Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

Turn access control on by default in -cc1. Remove -faccess-control from -cc1; add -fno-access-control. Make the driver pass -fno-access-control by default. Update a bunch of tests to be correct under access control. llvm-svn: 100880

Mark VTables and RTTI data linkonce_odr instead of weak_odr, with the exception of explicit template instantiations, which have to be weak_odr. This fixes PR6996. llvm-svn: 124089

When marking virtual functions as used for a class' vtable, mark all functions which will appear in the vtable as used, not just those ones which were declared within the class itself. Fixes an issue reported as comment#3 in PR12763 -- we sometimes assert in codegen if we try to emit a reference to a function declaration which we've not marked as referenced. This also matches gcc's observed behavior. llvm-svn: 159895
