These tests have also regressed for mmix-knuth-mmixware 132182 - 136827, so if
it's a target-specific thing that went wrong (assuming it's the same reason;
there are two more regressions in that range but that's it

This is really not a task for SRA but for struct copy propagation (which we

As this testcase was for SRA you can either XFAIL it for avr or see if the
