2011-01-29Remove IsDefinition from CodeGenModule::setTypeVisibility; it is always true.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124529 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-24When building a type info struct for EH, we always want it to have ↵Anders Carlsson
linkonce_odr linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124096 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-24Change CodeGenModule::getVTableLinkage to be a non-static member function.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124095 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-24Mark VTables and RTTI data linkonce_odr instead of weak_odr, with the ↵Anders Carlsson
exception of explicit template instantiations, which have to be weak_odr. This fixes PR6996. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124089 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-11Set unnamed_addr in every type info.Rafael Espindola

2011-01-11Set unnamed_addr for type infos that we are confortable marking as hidden. IRafael Espindola
think it is safe to mark all type infos with unnamed_addr, but I am not sure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123275 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-25The -fshort-wchar option causes wchar_t to become unsigned, in addition to beingChris Lattner
16-bits in size. Implement this by splitting WChar into two enums, like we have for char. This fixes a miscompmilation of XULRunner, PR8856. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122558 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-17Give hidden visibility to RTTI for derived types. This is kindof a hackyJohn McCall
way to do this, but it fixes rdar://problem/8778973 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122033 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-31Rename getBaseClassOffset to getBaseClassOffsetInBits and introduce a ↵Anders Carlsson
getBaseClassOffset which returns the offset in CharUnits. Do the same thing for getVBaseClassOffset. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117881 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-30Better solution: calculate the visibility of functions and variablesJohn McCall
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 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117781 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22Substantially revise how clang computes the visibility of a declaration toJohn McCall
more closely parallel the computation of linkage. This gets us to a state much closer to what gcc emits, modulo bugs, which will undoubtedly arise in abundance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117147 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

2010-08-11Work in progress for PR7864. Someone more familiar with ObjC++ needs to fillEli Friedman

2010-08-04Emit standard-library RTTI with external linkage, not weak_odr.John McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110192 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-02When building RTTI descriptors for pointer types, we need to get the ↵Anders Carlsson
unqualified array type and the qualifiers from it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105326 91177308-0d34-0410-b5e6-96231b3b80d8

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

2010-02-04Extract 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
