Good point. I should have thought of that.
So what's the point of #pragma pack(2) or #pragma option align=packed ?
It's not really too useful for 68K. Also, some 68K architectures can run
faster with 32-bit values on 4-byte alignment, and this will relax that if
you're in that mode... but this doesn't matter for the plain 68000 CPU used
in the original Palm devices.
And what is gcc doing to allow this ?
GCC will generate the slow byte-by-byte access code if needed. CodeWarrior
will not.
