Hi Arnaud, LiveInterval::markNotSpillable() sets the live interval's spill weight to infinity. For well-formed PBQP graphs (i.e. ones that have some finite-cost solution), PBQP should never chose to spill such an interval. The two possibilities for this crash are that the input graph has no finite-cost solution, or that you've exposed a bug in the PBQP solver. >From memory your target

Hi All, I finally had a chance to get back to my pbqp trials, now using the 3.0 release. I still hit the same assert : "Attempting to spill already spilled value." This is triggered because in RegAllocPBQP::mapPBQPToRegAlloc, a vreg node is either : - a physical register (problem.isPRegOption(vreg, alloc)), - or a spill (problem.isSpillOption(vreg, alloc)) The problem is that pass

...re all handled by the 2 passes above.
