URL: https://github.com/llvm/llvm-project/commit/380fee34d2794361f9e222fe3c8c065be3b9fff8 DIFF: https://github.com/llvm/llvm-project/commit/380fee34d2794361f9e222fe3c8c065be3b9fff8.diff LOG: [libunwind] Provide a way to set '_LIBUNWIND_IS_BAREMETAL' through cmake. Libunwind uses _LIBUNWIND_IS_BAREMETAL in a lot of places but there is no cmake variable to set it. This patch adds such a variable. It is quite like what LIBCXXABI_BAREMETAL does in libcxxabi.
