[xemacs-hg @ 2003-02-14 12:05:06 by ben] speedups to build process autoload.el: Factor out common code in generate-{c-,}file-autoloads-1 into new function generate-autoload-ish-1. \(I was originally going to use this for custom as well but ended up thinking better of it.) cus-dep.el: Cache the old computed values in custom-load.el and reuse them as necessary, to speed up running cus-dep (which would take 25-30 seconds to do all files in lisp/*, lisp/*/* on my Pentium III 700). Use `message' not `princ' to get correct newline behavior. Output messages showing each file we do actually process. update-elc-2.el: Rewrite algorithm to be much faster -- cache calls to directory-files and don't make needless calls to file-exists-p, file-directory-p because they're way way slow. Autoload early and only when update-elc has told us to. update-elc.el: If no files need byte compilation, signal to update-elc-2 to do any necessary autoload updating (using the file REBUILD_AUTOLOADS) rather than doing it ourselves, which would be way slow. Ignore updates to custom-load.el and auto-autoloads.el when checking to see whether autoloads need updating. Optimize out many unnecessary calls to file-exists-p to speed it up somewhat. (#### The remaining time is 50% or more in locate-file; this is presumably because, even though it has a cache, it's still statting each file to determine it's actually there. By calling directory-files ourselves, building a tree, and then looking in that tree, we could drastically shorten the time needed to do the locate operation.)
