This patch adds support for the immediate forms of SVE SMAX, SMIN, UMAX and UMIN. SMAX and SMIN take the same range as MUL, so the patch basically just moves and generalises the existing MUL patterns. 2019-08-14 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/constraints.md (vsb): New constraint. (vsm): Generalize description. * config/aarch64/iterators.md (SVE_INT_BINARY_IMM): New code iterator. (sve_imm_con): Handle smax, smin, umax and umin.
