            Bug ID: 63950
           Summary: [AArch64] ICE at -O0 on vld1_lane intrinsics
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: alalaw01 at gcc dot gnu.org

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

Seems to be caused by lack of constant propagation at -O0, compiles fine at -O1
and higher.

[AArch64]Fix ICE at -O0 on vld1_lane intrinsics

gcc/:

        * config/aarch64/arm_neon.h (__AARCH64_NUM_LANES, __aarch64_lane *2):
        New.
        (aarch64_vset_lane_any): Redefine using previous, same for BE + LE.
        (vset_lane_f32, vset_lane_f64, vset_lane_p8, vset_lane_p16,
        vset_lane_s8, vset_lane_s16, vset_lane_s32, vset_lane_s64,
        vset_lane_u8, vset_lane_u16, vset_lane_u32, vset_lane_u64): Remove
        number of lanes.
        (vld1_lane_f32, vld1_lane_f64, vld1_lane_p8, vld1_lane_p16,
        vld1_lane_s8, vld1_lane_s16, vld1_lane_s32, vld1_lane_s64,
        vld1_lane_u8, vld1_lane_u16, vld1_lane_u32, vld1_lane_u64): Call
        __aarch64_vset_lane_any rather than vset_lane_xxx.

gcc/testsuite/:

        * gcc.target/aarch64/vld1_lane-o0.c: New test.
