I have a scripted build flow which works nicely for a range of projects and a quite wide range of vivado versions, currently the 2017.2 to 2018.3. For 2018.2 and before I often got warnings
WARNING: [Synth 8-3332] Sequential element (xxx) is unused and will be removed from yyy.
For 2018.3, with an identical build script, I do not see any [Synth 8-3332] messages.
I found the [Synth 8-3332] warnings often useful and thus wonder what happened.
Was that type of warning removed ? If yes, why ?
Or must it be explicitly enabled ?
Thanks in advance for any hint/help, Walter

DId you check that in Vivado 2018.3 those sequential elements are present or not Which were removed in earlier Vivado versions?
If yes, then can you provide a small testcase to check this difference in mulitple Vivado versions at my end?

find attached two projects. Identical sources, one 2017.2 and one 2018.3 project with synthesis step run.
For 2017.2 one gets
For 2018.3 one gets
--> Synth 8-3332 warnings are gone.
