- sillycross 3y agoLook at the CPS-version of the add.
- celeritascelery 3y agoI saw that. I think I understand a little better. The CPS is to remove the calls between bytecodes, but wouldn’t do anything about lua function calls.
- sillycross 3y agoThat's correct. Lua function calls are not that easy to remove, as function is first-class value in Lua so can be redefined at any time. To remove a function call, you need speculative compilation and OSR-exit, which is outside the job of the baseline JIT.
