[U-Boot] question: U-boot linking against libgcc
Hello Wolfgang,
In U-boot I see that it links against libgcc. Why is this? I believe this relation should not be needed. I could provide a patch to remove this relation...
Kind Regards,
Remy

Because the GNU compiler references code form it's library.

Linux works fine without libgcc. I only had to add three 64-bit shift routines for avr32.
And as an added bonus, you get a linker error if you introduce an open-coded 64-bit division by mistake :-)

It's simple to do it on arm
