Huh. Disappointing. When I was poking at CANNOT_DUMP startup time about a year ago, I seem to recall that these helped, but I don’t remember how much. A couple other things though:
* Since you (presumably) didn’t configure with CANNOT_DUMP, temacs may still be making “pure” copies of objects. But I just tried rebuilding with CANNOT_DUMP, and temacs aborted in bidi_initialize; I’m guessing it wants to use something initialized by Lisp code that hasn’t run yet.
* If you’re on a Mac, loading elisp is extra slow, thanks to getc() calling mutex functions that are very slow (at least compared to the glibc versions); I tried out a workaround using getc_unlocked, which seemed to help a lot.
