Ahh, thanks!
I've just found my own way of iterating via a script at
https://github.com/nordlow/scripts/blob/master/dmd-own
that (re)compiles druntime and phobos and then compiles my GC
test application using toolchain in around 7 secs on my 2 year
old laptop. I'll stick to that for now.
This assumes the home-directory structure
~/Work/dmd ~master
druntime ~dmitry-gc
phobos ~master
. The playground for my GC experiments will be
https://github.com/nordlow/druntime/blob/dmitry-gc/src/gc/impl/dmitry/gc.d
So far I've only described my plan and added a set of debug
prints.
You're very welcome to comment and destroy my plan. I'm uncertain
of what kinds of locking (if any) that is needed for a
thread-local GC allocation (non-mutex I suppose). Please
elaborate on the subject if you have any experience with
thread-local GCs.
Would you be interested in making this a druntime PR so you can
make comments?
