Ok for trunk, sorry for the delay.

Thanks. Richard has moved the passes a bit since then, but I still have

exactly one spot where the testsuite is ok :-) I need strlen to be
after
dom (for calloc.C) and before vrp (for several strlenopt-*.c). I'll
commit
it tomorrow if there aren't any comments on the pass placement.

But vrp does not run at -O1 - does strlenopt?

    { OPT_LEVELS_2_PLUS_SPEED_ONLY, OPT_foptimize_strlen, NULL, 1 },
    { OPT_LEVELS_2_PLUS, OPT_ftree_vrp, NULL, 1 },

So that's just a missed optimization at -Os, I guess.
