| //! Inline asm for making system calls. |
| //! |
| //! Compilers should really have intrinsics for making system calls. They're |
| //! much like regular calls, with custom calling conventions, and calling |
| //! conventions are otherwise the compiler's job. But for now, use inline asm. |
| //! |
| //! The calling conventions for Linux syscalls are [documented here]. |
