Bill Wendling	95cae88bcf	Use the Itanium ABI for thread_local on Darwin. ... 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	2013-05-02 19:18:03 +00:00
Richard Smith	e6c878c0c6	Revert r180739 and r180748: they broke C++11 thread_local on non-Darwin systems and did not do the right thing on Darwin. ... Original commit message: Emit the TLS intialization functions into a list. Add the TLS initialization functions to a list of initialization functions. The back-end takes this list and places the function pointers into the correct section. This way they're called before `main().' <rdar://problem/13733006> llvm-svn: 180809	2013-04-30 21:34:13 +00:00
