Subject: [newlib-cygwin] Align _end symbol to at least 4 in all MIPS scripts
Date: Tue, 30 Jul 2019 07:38:00 -0000 [thread overview]
Message-ID: <20190730073827.52610.qmail@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=6661a67747c14cfa7ac91458914037ee296fcd1e
commit 6661a67747c14cfa7ac91458914037ee296fcd1e
Author: Faraz Shahbazker <fshahbazker@wavecomp.com>
Date: Tue Jul 30 00:00:25 2019 +0000
Align _end symbol to at least 4 in all MIPS scripts
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.
