Subject: [PATCH 2/7] mkimage: Replace hardcoded 0x400 in R_ARM_ABS32 relocation
Date: Sun, 29 Dec 2013 18:47:31 +0000 [thread overview]
Message-ID: <1388342856-18317-2-git-send-email-ijc@hellion.org.uk> (raw)
In-Reply-To: <1388342839.32105.25.camel@hastur.hellion.org.uk>
In http://lists.gnu.org/archive/html/grub-devel/2013-04/msg00034.html Leif
suggested that this should actually be "SUFFIX (entry_point)" saying:
_start gets bumped down a bit, so all relative relocations need to follow,
and then I "un-adjust" for the absolutes. Not too proud of that bit of code.
I think this "bumping down" actually comes from the image type's vaddr_offset
and therefore it is more correct to adjust by this amount.
