It has been always the case that additional options not enabled with
any regular -O level gets less testing and more likely has bugs. So for
mission critical functionality I would strongly suggest to stay with -O2
and not try to rely on not thoroughly tested combinations of optimization
options.
So from my point of view, the situation with -ftree-loop-linear is
fine - it's ICEing after all, not producing silently wrong-code. For
experimental options (where
I would include all options not enabled by -O[123s]) known wrong-code bugs
should be fixed.
That's my 2c,
Richard.
