John McCall 67da35c832 Extract a common structure for holding information about the definition 
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.

Douglas Gregor 2a34df3264 Fix linkage for RTTI names by re-using the logic for computing the 
linkage of vtables. Before this, we were emitting RTTI names for
template instantiations with strong external linkage rather than with
weak ODR linkage.

Anders Carlsson 2d21394190 If the key function of a record is inline, then the RTTI data should have weak_odr linkage.

Mike Stump bb2f57dd39 Don't set hidden for a non-external symbol as that would make it extenal. 
Refine codegen for visibility and hidden.  WIP.

Anders Carlsson 2b7f444366 Incomplete structs should also have internal linkage.

Anders Carlsson 18e6ee1b20 Correcly handle pointers to member pointer types where the class or the pointee is incomplete.

 2009-12-20 23:37:55 +00:00
Anders Carlsson d008129f34 Rework the way pointer types are handled by the RTTI builder. We now get the right linkage for indirect pointers to incomplete structs.

Daniel Dunbar e017ecc9e2 Remove ';' after method definition. Noticed by clang++, which one would think 
would have a higher respect for its own code. This is getting old, is this
warning really adding value?

Anders Carlsson 3f4336cb1f Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that takes a CXXRecordDecl since we were just creating a QualType from it anyway.

 2009-12-17 05:06:03 +00:00
Anders Carlsson 07863b8b6e Use GetAddrOfRTTI everywhere and remove GenerateRTTI and GenerateRTTIRef. With this change, we can now compile and link TableGen.

Anders Carlsson fd7dfeb779 Improve linkage of RTTI data structures. Introduce CodeGenModule::GetAddrOfRTTI which figures out the right linkage of the RTTI information for the given type and whether it should be defined or not. I will migrate clients over to GetAddrOfRTTI in subsequent commits (with tests).
