> Hi @lhames, we know MCJIT/RuntimeDyld are going to be removed, but this change is necessary to get LoongArch support in lldb (https://github.com/llvm/llvm-project/pull/114742).

We're actually working to get LLDB moved over to ORC, but that will take a little while. This seems like a reasonable step in the mean time. Thanks for working on this @wangleiat !
