--- Comment #2 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- Maybe it's much of a muchness, but would it work instead to bail out for wrapping types at the top of split_constant_offset_1 and remove the check for trapping from the CASE_CONVERT code? It seems that in practice split_constant_offset_1 can't handle any trapping types.
