2010-04-08Eliminate excessive PCH deserialization caused by the search forDouglas Gregor
__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>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100772 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-31Drastically simplify the computation of linkage for typeinfo by usingDouglas Gregor
the existing (and already well-tested) linkage computation for types, with minor tweaks for dynamic classes and (pointers to) incomplete types. Fixes PR6597. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99968 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27When given the magic class __cxxabiv1::__fundamental_type_info, produceRafael Espindola
the typeinfo for the fundamental types. Fixes PR6685. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99701 91177308-0d34-0410-b5e6-96231b3b80d8

what it actually does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98248 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-04Extract a common structure for holding information about the definitionJohn McCall
of a C++ record. Exposed a lot of problems where various routines were silently doing The Wrong Thing (or The Acceptable Thing in The Wrong Order) when presented with a non-definition. Also cuts down on memory usage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95330 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06Fix linkage for RTTI names by re-using the logic for computing theDouglas Gregor
linkage of vtables. Before this, we were emitting RTTI names for template instantiations with strong external linkage rather than with weak ODR linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92857 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-11Improve linkage of RTTI data structures. Introduce ↵Anders Carlsson
