Yes, I've seen how wired the GC is in the ocaml sources. I had used the
Boehm GC in a compiler project (not for the generated code but the
compiler),
do you mean that one would have to disable most optimizations in the ocaml
bytecode
compiler to make such a hypothetical bytecode-to-C compiler work with a C
GC, or am I missing something crucial? It's great to be able to learn from
actual
ocaml compiler writers, BTW, your comments are much appreciated.
