragile EH schemesJohn McCall
where we weren't accounting for the possibility that a @finally block might have internal cleanups and therefore might write to the cleanup destination slot. Fixes <rdar://problem/8293901>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110760 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-07Allow reference binding of a reference of Objective-C object type toDouglas Gregor
an lvalue of another, compatible Objective-C object type (e.g., a subclass). Introduce a new initialization sequence step kind to describe this binding, along with a new cast kind. Fixes PR7741. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110513 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-07Inline a special case of EmitAggregateCopy into EmitNullInitializationJohn McCall

2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-07Correct -ftrapv to trap on errors, instead of calling theChris Lattner
__overflow_handler entrypoint that David Chisnall made up. Calling __overflow_handler is not part of the contract of -ftrapv provided by GCC, and should never have been checked in in the first place. According to: http://permalink.gmane.org/gmane.comp.compilers.clang.devel/8699 David is using this for some of arbitrary precision integer stuff or something, which is not an appropriate thing to implement on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110490 91177308-0d34-0410-b5e6-96231b3b80d8

these, but it's convenient to mangle them when deferring them (in the 99.99% case where it's not an anonymous union, of course). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110381 91177308-0d34-0410-b5e6-96231b3b80d8

do the right thing with mixed-visibility symbols, so disable the visibility optimization where that's possible, i.e. with template classes (since it's possible that an arbitrary template might be subject to an explicit instantiation elsewhere). 447.dealII actually does this.
