* Set unnamed_addr in every type info.Rafael Espindola2011-01-111-4/+2

* Set unnamed_addr for type infos that we are confortable marking as hidden. IRafael Espindola2011-01-111-1/+5
| | | | | | think it is safe to mark all type infos with unnamed_addr, but I am not sure. llvm-svn: 123275

* Better solution: calculate the visibility of functions and variablesJohn McCall2010-10-301-1/+1
| | | | | | | | | | independently of whether they're definitions, then teach IR generation to ignore non-explicit visibility when emitting declarations. Use this to make sure that RTTI, vtables, and VTTs get the right visibility. More of rdar://problem/8613093 llvm-svn: 117781

* Emit standard-library RTTI with external linkage, not weak_odr.John McCall2010-08-041-12/+33
| | | | | | | | | | Apply hidden visibility to most RTTI; libstdc++ does not rely on exact pointer equality for the type info (just the type info names). Apply the same optimization to RTTI that we do to vtables. Fixes PR5962. llvm-svn: 110192

* Eliminate excessive PCH deserialization caused by the search forDouglas Gregor2010-04-081-35/+0
| | | | | | | | | | | | | | | | | | | | | | __cxxabiv1::__fundamental_type_info in every translation unit. Previously, we would perform name lookup for __cxxabiv1::__fundamental_type_info at the end of IRGen for a each translation unit, to determine whether it was present. If so, we we produce type information for all of the fundamental types. However, this name lookup causes PCH deserialization of a significant part of the translation unit, which has a woeful impact on performance. With this change, we now look at each record type after we've generated its vtable to see if it is __cxxabiv1::__fundamental_type_info. If so, we generate type info for all of the fundamental types. This works because __cxxabiv1::__fundamental_type_info should always have a key function (typically the virtual destructor), that will be defined once in the support library. The fundamental type information will end up there. Fixes <rdar://problem/7840011>. llvm-svn: 100772
