This is where I disagree other arch as mips and other will also need to move away from the needs to include libgcc to be really toolchain independant
I do think it's really important for U-Boot be able to have full control to have a functions embedded into. So stop to have libgcc include by default will really reflect it Best Regards, J. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
