Issue #18439 has been updated by YO4 (Yoshinao Muramatsu). The Windows version of ruby limits Integer to 30 bits even in x64 environments. I am afraid that to support this in yjit would add complexity, which would harm the evolution of yjit. Would 30bit Integer support actually have a negative impact? Nevertheless, regardless of yjit support, I would like to see the Windows version of Integer's limitation removed. ---------------------------------------- Feature #18439: YJIT: Support Microsoft x86 calling convention https://bugs.ruby-lang.org/issues/18439#change-111120 * Author: usa (Usaku NAKAMURA) * Status: Assigned * Assignee: yjit ---------------------------------------- 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/
