Could you or @stedolan add some description to this PR of how this works, and some indication of what invariants it relies on to work? It's unclear whether this supports e.g. pointers to locals on a parent's stack. |
Sure, I'll probably do this as comments in the code. |

This provides support for local allocations in the presence of algebraic effects.
There aren't presently any clever optimisations, although care is taken to ensure that the code sequences generated by the OCaml compiler for local allocations remain unchanged. This is done by arranging for some of the per-stack locals state to be present at the root of
Caml_statein addition to being stored in thestack_infostructures.Based on #2205.
