From f8e4412b047e4f075b628203fda84e2b4e6842cc Mon Sep 17 00:00:00 2001 From: chenxiaolong Date: Fri, 5 Jan 2024 11:43:29 +0800 Subject: [PATCH] LoongArch: testsuite:Give up the detection of the gcc.dg/fma-{3, 4, 6, 7}.c file. On the LoongArch architecture, the above four test cases need to be waived during testing. There are two situations: 1. The function of fma-{3,6}.c test is to find the value of c-a*b, but on the LoongArch architecture, the function of the existing fnmsub instruction is to find the value of -(a*b - c); 2. The function of fma-{4,7}.c test is to find the value of -(a*b)-c, but on the LoongArch architecture, the function of the existing fnmadd instruction is to find the value of -(a*b + c); Through the analysis of the above two cases, there will be positive and negative zero inequality. gcc/testsuite/ChangeLog * gcc.dg/fma-3.c: The intermediate file corresponding to the function does not produce the corresponding FNMA symbol, so the test rules should be skipped when testing. * gcc.dg/fma-4.c: The intermediate file corresponding to the function does not produce the corresponding FNMS symbol, so skip the test rules when testing. * gcc.dg/fma-6.c: The cause is the same as fma-3.c. * gcc.dg/fma-7.c: The cause is the same as fma-4.c --- gcc/testsuite/gcc.dg/fma-3.c | 2 +- gcc/testsuite/gcc.dg/fma-4.c | 2 +- gcc/testsuite/gcc.dg/fma-6.c | 2 +- gcc/testsuite/gcc.dg/fma-7.c | 2 +- 4 files changed, 4 insertions(+), 4 deletions(-) diff --git a/gcc/testsuite/gcc.dg/fma-3.c b/gcc/testsuite/gcc.dg/fma-3.c index 699aa2c9530..6649b54b6f9 100644 --- a/gcc/testsuite/gcc.dg/fma-3.c +++ b/gcc/testsuite/gcc.dg/fma-3.c @@ -12,4 +12,4 @@ f2 (double a, double b, double c) return c - a * b; } -/* { dg-final { scan-tree-dump-times { = \.FNMA \(} 2 "widening_mul" { target scalar_all_fma } } } */ +/* { dg-final { scan-tree-dump-times { = \.FNMA \(} 2 "widening_mul" { target { scalar_all_fma && { ! loongarch*-*-* } } } } } */ diff --git a/gcc/testsuite/gcc.dg/fma-4.c b/gcc/testsuite/gcc.dg/fma-4.c index bff928f1fac..f1701c1961a 100644 --- a/gcc/testsuite/gcc.dg/fma-4.c +++ b/gcc/testsuite/gcc.dg/fma-4.c @@ -12,4 +12,4 @@ f2 (double a, double b, double c) return -(a * b) - c; } -/* { dg-final { scan-tree-dump-times { = \.FNMS \(} 2 "widening_mul" { target scalar_all_fma } } } */ +/* { dg-final { scan-tree-dump-times { = \.FNMS \(} 2 "widening_mul" { target { scalar_all_fma && { ! loongarch*-*-* } } } } } */ diff --git a/gcc/testsuite/gcc.dg/fma-6.c b/gcc/testsuite/gcc.dg/fma-6.c index 87258cec4a2..9e49b62b6de 100644 --- a/gcc/testsuite/gcc.dg/fma-6.c +++ b/gcc/testsuite/gcc.dg/fma-6.c @@ -64,4 +64,4 @@ f10 (double a, double b, double c) return -__builtin_fma (a, b, -c); } -/* { dg-final { scan-tree-dump-times { = \.FNMA \(} 14 "optimized" { target scalar_all_fma } } } */ +/* { dg-final { scan-tree-dump-times { = \.FNMA \(} 14 "optimized" { target { scalar_all_fma && { ! loongarch*-*-* } } } } } */ diff --git a/gcc/testsuite/gcc.dg/fma-7.c b/gcc/testsuite/gcc.dg/fma-7.c index f409cc8ee3c..86aacad7b90 100644 --- a/gcc/testsuite/gcc.dg/fma-7.c +++ b/gcc/testsuite/gcc.dg/fma-7.c @@ -64,4 +64,4 @@ f10 (double a, double b, double c) return -__builtin_fma (a, b, c); } -/* { dg-final { scan-tree-dump-times { = \.FNMS \(} 14 "optimized" { target scalar_all_fma } } } */ +/* { dg-final { scan-tree-dump-times { = \.FNMS \(} 14 "optimized" { target { scalar_all_fma && { ! loongarch*-*-* } } } } } */
