That's dangerous because the compiler might use %esi in the post_coreboot() function. If you really want to do this, you should move %esp to %eax and declare the stack pointer as an argument to post_coreboot() and then pass the argument to the inline asm. -Kevin -- coreboot mailing list [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
