The bug is in src/arch/i386/boot/boot.c. The inline assembly in jmp_to_elf_entry uses the "g" flag to pass in parameters. However, "g" allows gcc to use stack relative addressing of parameters. Unfortunately, the inline assembly modifies %esp - and thus the stack relative values become incorrect. As a guess, without -fomit-frame-pointer, gcc would pass use %ebp relative values and this wouldn't trigger - but regardless it is still a bug. -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
