Subject: Regenerate semantic grammars if the generating code changes
X-Git-Tag: emacs-28.0.90~3014
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9cb3db0bade2ea43bad9cadc7864887c09bc7cd0;p=emacs.git

Regenerate semantic grammars if the generating code changes

* admin/grammars/Makefile.in (emacs): Set load-prefer-newer.
(grammar_bovine, grammar_wisent): New variables.
(${bovinedir}/%-by.el, ${bovinedir}/scm-by.el)
(${cedetdir}/semantic/%-wy.el, ${wisentdir}/%-wy.el)
(${wisentdir}/javat-wy.el, ${cedetdir}/srecode/srt-wy.el):
Depend on the source file for the generating function.
* lisp/cedet/semantic/bovine/grammar.el (bovine--make-parser-1):
* lisp/cedet/semantic/wisent/grammar.el (wisent--make-parser-1):
Force generation of the output file.  The previous "is the output
newer than the input" failed to account for changes in the
generation code itself.  Force so we can let make figure it out.
