Hi all, In GCC13/12, there is no _mm_avx512_setzero_ps/d since it is introduced in GCC14.
Fix the backport issue as obvious in: https://gcc.gnu.org/pipermail/gcc-regression/2024-July/080385.html Thx, Haochen gcc/ChangeLog: * config/i386/avx512dqintrin.h (_mm_reduce_round_sd): Use _mm_setzero_pd instead of _mm_avx512_setzero_pd. (_mm_reduce_round_ss): Use _mm_setzero_ps instead of _mm_avx512_setzero_ps. --- gcc/config/i386/avx512dqintrin.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/gcc/config/i386/avx512dqintrin.h b/gcc/config/i386/avx512dqintrin.h index 4383ff14670..82f4acc7d2e 100644 --- a/gcc/config/i386/avx512dqintrin.h +++ b/gcc/config/i386/avx512dqintrin.h @@ -2840,7 +2840,7 @@ _mm512_fpclass_ps_mask (__m512 __A, const int __imm) #define _mm_reduce_round_sd(A, B, C, R) \ ((__m128d) __builtin_ia32_reducesd_mask_round ((__v2df)(__m128d)(A), \ - (__v2df)(__m128d)(B), (int)(C), (__v2df) _mm_avx512_setzero_pd (), \ + (__v2df)(__m128d)(B), (int)(C), (__v2df) _mm_setzero_pd (), \ (__mmask8)(-1), (int)(R))) #define _mm_mask_reduce_round_sd(W, U, A, B, C, R) \ @@ -2869,7 +2869,7 @@ _mm512_fpclass_ps_mask (__m512 __A, const int __imm) #define _mm_reduce_round_ss(A, B, C, R) \ ((__m128) __builtin_ia32_reducess_mask_round ((__v4sf)(__m128)(A), \ - (__v4sf)(__m128)(B), (int)(C), (__v4sf) _mm_avx512_setzero_ps (), \ + (__v4sf)(__m128)(B), (int)(C), (__v4sf) _mm_setzero_ps (), \ (__mmask8)(-1), (int)(R))) #define _mm_mask_reduce_round_ss(W, U, A, B, C, R) \ -- 2.31.1
