Unfortunately that's also a very common error source in quite a few
packages, which then only fail on m68k.
We've found GCC option -malign-int for m68k. Citing from the manual:
-malign-int
-mno-align-int
Control whether GCC aligns "int", "long", "long long", "float",
"double", and "long double" variables on a 32-bit boundary
(-malign-int) or a 16-bit boundary (-mno-align-int). Aligning
variables on 32-bit boundaries produces code that runs somewhat
faster on processors with 32-bit busses at the expense of more mem-
ory.
Warning: if you use the -malign-int switch, GCC will align struc-
tures containing the above types differently than most published
application binary interface specifications for the m68k.
Can the issue with alignment of the structure be resolved using this
option? Or this option isn't recommended to use?
