@llvm/pr-subscribers-llvm-adt Author: no92 (no92) ChangesThis PR is part of a series to upstream managarm support, as laid out in the RFC. This PR is a follow-up to #87845. The intention here is to add the managarm target to the LLVM support lib, in preparation for a follow-up that would add the missing clang driver bits.
