[PATCH] D65019: [ARM] push LR before __gnu_mcount_nc on ARM

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I don't like introducing magic calling convention rules for a non-intrinsic function with a specific name; we should model this more explicitly somehow.  Probably the simplest thing to do would be to introduce an ARM intrinsic, lower it to a pseudo-instruction, and expand it late (in ExpandPostRAPseudos or something like that).
