// Performs System Five System Call.
|
||
//
|
||
// Cosmopolitan is designed to delegate all function calls into the
|
||
// Linux, FreeBSD, OpenBSD, and XNU kernels via this function, with
|
||
// few exceptions. This function should generally only be called by
|
||
// generated thunks in the libc/sysv/syscalls/ directory.
|
||
//
|
||
// It's safe to call this function on Windows, where it will always
|
||
// return -1 with errno == ENOSYS. Further note that -1 is the only
|
||
// return value that means error, a common anti-pattern is to check
|
||
// for values less than 0 (which is more problematic on 32-bit).
|
||
//
|
||
// It is important to consider that system calls are one order of a
|
||
// magnitude more expensive than normal function calls. For example
|
||
// getpid() on Linux usually takes 500ns, and cached i/o calls will
|
||
// take 1µs or more. So we don't need to inline them like Chromium.
|
||
//
|
||
// Another thing to consider is that BSDs only loosely follow the
|
||
// System Five ABI for the SYSCALL instruction. For example Linux
|
||
// always follows the six argument limit but the FreeBSD sendfile
|
||
// system call accepts a seventh argument that is passed on stack
|
||
// and OpenBSD modifies functions like mmap so that the sixth arg
|
||
// is passed on the stack. There's also the carry flag convention
|
||
// that XNU, FreeBSD, and OpenBSD inherited from 386BSD aka Jolix
|
||
//
|
||
// @param %rax function ordinal supplied by jump slot
|
||
// @param %rdi,%rsi,%rdx,%rcx,%r8,%r9 and rest on stack
|
||
// @return %rax:%rdx is result, or -1 w/ errno on error
|
||
// @clob %rcx,%r10,%r11
|
||
// @see syscalls.sh
