From 8fce31f69bc6800b81eb7f274d6128162f5ec8b1 Mon Sep 17 00:00:00 2001 From: Alexandre Oliva Date: Mon, 27 Jun 2022 10:34:19 -0300 Subject: [PATCH] libstdc++: testsuite: require cmath for exp simd simd_math.h assumes declarations for many C99 functions to be present, that libstdc++ doesn't add to target systems that don't have them in the C library. Add the C99 math requirement to tests for simd features, so that they don't fail because of limitations of the target C library. for libstdc++-v3/ChangeLog * testsuite/experimental/simd/standard_abi_usable.cc: Require cmath support. * testsuite/experimental/simd/standard_abi_usable_2.cc: Likewise. --- libstdc++-v3/testsuite/experimental/simd/standard_abi_usable.cc | 1 + .../testsuite/experimental/simd/standard_abi_usable_2.cc | 1 + 2 files changed, 2 insertions(+) diff --git a/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable.cc b/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable.cc index 4d7e6726951f..1b686d9ca095 100644 --- a/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable.cc +++ b/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable.cc @@ -1,5 +1,6 @@ // { dg-options "-std=c++17 -fno-fast-math" } // { dg-do compile { target c++17 } } +// { dg-require-cmath "" } // Copyright (C) 2020-2022 Free Software Foundation, Inc. // diff --git a/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable_2.cc b/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable_2.cc index a609adaf000b..a0203d0b4238 100644 --- a/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable_2.cc +++ b/libstdc++-v3/testsuite/experimental/simd/standard_abi_usable_2.cc @@ -1,4 +1,5 @@ // { dg-options "-std=c++17 -ffast-math" } // { dg-do compile } +// { dg-require-cmath "" } #include "standard_abi_usable.cc" -- 2.47.2
