[PATCH] D91719: [RISCV] Add support for using -msave-restore with tailcalls

[Edward Jones via Phabricator via llvm-commits]

edward-jones updated this revision to Diff 354822.
edward-jones added a comment.

I've rebased and added an option so that the tailcall version of save/restore is only used if `-mllvm -riscv-save-restore-tailcall` is provided.
