lld 9.0 appears to be optimizing out ctor

Open jaynus opened this issue 5 years ago • 3 comments

This seems possibly related to dtolnay/inventory#11.

After upgrading to LLVM 9.0.1, it appears my registrations with the inventory crate, using ctor, have dissapeared. Reverting back to LLVM 8.0 resolves the issue.

Specifically, it appears if code in the module is not used, ctor does not run. This wasn't previously the case, so appears to be a new optimization cutting out the registrations from unused modules.

This sounds a bit like #27

I should clarify; in my case, these are 2 seperate module files in the same crate

Is this still an issue these days?

Closing for now -- #280 may have a solution for +nightly users.
