From fa8b4468e0d124bec0fdbfc0a168bd8c377b08ec Mon Sep 17 00:00:00 2001 From: Jonathan Wakely Date: Wed, 7 Jun 2023 13:01:36 +0100 Subject: [PATCH] libstdc++: Fix some tests that fail with -fno-exceptions libstdc++-v3/ChangeLog: * testsuite/18_support/nested_exception/rethrow_if_nested-term.cc: Require effective target exceptions_enabled instead of using dg-skip-if. * testsuite/23_containers/vector/capacity/constexpr.cc: Expect shrink_to_fit() to be a no-op without exceptions enabled. * testsuite/23_containers/vector/capacity/shrink_to_fit.cc: Likewise. * testsuite/ext/bitmap_allocator/check_allocate_max_size.cc: Require effective target exceptions_enabled. * testsuite/ext/malloc_allocator/check_allocate_max_size.cc: Likewise. * testsuite/ext/mt_allocator/check_allocate_max_size.cc: Likewise. * testsuite/ext/new_allocator/check_allocate_max_size.cc: Likewise. * testsuite/ext/pool_allocator/check_allocate_max_size.cc: Likewise. * testsuite/ext/throw_allocator/check_allocate_max_size.cc: Likewise. --- .../18_support/nested_exception/rethrow_if_nested-term.cc | 2 +- .../testsuite/23_containers/vector/capacity/constexpr.cc | 8 ++++++++ .../23_containers/vector/capacity/shrink_to_fit.cc | 4 ++++ .../ext/bitmap_allocator/check_allocate_max_size.cc | 2 ++ .../ext/malloc_allocator/check_allocate_max_size.cc | 2 ++ .../testsuite/ext/mt_allocator/check_allocate_max_size.cc | 2 ++ .../ext/new_allocator/check_allocate_max_size.cc | 2 ++ .../ext/pool_allocator/check_allocate_max_size.cc | 2 ++ .../ext/throw_allocator/check_allocate_max_size.cc | 1 + 9 files changed, 24 insertions(+), 1 deletion(-) diff --git a/libstdc++-v3/testsuite/18_support/nested_exception/rethrow_if_nested-term.cc b/libstdc++-v3/testsuite/18_support/nested_exception/rethrow_if_nested-term.cc index 5913392bd461..3bfc7ab99436 100644 --- a/libstdc++-v3/testsuite/18_support/nested_exception/rethrow_if_nested-term.cc +++ b/libstdc++-v3/testsuite/18_support/nested_exception/rethrow_if_nested-term.cc @@ -1,5 +1,5 @@ // { dg-do run { target c++11 } } -// { dg-skip-if "" { *-*-* } { "-fno-exceptions" } } +// { dg-require-effective-target exceptions_enabled } #include #include diff --git a/libstdc++-v3/testsuite/23_containers/vector/capacity/constexpr.cc b/libstdc++-v3/testsuite/23_containers/vector/capacity/constexpr.cc index 92c23035e4f3..f102e78425b9 100644 --- a/libstdc++-v3/testsuite/23_containers/vector/capacity/constexpr.cc +++ b/libstdc++-v3/testsuite/23_containers/vector/capacity/constexpr.cc @@ -89,11 +89,19 @@ test_shrink_to_fit() std::vector v; v.reserve(9); v.shrink_to_fit(); +#if __cpp_exceptions VERIFY( v.capacity() == 0 ); +#else + VERIFY( v.capacity() == 9 ); +#endif v.reserve(9); v.resize(5); v.shrink_to_fit(); +#if __cpp_exceptions VERIFY( v.capacity() == v.size() ); +#else + VERIFY( v.capacity() == 9 ); +#endif return true; } diff --git a/libstdc++-v3/testsuite/23_containers/vector/capacity/shrink_to_fit.cc b/libstdc++-v3/testsuite/23_containers/vector/capacity/shrink_to_fit.cc index a8cede2278d8..6542b5fd39f6 100644 --- a/libstdc++-v3/testsuite/23_containers/vector/capacity/shrink_to_fit.cc +++ b/libstdc++-v3/testsuite/23_containers/vector/capacity/shrink_to_fit.cc @@ -30,7 +30,11 @@ void test01() v.push_back(1); VERIFY( v.size() < v.capacity() ); v.shrink_to_fit(); +#if __cpp_exceptions VERIFY( v.size() == v.capacity() ); +#else + VERIFY( v.size() < v.capacity() ); +#endif } int main() diff --git a/libstdc++-v3/testsuite/ext/bitmap_allocator/check_allocate_max_size.cc b/libstdc++-v3/testsuite/ext/bitmap_allocator/check_allocate_max_size.cc index 712489f26a92..e523bb8f6c2c 100644 --- a/libstdc++-v3/testsuite/ext/bitmap_allocator/check_allocate_max_size.cc +++ b/libstdc++-v3/testsuite/ext/bitmap_allocator/check_allocate_max_size.cc @@ -16,6 +16,8 @@ // with this library; see the file COPYING3.
