            Bug ID: 71791
           Summary: [ARM] missed the implementation of ACLE intrinsics
                    vminnm_f32/vminnmq_f32/vmaxnm_f32/vmaxnmq_f32
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Keywords: xfail
          Severity: minor
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jiwang at gcc dot gnu.org
  Target Milestone: ---
            Target: arm*

The are listed on at least ACLE 2.0 for ARM32, but GCC ARM port hasn't
implemented them.

There is backend pattern for them fmax/fmin but they are standard names without
"neon_" prefix, the current neon intrinsic builtins .def for ARM seems force
the prefix to be with "neon_", so there might needs minor tweak on the macro
expand.
