so, I wanted to use 64-bit integers in my code and my linker gave me an odd error, something like "__udivi3 is not defined" so I looked it up and libgcc is used by gcc to do things there isn't an instruction for. so I figured it was just a simple binary that had no other dependencies and that I could just link libgcc.a. it seems to have worked quite well but I want to make sure it's not going to bite me in the future.

has anyone ever had an issue with linking libgcc into your kernel?

I'm using libgcc for things like 64 bit arithmetics or integer division on some architectures and it never caused me any problems. I guess it's very common to do that.

I haven't needed in my kernel yet, but I do use it in my boot loader. No problems at all.

alright, sounds like it should work then thanks guys
