I thought gcc would would for no good reason plain refuse to use global pointer optimization with ELF - but I was wrong, just tested it again. I also noticed that older gcc would emit initialized data to .data with -G even though small data should go to .sdata. Won't work by just enabeling for the kernel though. The kernel has it's own idea of how to use the $gp register. Ralf
