Anyways there's something problematic: FMA is slow with C2 disabled. In Panama Vector mode we detect this earlier and fallback to scalar variant. But with this patch the scalar variant is also slow because it uses big decimal. I have not checked this (we have no logging in scalar mode), but from other hotspot options the C2 options are invalid when C2 is not used. I just mention this here. Maybe we should move the panama C2 detection also as a boolean to Constants. -- This is an automated message from the Apache Git Service.
