Hi,
Yeah, that's because of the very limited analysis we do in the backend to
detect such cases. In fact
we probably would want to have an OSC break in many of them as well.
For me the testcase appears to work with -O2 on all the -march levels. I think
-O2 would be
preferred because that's what is most frequently used.
Is it OK?
Yes, either with -O2 or the options you have proposed if -O2 doesn't work out
for you.
-O2 did not work reliably for me with different --with_arch settings.
I'm going to commit the -O1 -fschedule-insns version then.
Regards
Robin
