There seems to be a memory consumption issue on 32 bit hosts after the
hybrid threader patchset. I'm having a hard time reproducing, and in
the process I've noticed that the threader is using the TV_TREE_VRP
timer. Having a distinct one could help diagnose this and other
issues going forward.
Jeff, if you think this could help, I'd like to push this to trunk, but
if not, I'm perfectly happy attaching it to the 2 PRs for now. :)
gcc/ChangeLog:
* timevar.def (TV_TREE_VRP_THREADER): New.
* tree-vrp.c: Use TV_TREE_VRP_THREADER for VRP threader pass.
