[PATCH] D145131: [Arm][AArch64] Setting IsX18ReservedByDefault() to true for Unknown OSes

[Benoit Jacob via Phabricator via llvm-commits]

Benoit added a comment.

I'm not legitimate as a reviewer here, but as a user I'll voice a big +1 for this. It is common to be using target triples with unknown OS, and without this patch, doing so results in very hard to debug issues in code that uses x18.
