[PATCH] D11476: Marked call instruction in thunk function with musttail attribute when applicable

[Reid Kleckner]

rnk added a comment.

Musttail is currently x86 only, unfortunately. I started making it work for AArch64, but it was pretty hard and I gave up to work on other things.

That aside, musttail is also somewhat optimization hostile. It interacts with the inliner in surprising ways.

All in all, I'd rather not do this.
