--- Comment #6 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- As an update, even with the patch for PR121198 in place, avr-gcc still gives ICE when hard-register costraints are used in avr.md like with the patch https://gcc.gnu.org/bugzilla/attachment.cgi?id=62066 from above. A code that can trigger the ICE is like in the operning post.
