 160 ## Comments on loaddefs generation:
 161
 162 # loaddefs depends on gen-lisp for two reasons:
 163 # 1) In ../src, the emacs target depends on loaddefs but not on eg leim-list.
 164 # So having leim as a dependency of loaddefs (via gen-lisp) ensures leim-list
 165 # gets created before the final emacs is dumped.  Having leim
 166 # dependencies in ../src as well would create a parallel race condition.
 167 #
 168 # 2) Files that are marked no-update-autoloads still get recorded in loaddefs.
 169 # So those files should be generated before we make autoloads, if we
 170 # don't want a successive make autoloads to change the output file.
 171 # Said changes are trivial (only comments in the "files without autoloads"
 172 # section), but still can be annoying.  Of course, if generated lisp files
 173 # do contain autoloads, it is essential they be built before make autoloads.
 174 # (Also, if a generated file is not written atomically, it is possible that
 175 # in a parallel build, make autoloads could read a partial version of it.)
 176 #
 177 # We'd really like to add "make -C ../admin/unidata all" to gen-lisp
 178 # because of 2) above, but it causes a race condition in parallel
 179 # builds because ../src also runs that rule.  Given the limitations of
 180 # recursive make, the only way to fix that would be to remove unidata
 181 # from ../src rules, but that doesn't seem possible due to the various
 182 # non-trivial dependencies.
 183
 184 # We make $(lisp)/loaddefs.el a dependency of .PHONY to cause Make to
 185 # ignore its time stamp.  That's because the real dependencies of
 186 # loaddefs.el aren't known to Make, they are implemented in
 187 # batch-update-autoloads, which only updates the autoloads whose
 188 # sources have changed.
