I didn't close it because I wanted to see updated benchmark numbers. Either
I'll grab the benchmark, or if somebody else posts the latest numbers, we can
close it or keep open depending on that.

So the original report is fixed (-O3 -march-native). But adding -ffast-math
still ends up regressing.
At this point it's probably appropriate to re-target to GCC 8.

So, Richard, any thoughts on what can be done split paths to avoid this?

Could you please have a look also to c++ and lto: this is what I get on my

Has somebody the benchmark around to retry with current trunk, with
-f{,no-}split-paths and compare that to some older trunk and gcc6?
