Do you have a testcase where this change can result in better generated
code. If so please add that testcase. It's OK if it's ARM specific.
Hi Jeff,
Last time I tried I couldn't reduce the code to a small testcase but if I
remember
well it was mostly due to the problem of finding a good test for creduce
(zero extension is not unique enough). I'll try again with a more manual
approach
and get back to you.
OK. No need for heroics -- give it a shot, but don't burn an insane
amount of time on it. If we can't get to a reasonable testcase, then so
be it.
