[Bug target/63347] m68k misoptimisation with -fschedule-insns


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63347

--- Comment #7 from Jonathan Larmour <jifl-bugzilla at jifvik dot org> ---
I have also now submitted bug 64233 which is about a different testcase which
also gets misoptimised. This may or may not be related, but could well be since
-fschedule-insns is what makes a difference, and a 'tst' disappears (although
there may be more going wrong with that testcase).

Hopefully this will make it easier for someone to work on fixing this, which I
would be very grateful for! Right now, I can't consider the coldfire tools
robust enough to safely use for production code which is unfortunate :-(.

So if anyone could spend some time looking at this bug or bug 64233, that would
be great, thanks!
