1# Implement symbols common to libc and libsys.
2#
3# When dynamically linked, the libc symbols are filtered by the actual
4# implementations in libsys.  When statically linked, both libc and
5# libsys contain full implementations to preserve the API of libc.a.
6#
7# The following variable are programmer-defined:
8#
9# MDASM		Override the default syscall implementation in MIASM
10#		(from syscall.mk below).  Each entry is a source file
11#		name (e.g., vfork.S).
12#		Generally defined in <arch>/Makefile.sys.
13# NOASM		Don't generate system call stubs.  Each entry is an
14#		object file name (e.g., yeild.o).  Don't add more of these.
15# PSEUDO	Generate _<sys> and __sys_<sys> symbols, but not <sys>.
16#		Each entry is a bare syscall name (e.g., "clock_gettime").
17# INTERPOSED	Like PSEUDO, but <sys>.c is added to SRCS.
18#		Used for syscalls intercepted by the threading library.
19#
