From: "maximecb (Maxime Chevalier-Boisvert)" Date: 2022-01-10T23:29:13+00:00 Subject: [ruby-core:107031] [Ruby master Feature#18439] Support YJIT for VC++ Issue #18439 has been updated by maximecb (Maxime Chevalier-Boisvert). Supporting Windows is in the plans, but as my colleagues have said it's fairly tricky as it could add a fair bit of complexity in several places. We're hoping to potentially migrate the YJIT codebase to Rust, which would give us more tools to manage the complexity, and could facilitate a project like this. ---------------------------------------- Feature #18439: Support YJIT for VC++ https://bugs.ruby-lang.org/issues/18439#change-95862 * Author: usa (Usaku NAKAMURA) * Status: Open * Priority: Normal * Assignee: maximecb (Maxime Chevalier-Boisvert) ---------------------------------------- I heard that supporting YJIT for VC++ needs mmap from k0kubun-san, so I implemented tiny mmap emulation on Windows and committed it to master. And, I found we need more changes to actually enabled YJIT for VC++, at least: - YJIT requires `OPT_DIRECT_THREADED_CODE` or `OPT_CALL_THREADED_CODE` in `rb_yjit_compile_iseq()`. Really? - Maybe ABI deffers between VC++ and YJIT's expectation. Can I get support to fix above? -- https://bugs.ruby-lang.org/ Unsubscribe:
