Andreas, Jeff,
The documentation for `-malign-int' on m68k hints that 16-bit int
alignment was the prominent alignment chosen by m68k ABI's of the era.
Why is 16-bit int alignment the default for m68k in gcc?
Which ABIs influenced this decision?
Should Coldfire targets default to 16 or 32-bit int alignment?
Cheers,
Carlos.
