14:02:59 stassats do we really need a restart for (intern "x" :a)? as it will imperceptibly slow down INTERN

14:03:29 stassats haven't measured

14:16:37 stassats huh, restart-case conses

14:24:53 stassats solvable

14:31:11 stassats but restarts should be even cheaper

14:31:47 stassats i'm descending into yak shaving

14:32:07 Xach It's for a good cause.

14:33:01 stassats there can be a prefabricated block of restarts, now how to achieve that

14:39:31 stassats i think it can be done relatively painlessly

15:11:17 pfdietz_ It's not clear to me why adding restarts should have any cost for the non-error case.

15:11:33 stassats well, how else would they work?

15:12:13 stassats ok, that's only when you wrap the error directly

15:12:18 pfdietz_ You only create the restart(s) when you are going to signal the error?

15:12:42 stassats but if you wrap around code that might produce an error, it's not zero cost

15:12:56 pfdietz_ Right. So don't do that.

15:26:00 pfdietz_ What's the overhead for handler-case?

17:49:01 karlosz so i think im running into the cheneygc + 64bit thing again with the code component not being recognized by ICF

17:49:22 karlosz is the code folding supposed to work on all platforms?

18:09:53 stassats just disable ICF

18:13:56 karlosz is doing that reprecussionless? then trying to save lisp and die gives me *thread-initial-bindings* is unbound

18:14:02 karlosz im not building with threads, so im stumped

18:14:22 stassats yes, icf is optional

18:14:42 karlosz specifically when trying to coalesce-ctypes

18:14:48 karlosz okay, thats good to know

18:22:19 stassats what says *thread-initial-bindings* is unbound?

18:23:15 karlosz https://paste.gnome.org/pbvenojb8

18:23:22 karlosz i get this backtrace when save-lisp-and-die is run

18:36:56 stassats just remove coalesce-ctypes from deinit

18:40:49 stassats or don't and fix fast-symbol-global-value

18:41:34 karlosz you mean the vop?

18:41:54 stassats yes

18:41:57 karlosz ok

18:43:25 stassats try (define-vop (fast-symbol-global-value fast-symbol-value) (:translate sym-global-val))

18:46:33 karlosz right...
