Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> --- Fixed - I do wonder why this doesn't fail on branches, we still have the same V foo (V v) { V _2; ;; basic block 2, loop depth 0 ;; pred: ENTRY _2 = MEM[(V *)&v + -1B]; return _2; there upon RTL expansion. Ah, it's because tree_could_trap_p now uses bit_field_offset, the very problem is on branches as well (maybe it's no problem after all).
