[Emacs-diffs] master 440bafe: Write updated loaddefs to a temporary file and rename into place. |

branch: master
commit 440bafef7cce6044d4f9d6ca3c3e0856ee9732b7
Author: Ken Raeburn <address@hidden>
Commit: Ken Raeburn <address@hidden>
Write updated loaddefs to a temporary file and rename into place.
In a parallel build, byte compilation can be running at the same times
as loaddefs.el is being regenerated. However, in a CANNOT_DUMP build,
loaddefs.el is read at startup and must always be in a usable state.
* lisp/Makefile.in ($(lisp)/loaddefs.el): Write generated output to
loaddefs.el.new and then rename it to loaddefs.el.
