digitalmars.D - [SAOC 25] improve importC weekly update 17
Hi all, This week I was able to fix building static library with importC on static functions. see issue : https://github.com/dlang/dmd/issues/22153. in my investigations, I realized when static function redeclarations are encountered where the later one is a definition, the replacement does wasn't reflecting in backend. so the backend was always picking the function with no body. I had to transfer the functions definitions to the declarations for functions that needed internal linkage and resolutions. and that fixed it. see PR: https://github.com/dlang/dmd/pull/22360#pullrequestreview-3642954373 I tested with several libraries compiling them `-lib`. I also caught an extra issue that needed fixing. I realized that when the static function is referenced globally by its address, it is still not resolved in backend, but when it is referenced by its address locally, it works fine. this was caught when testing zlib library that use const initializers to reference functions. see issue: https://github.com/dlang/dmd/issues/22365. looking through it and I hope I get it fixed soon.

As a potential idea - is to have a separate "importC CI" which will test different types of building (including static) with GitHub Actions

I’m now about to fetch some libraries that I’ve tested locally and then move them there with dmd-current. At least I think I have been able to clear some basic and important needed fixes.
