           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target

Testcase

#include <arm_neon.h>

int8x8_t
f_vld1_lane (int8_t * p, int8x8_t v)
{
  int8x8_t res;
  res = vld1_lane_s8 (p, v, 1);
  return res;
}

$ aarch64-none-elf-gcc -S test.c
