ruby.git/wasm/missing.c, branch v4.0.3 The Ruby Programming Language [wasm] Stop using mprotect(PROT_NONE) on WASI 2025-02-19T02:46:12+00:00 Yuta Saito kateinoigakukun@gmail.com 2025-02-18T16:06:36+00:00 eac35edfd1101e8f7c34dbdd7b595fdac8f0ad4c we had been using a stub weak definition of `mprotect` in wasm/missing.c so far, but wasi-sdk 23 added mprotect emulation to wasi-libc[^1], so the emulation is now linked instead. However, the emulation doesn't support PROT_NONE and fails with ENOSYS, so we need to avoid calling mprotect completely on WASI.
