2023-12-22coroutine/arm64: Skip saving/restoring x30 twice and use `autiasp`Yuta Saito
We don't need to save/restore x30 twice, and we can just use `ret`, which uses x30 as return address register instead of explicit `ret <reg>` instruction. This also allows us to use `autiasp` instead of `autia1716` and we can skip setting SP/LR to x16/x17. Also the size of register save area is shrunk by 16 bytes due to the removal of extra x30 save/restore.

2018-11-24Change Makefile rule for assembly to use .S rather than .ssamuel
It is more conventional to use compiler to pre-process and assemble the `.S` file rather than forcing Makefile to use `.s`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65952 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
