- Input:
- 0 - system call number
- 3-8 - arguments, as in C
- Output:
- so - (summary overflow) clear iff successful
- This macro is similar to SYSCALL in asm.h, but not completely.
- There's room for optimization, if we assume this will continue to
- be assembled as one file.
- This macro expansions does not include the return instruction.
- If there's no other work to be done, use something like:
- SYSCALL(foo) ; ret
- If there is other work to do (in fork, maybe?), do it after the
- SYSCALL invocation. */
