I just updated the noverlay branch to the code in `master` (most of it
was mechanical except for the fact that since the last commit on that
branch we have gotten rid of Lisp_Misc and we moved to pdumper).
Thanks! I have been waiting for this for years.
I'm getting ready to install this in `master`, so I'd encourage people
to try this code as much as possible to try and weed out the most
glaring problems before it hits master. The code generally looks good,
but it touches some quite "core" code in the redisplay (with lots of
off-by-one opportunities) and in the memory management (with
opportunities for crashes and memory leaks).
I tried with my Emacs config and after some fiddling Emacs crashed during helm search via helm-org-ql (a lot of regexp searching).
I was unable to trigger the crash using unoptimized build, so just giving a heads-up.
Best,
Ihor
