--- Comment #17 from Vadim Zeitlin <vz-gcc at zeitlins dot org> --- I've just subscribed to this bug because we see bug slow downs in our project when switching from 8.3 to 10.2 (89% slower in an important use case, 30% slowdown more or less across the board), without any other changes. We don't have any simple test showing this (yet), but there is definitely something very wrong here and I don't think it should be closed. FWIW in our case using -O3 doesn't help (it does make the code marginally faster, but improvement of <0.01% is not worth 10% higher build time).
