New Revision: 294878
URL: https://svnweb.freebsd.org/changeset/base/294878
Log:
Revert yacc dependency back to pre-r241298.
Several attempts to fix this logic was done after r241298, which were
all reverted, yet this change was not.
The .h file does not depend on the .c file, so do not impose such a
dependency on it. They are generated by the same command but do not
depend on each other. Restore the .ORDER which should handle parallel build
issues. This fixes an actual bug where the .h file is not recreated
when missing [1]. For example:
cd lib/libc
make cleanobj
make nsparser.h
rm nsparser.h
make nsparser.h # will not rebuild nsparser.h
I have been trying to track down a build problem where nsparser.h is
missing when nslexer.o is built. It is possible this is related.
