--- Comment #7 from Andrew Macleod <amacleod at redhat dot com> --- I think fixing 114855 will probably resolve this one too. Its a more "managable" test case. I'm trying to have a look, but I am off next week so it isn't imminent. Meanwhile the "workaround" might be to use '-fno-tree-dominator-opts' and maybe '-fno-thread-jumps -fno-tree-reassoc'. I don't know if the no-tree-reassoc is still necessary, but when I was looking at 114855 for VRP it died in reassociation if I turned off thread-jumps.
