When we implemented the FMAXQV and FMINQV insns we accidentally inverted the sense of the FPCR.AH test, so we gave the AH=1 behaviour when FPCR.AH was zero, and vice-versa. (The difference is limited to hadling of negative zero and NaN inputs.)Fixes: 1de7ecfc12d05 ("target/arm: Implement FADDQV, F{MIN, MAX}{NM}QV for SVE2p1") Signed-off-by: Peter Maydell <peter.mayd...@linaro.org> --- target/arm/tcg/translate-sve.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/target/arm/tcg/translate-sve.c b/target/arm/tcg/translate-sve.c index fc76624b5a1..2ed440aff15 100644 --- a/target/arm/tcg/translate-sve.c +++ b/target/arm/tcg/translate-sve.c @@ -4020,7 +4020,7 @@ static gen_helper_gvec_3_ptr * const fmaxqv_ah_fns[4] = { gen_helper_sve2p1_ah_fmaxqv_s, gen_helper_sve2p1_ah_fmaxqv_d, }; TRANS_FEAT(FMAXQV, aa64_sme2p1_or_sve2p1, gen_gvec_fpst_arg_zpz, - (s->fpcr_ah ? fmaxqv_fns : fmaxqv_ah_fns)[a->esz], a, 0, + (s->fpcr_ah ? fmaxqv_ah_fns : fmaxqv_fns)[a->esz], a, 0, a->esz == MO_16 ?
