Like the others said, the patch does not change the default behavior for
unhandled interrupts - they still branch to __bad_interrupt. The user
would have to explicitly use the --shrink-ivt option to change that -
at which point, I guess he should be knowing what he's doing.
For what it's worth, I asked about the usefulness of this in avr freaks
a while back
(http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=128193)
and most people thought it would be useful, provided it can be
controlled by a command line switch. This "optimization" was also
requested when Johann asked for features for the compiler.
