commit ab6b37ac32ddf2f2f11f800a770170814f5cbb8b
Author: Mark Wielaard <mark@klomp.org>
Date: Tue Oct 24 14:23:30 2017 +0200
backends: Ignore GCC8 -Wpacked-not-aligned for m68k_corenote.c.
The GCC8 -Wpacked-not-aligned warns if a structure field with explicit
padding in a packed structure will be misaligned. m68k prstatus core
notes are described by a packed structure which has such aligned structure
fields.
