I'm crunching out some complex 'make' rules , and am having a brain
fart as to what sorts of rules are safe to use with '-j'.
As a matter of example, I'm looking at /usr/share/mk/sys.mk under
4.5-RELEASE:
# XXX not -j safe
.y.out:
${YACC} ${YFLAGS} ${.IMPSRC}
${CC} ${CFLAGS} ${LDFLAGS} y.tab.c ${LDLIBS} -ly -o ${.TARGET}
rm -f y.tab.c
.l.out:
${LEX} -t ${LFLAGS} ${.IMPSRC} > ${.PREFIX}.tmp.c
${CC} ${CFLAGS} ${LDFLAGS} ${.PREFIX}.tmp.c ${LDLIBS} -ll -o ${.TARGET}
rm -f ${.PREFIX}.tmp.c
Why is the .y.out target annotated as 'not -j safe', but the next
target is?
