August 21, 2020 GCC is getting parallelization and so should DMD | ||||
---|---|---|---|---|
| ||||
It's time we start thinking about preparing for parallelization in DMD now that GCC is getting it [1]. Andrei mentioned this in an interview as early 2014 [2]. A good start is to start moving the `__gshared` declarations into aggregates that are explicitly instantiated in mars.d and then passed as context references into functions constructors. That will be a lot of manual work. However this process can be directed by D's purity checks by adding `pure:` at module top-levels. I've already started experimenting with this at [3] I reckon the greatest obstacle is to sync these changes with all the C/C++ mappings in dmd.

If the patches go in, gdc will get this feature for free. :-)
