--- Comment #20 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Georg-Johann Lay <g...@gcc.gnu.org>: https://gcc.gnu.org/g:1c54f35e65c2b7f9f164b6593e288637688ff7a7 commit r13-7360-g1c54f35e65c2b7f9f164b6593e288637688ff7a7 Author: Triffid Hunter <triffid.hun...@gmail.com> Date: Sat May 20 07:50:00 2023 +0200 target/105753: Fix ICE in add_clobbers due to extra PARALLEL in insn. This patch removes the superfluous parallel in [u]divmod patterns in the AVR backend. Effect of extra parallel is that add_clobbers reaches gcc_unreachable() because the clobbers for [u]divmod are missing. If an insn has multiple parts like clobbers, the parallel around the parts of the insn pattern is implicit. gcc/ PR target/105753 Backport from 2023-05-20 https://gcc.gnu.org/r14-1016 * config/avr/avr.md (divmodpsi, udivmodpsi, divmodsi, udivmodsi): Remove superfluous "parallel" in insn pattern. ([u]divmod<mode>4): Tidy code. Use gcc_unreachable() instead of printing error text to assembly. gcc/testsuite/ PR target/105753 Backport from 2023-05-20 https://gcc.gnu.org/r14-1016 * gcc.target/avr/torture/pr105753.c: New test.
