From f3b4f99007cdcb3306484c9a39d31addc20aaa69 Mon Sep 17 00:00:00 2001 From: Thomas Lively Date: Thu, 28 Feb 2019 18:39:08 +0000 Subject: [WebAssembly] Remove uses of ThreadModel Summary: In the clang UI, replaces -mthread-model posix with -matomics as the source of truth on threading. In the backend, replaces -thread-model=posix with the atomics target feature, which is now collected on the WebAssemblyTargetMachine along with all other used features. These collected features will also be used to emit the target features section in the future. The default configuration for the backend is thread-model=posix and no atomics, which was previously an invalid configuration. This change makes the default valid because the thread model is ignored. A side effect of this change is that objects are never emitted with passive segments. It will instead be up to the linker to decide whether sections should be active or passive based on whether atomics are used in the final link.
