// Syscall3 performs a 3 argument syscall.  Syscall3 differs from
// syscall.[Raw]Syscall() insofar as it is simultaneously executed on
// every thread of the combined Go and CGo runtimes. It works
// differently depending on whether CGO_ENABLED is 1 or 0 at compile
// time.
//
// If CGO_ENABLED=1 it uses the libpsx function C.psx_syscall3().
//
// If CGO_ENABLED=0 it redirects to the go1.16+
// syscall.AllThreadsSyscall() function.

// combined Go and CGo runtimes. Other than the number of syscall
// arguments, its behavior is identical to that of Syscall3() - see
