[PATCH] D75428: [MC][ARM] add implicit immediate form for ldrsbt/ldrht/ldrsht

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Generally, we prefer to use an alias unless there's some reason we need logic written in C++.  For example, some "instructions" don't translate to a single instruction.  And some instructions have complex logic for which encoding to use.

In this case, ARMAsmPseudo seems like overkill; an InstAlias should be sufficient.
