--- Comment #8 from Martin Jambor <jamborm at gcc dot gnu.org> --- The issue actually started with my r8-344-2bba75411e1 and it is basically a perfect SRA bomb, it makes SRA sub-access propagation accross assignments create gazillions of accesses and then replacements, because they facilitate forward propagation (and as ccp3 dumps shows, they do). I already have a patch that simply limits the number of replacements to a param, defaulting to 128, which makes the testcase compilation finish in about 9 seconds on my machine. However, SRA analysis still takes 7 seconds of that, so I'm looking at capping the propagation earlier. That takes more book-keeping, so at least for backports, I'd like to use the simpler approach on released branches.
