--- Comment #57 from Andrew Macleod <amacleod at redhat dot com> --- FWIW, on my last run, enabling early VRP sped up my -O1 compilation by a fair amount. total compilation dropped from 480 seconds to 380 seconds... It took 2.5 seconds to run, and im going to guess might have cleaned the code up somewhat. Might be worth looking at a Fast VRP pass at -O1? I'm not sure how/where to add NEXT_PASS (pass_fast_vrp); to run it at -O1, but it can be easily experimented with via --enable-tree-evrp --param=vrp-block-limit=1 which will always run Fast VRP as the EVRP pass.
