[Eli Friedman via Phabricator via llvm-commits]

> In one diff you disable inlining for SME functions. I am afraid that there are more incompatible transformations on functions, i.e., function merging, hot-cold splitting, outlining, ...

Having different functions using different instruction set extensions isn't that unusual.  We support that sort of thing on many different targets, including x86.  (I haven't looked at the diffs to see if it's using the usual target hooks for this.)
