Subject: [PATCH, MIPS] Align _end symbol to at least 4 in all MIPS scripts
Date: Tue, 30 Jul 2019 00:00:00 -0000 [thread overview]
Message-ID: <1564444804-9846-1-git-send-email-fshahbazker@wavecomp.com> (raw)
In-Reply-To: <mpt36jl1zoa.fsf@arm.com>
Left-over part of commit 84b2a020daa17d8ee5c9ec979c3d56f95e69573b
The _end marker must be aligned to 4-bytes to ensure that the last
element written does not reach beyond the address of _end. This is
also necessary as the termination condition is an equality test
instead of an ordered test so (_end - _fbss) must be a multiple of
4-bytes. The alignment is already correct for mti*.ld files, fix
it for all remaining MIPS scripts that don't already align to at
least 4.
