After some discussion, it was decided to use the Itanium ABI for thread_local on Darwin OS X platforms. This involved a couple of changes. First, we use "_tlv_atexit" instead of "__cxa_thread_atexit". Secondly, the global variables are marked with 'internal' linkage, because we want all access to be calls to the Itanium-specific entry point, which has normal linkage. <rdar://problem/13733006> llvm-svn: 180941
