Thanks for spotting the issue and providing the fix. I'm not sure why `loope` would make `llvm-mc` emit relocation and `.byte main-.` would not. I suggest not to rely on the `loope` behavior and issue `.byte main-.` in a different section, e.g. `.rodata`. I.e. if you insert `.rodata` before `.globl P`, it will force `llvm-mc` to always emit a relocation.
