OK with a proper ChangeLog after bootstrap / testing.
It's also OK to backport this to the GCC 10 branch if powerpc
folks want to restore GIMPLE cunroll behavior for their target.
Yes please! (But first make sure it works as expected, no fallout,
etc.)
Thanks to both of you,
Segher
Thanks all for your comments and suggestions!
The patches were committed to trunk.
I thinking it would still need to tune cunroll to avoid peeling complex
loop(e.g. early exits loop) or tune the params of cunroll.
