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.
