Make _Thread_local work across platforms We now rewrite the binary image at runtime on Windows and XNU to change mov %fs:0,%reg instructions to use %gs instead. There's also simpler threading API introduced by this change and it's called _spawn() and _join(), which has replaced most clone() usage. 2022-07-10 11:01:17 +00:00			`#ifndef COSMOPOLITAN_LIBC_THREAD_SPAWN_H_`
