Ulrich Weigand bebd59c74b [SystemZ] Support all TLS access models - CodeGen part ... The current SystemZ back-end only supports the local-exec TLS access model. This patch adds all required CodeGen support for the other TLS models, which means in particular: - Expand initial-exec TLS accesses by loading TLS offsets from the GOT using @indntpoff relocations. - Expand general-dynamic and local-dynamic accesses by generating the appropriate calls to __tls_get_offset. Note that this routine has a non-standard ABI and requires loading the GOT pointer into %r12, so the patch also adds support for the GLOBAL_OFFSET_TABLE ISD node. - Add a new platform-specific optimization pass to remove redundant __tls_get_offset calls in the local-dynamic model (modeled after the corresponding X86 pass). - Add test cases verifying all access models and optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229654 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-18 09:13:27 +00:00
