Move all variables at file-scope or function-static-scope into a hosting structure (lld::CommonLinkerContext) that lives at lldMain()-scope. Drivers will inherit from this structure and add their own global state, in the same way as for the existing COFFLinkerContext. See discussion in https://lists.llvm.org/pipermail/llvm-dev/2021-June/151184.html The previous landf860fe3622caused issues in https://lab.llvm.org/buildbot/#/builders/123/builds/8383, fixed by22ee510dac.
