From c128d39edeff337220fc536a3e935bcba01ecb49 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Wed, 30 Oct 2024 15:35:38 +1100 Subject: [PATCH] target/riscv: Fix vcompress with rvv_ta_all_1s vcompress packs vl or less fields into vd, so the tail starts after the last packed field. This could be more clearly expressed in the ISA, but for now this thread helps to explain it: https://github.com/riscv/riscv-v-spec/issues/796 Signed-off-by: Anton Blanchard Reviewed-by: Daniel Henrique Barboza Reviewed-by: Alistair Francis Message-ID: <20241030043538.939712-1-antonb@tenstorrent.com> Signed-off-by: Alistair Francis --- target/riscv/vector_helper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/target/riscv/vector_helper.c b/target/riscv/vector_helper.c index 072bd444b1..ccb32e6122 100644 --- a/target/riscv/vector_helper.c +++ b/target/riscv/vector_helper.c @@ -5132,7 +5132,7 @@ void HELPER(NAME)(void *vd, void *v0, void *vs1, void *vs2, \ } \ env->vstart = 0; \ /* set tail elements to 1s */ \ - vext_set_elems_1s(vd, vta, vl * esz, total_elems * esz); \ + vext_set_elems_1s(vd, vta, num * esz, total_elems * esz); \ } /* Compress into vd elements of vs2 where vs1 is enabled */
