--- Comment #9 from abebeos at lazaridis dot com ---
Looking into this since a few days. All looks that B.S. statements seem valid:
https://gcc.gnu.org/pipermail/gcc/2020-April/000455.html
The bounty goal should be similar to "Convert m68k to not use cc0":
=> Convert avr to not use cc0 (thus it can be included to gcc11).
So, the requirements would be:
- must not use cc0
- keep generated code as much as possible identical (= avoid trouble and
follow-up work)
- use of MODE_CC constructs is optional
-
P.S.: It looks like previous work on this from "pipcet" got stuck, possibly
exactly due to the complexity that a larger one-chunk-change introduces,
especially when the resulting generated code changes much:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92729#c6
So, if it's ok for the backers, reduce the scope of the bounty to "just get avr
into gcc11 and keep generated code as much as possible unchanged".
