This means that the GlobalISel IRTranslator's implementation for Intrinsic::stackprotector is broken for platforms that implement getIRStackGuard() like we do, and this causes a segfault later when the incomplete LOAD_STACK_GUARD pseudo is lowered in the back end. Since GlobalISel is disabled on aarch64 most of the time anyway, add a bit that disables it for OpenBSD/aarch64 all the time. Fixes a crash when building on aarch64 without retguard, with a stack protector and without optimizations, which manifests when building cross-tools. ok patrick@ deraadt@ Import LLVM 8.0.0 release including clang, lld and lldb. 2019-06-23T21:36:31Z patrick patrick@openbsd.org 2019-06-23T21:36:31Z urn:sha1:23f101f37937a1bd4a29726cab2f76e0fb038b35 Import LLVM 7.0.1 release including clang, lld and lldb. 2019-01-27T16:42:12Z patrick patrick@openbsd.org 2019-01-27T16:42:12Z urn:sha1:b773203fb58f3ef282fb69c832d8710cab5bc82d Import LLVM 6.0.1 release including clang, lld and lldb. 2018-04-06T14:26:03Z patrick patrick@openbsd.org 2018-04-06T14:26:03Z urn:sha1:bdabc2f19ffb9e20600dad6e8a300842a7bda50e "where is the kaboom?" deraadt@ Import LLVM 5.0.0 release including clang, lld and lldb. 2017-10-04T20:27:34Z patrick patrick@openbsd.org 2017-10-04T20:27:34Z urn:sha1:31eb748944903b7f4f38afda9851951ca9dfc1ae Import LLVM 4.0.0 rc1 including clang and lld to help the current 2017-01-24T08:32:59Z patrick patrick@openbsd.org 2017-01-24T08:32:59Z urn:sha1:53d771aafdbe5b919f264f53cba3788e2c4cffd2 development effort on OpenBSD/arm64.
