But as implemented those shouldn't accumulate a lot of time because other timevars are pushed for them. I think you want to instead split TV_PHASE_OPT_GEN into TV_PHASE_OPT_GIMPLE TV_PHASE_IPA and TV_PHASE_RTL which probably can be easiest managed by the pass manager pushing/popping those appropriately depending on the pass kind that is invoked?
