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