Alexander Shaposhnikov	b6965f7246	[IR] Add alignment for llvm.threadlocal.address ... This diff sets the alignment attribute for the return value and the argument of llvm.threadlocal.address. (https://github.com/llvm/llvm-project/issues/57438) Test plan: ninja check-all Differential revision: https://reviews.llvm.org/D133741	2022-09-13 23:10:55 +00:00
Chuanqi Xu	bacdf80f42	Use @llvm.threadlocal.address intrinsic to access TLS variable ... This is successor for D125291. This revision would try to use @llvm.threadlocal.address in clang to access TLS variable. The reason why the OpenMP tests contains a lot of change is that they uses utils/update_cc_test_checks.py to update their tests.

Richard Smith	cd4d6d718b	PR48030: Fix COMDAT-related linking problem with C++ thread_local static data members. ... Previously when emitting a C++ guarded initializer, we tried to work out what the enclosing function would be used for and added it to the COMDAT containing the variable if we thought that doing so would be correct. But this was done from a context in which we didn't -- and realistically couldn't -- correctly infer how the enclosing function would be used. Instead, add the initialization function to a COMDAT from the code that creates it, in the case where it makes sense to do so: when we know that the one and only reference to the initialization function is in @llvm.global.ctors and that reference is in the same COMDAT.
