Subject: syscall overhaul part two - unify public and internal syscall interface
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=685e40bb09f5f24a2af54ea09c97328808f76990;hp=685e40bb09f5f24a2af54ea09c97328808f76990;p=musl

syscall overhaul part two - unify public and internal syscall interface

with this patch, the syscallN() functions are no longer needed; a
variadic syscall() macro allows syscalls with anywhere from 0 to 6
arguments to be made with a single macro name. also, manually casting
each non-integer argument with (long) is no longer necessary; the
casts are hidden in the macros.

some source files which depended on being able to define the old macro
SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall()
instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL
have also been changed.

x86_64 has not been tested, and may need a follow-up commit to fix any
minor bugs/oversights.
