[PATCH] D66278: [RISCV] Enable tail call opt for variadic function

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

Please may you explain a bit further why calls using varargs (when not passed by the stack) are allowed to be tail-call-optimised?

I feel the justification would be good documentation to go with the patch, and will help out me and other reviewers.
