[llvm-dev] [RFC][ORC] Revisiting Bug 23991

[Min-Yih Hsu via llvm-dev]

Hi all,

I would like to start another discussion on bug 23991 (https://bugs.llvm.org/show_bug.cgi?id=23991 <https://bugs.llvm.org/show_bug.cgi?id=23991>), regarding the missing reregistration of EH frames in ORCv2.

Compared to the time where the bugzilla thread was created, I think the structure of ORCv2 is fairly stable now. So I try to create a small patch trying to fix that: https://reviews.llvm.org/D71683 <https://reviews.llvm.org/D71683>

My concern is that whether this is the proper place to put the deregistration logic. And whether we should put a note to remind future MemoryManager implementations to take care of the deregistration since it’s not suitable to put deregistration in MemoryManager’s dtor as explained in the code review description.

B.R.
