--- Comment #11 from David Edelsohn <dje at gcc dot gnu.org> --- tree VRP threader : 0.25 ( 2%) 0.03 ( 1%) 0.76 ( 1%) 7804k ( 2%) Despite that report output, prior to the two patches ending with ef1e524fd87a679f5da06116029c66a84daac80 "Remove old VRP jump threader code" and "Replace VRP threader with a hybrid forward threader.", I was able to compile the testcase with an AIX limit of 1.25GB data size and now I need 2.25GB. In other words, I don't need the entire patch series or even the cleanup patch, just the replace VRP and remove old VRP patches.
