--- Comment #8 from Richard Sandiford <rsandifo at gcc dot gnu.org> --- > I don't know if this kind of -msve-vector-bits calling is supported, IMO no. The -msve-vector-bits setting is assumed to be fixed throughout compilation. It's for that reason that we don't support setting the vector length using a function attribute. > but it doesn't ICE without LTO so if it's not supported we should > at least have a way of gracefully erroring out Agreed.
