Except I don't think it's an optimization performance-wise. But if you enable -Os then I would expect it to use rep stosb. > It also doesn't address why coreboot has a functions when we could > use gcc intrinsic that should be optimized for the architecture > they are built for. Good point! I guess we rolled our own to be less dependent on gcc. I think it would be OK to use gcc's implementations though. //Peter -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
