Modified files:
sys/boot/common Makefile.inc
Added files:
sys/boot/common load_elf.c
Log:
ELF loader, part 1. It works with ELF kernels generated on the i386
so far, and should probably be able to be made to work for the alpha
without too much trouble once it's connected up and my assumptions tested.
I think (but have not tested) it will also load "old" ELF kernels that
were not linked with DYNAMIC headers.
The module glue is yet to come. (oh fun.. :-)
It does not explicitly load symbols [yet]. The _DYNAMIC data contains a
runtime symbol set that ddb can use via ddb/db_kld.c. It'll be missing
some detail that stabs normally provides (eg: number of args to a function,
line numbers, etc). On the other hand, those minimal symbols will always
be available even on a stripped kernel.
This is mostly stolen from load_aout.c with some ideas from
alpha/libalpha/elf_freebsd.c.
