2010-09-18Fixes IRgen bug in objc++ reference binding of aFariborz Jahanian

2010-09-18Problem with gnu conditional extension with missingFariborz Jahanian
LHS and when conditional expression is an array. Since it will be decayed, saved expression must be saved with decayed expression. This is necessary to preserve semantics of this extension (and prevent an IRGen crash which expects an array to always be decayed). I am sure there will be other cases in c++ (aggregate conditionals for example) when saving of the expression must happen after some transformation on conditional expression has happened. Doug, please review. Fixes // rdar://8446940 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114296 91177308-0d34-0410-b5e6-96231b3b80d8

unless we're on a platform without __cxa_atexit (or use thereof has been disabled).

2010-09-17When we run into an error parsing or type-checking the left-hand sideDouglas Gregor
of a binary expression, continue on and parse the right-hand side of the binary expression anyway, but don't call the semantic actions to type-check. Previously, we would see the error and then, effectively, skip tokens until the end of the statement. The result should be more useful recovery, both in the normal case (we'll actually see errors beyond the first one in a statement), but it also helps code completion do a much better job, because we do "real" code completion on the right-hand side of an invalid binary expression rather than completing with the recovery completion. For example, given x = p->y if there is no variable named "x", we can still complete after the p-> as a member expression. Along the recovery path, we would have completed after the "->" as if we were in an expression context, which is mostly useless. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114225 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-17Currently we're initializing the vtable pointers of a class only afterJohn McCall
the bases are completely initialized. This won't work --- base initializer expressions can rely on the vtables having been set up. Check for uses of 'this' in the initializers and force a vtable initialization if found. This might not be good enough; we might need to extend this to handle the possibility of arbitrary code finding an external reference to this (not yet completely-constructed!) object and accessing through it, in which case we'll probably find ourselves doing a lot more unnecessary stores. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114153 91177308-0d34-0410-b5e6-96231b3b80d8
