[avr-libc-dev] [bug #38765] avr/iotnx5.h defines USI_OFL_vect not USI_OVERFLOW_vect

[Joerg Wunsch]

Update of bug #38765 (project avr-libc):

                  Status:                    None => Wont Fix               
             Assigned to:                    None => joerg_wunsch           
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

Our policy is to make the interrupt vector names match the
Atmel XML file, and the datasheet (to whatever is possible
in terms of a valid C name, e.g. by replacing spaces by
underscores).

Since the datasheets and XML files of the various USI-equipped
AVRs don't agree on each other, our vector names don't either.
We did invent our own (self-consistent wrt. avr-libc) vector
names in the past, but this idea eventually turned out to be
unmaintainable, so as a matter of policy, we switched to
automatically generating them from the XML files.

The following devices appear to use OSI_OVF:

ATtiny87/167, ATtiny*4(A), ATtiny*5, ATtiny26, ATtiny*61(A),
ATtiny43U

The following devices appear to use OSI_OVERFLOW:

ATtiny2313(A), ATtiny4313, ATmega{16,32,64}{5,9}{,0}(PA)
