From: Jonathan Wakely Date: Thu, 8 Jun 2023 11:19:26 +0000 (+0100) Subject: libstdc++: Improve tests for emplace member of sequence containers X-Git-Tag: basepoints/gcc-15~8494 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3ec1d76a359542ed4c8370390efa9ee9e25e757f;p=thirdparty%2Fgcc.git libstdc++: Improve tests for emplace member of sequence containers Our existing tests for std::deque::emplace, std::list::emplace and std::vector::emplace are poor. We only have compile tests for PR 52799 and the equivalent for a const_iterator as the insertion point. This fails to check that the value is actually inserted correctly and the right iterator is returned. Add new tests that cover the existing 52799.cc and const_iterator.cc compile-only tests, as well as verifying the effects are correct. libstdc++-v3/ChangeLog: * testsuite/23_containers/deque/modifiers/emplace/52799.cc: Removed. * testsuite/23_containers/deque/modifiers/emplace/const_iterator.cc: Removed. * testsuite/23_containers/list/modifiers/emplace/52799.cc: Removed. * testsuite/23_containers/list/modifiers/emplace/const_iterator.cc: Removed. * testsuite/23_containers/vector/modifiers/emplace/52799.cc: Removed. * testsuite/23_containers/vector/modifiers/emplace/const_iterator.cc: Removed. * testsuite/23_containers/deque/modifiers/emplace/1.cc: New test. * testsuite/23_containers/list/modifiers/emplace/1.cc: New test. * testsuite/23_containers/vector/modifiers/emplace/1.cc: New test. --- diff --git a/libstdc++-v3/testsuite/23_containers/deque/modifiers/emplace/1.cc b/libstdc++-v3/testsuite/23_containers/deque/modifiers/emplace/1.cc new file mode 100644 index 000000000000..c6b0318e5ea2 --- /dev/null +++ b/libstdc++-v3/testsuite/23_containers/deque/modifiers/emplace/1.cc @@ -0,0 +1,70 @@ +// { dg-do run { target c++11 } } + +#include +#include + +void +test01() +{ + std::deque c; + std::deque::iterator pos; + + // libstdc++/52799 + pos = c.emplace(c.begin()); + VERIFY( c.size() == 1 ); + VERIFY( c[0] == 0 ); + VERIFY( pos == c.begin() ); + pos = c.emplace(c.begin(), 2); + VERIFY( c.size() == 2 ); + VERIFY( c[0] == 2 ); + VERIFY( c[1] == 0 ); + VERIFY( pos == c.begin() ); + pos = c.emplace(c.end(), 3); + VERIFY( c.size() == 3 ); + VERIFY( c[0] == 2 ); + VERIFY( c[1] == 0 ); + VERIFY( c[2] == 3 ); + VERIFY( pos == --c.end() ); + + // const_iterator + pos = c.emplace(c.cbegin()); + VERIFY( c.size() == 4 ); + VERIFY( c[0] == 0 ); + VERIFY( c[1] == 2 ); + VERIFY( pos == c.cbegin() ); + pos = c.emplace(c.cbegin() + 2, 22); + VERIFY( c.size() == 5 ); + VERIFY( c[0] == 0 ); + VERIFY( c[1] == 2 ); + VERIFY( c[2] == 22 ); + VERIFY( pos == c.cbegin() + 2 ); +} + +struct V +{ + explicit V(int a, int b = 0) : val(a+b) { } + int val; +}; + +void +test02() +{ + std::deque c; + std::deque::iterator pos; + + pos = c.emplace(c.end(), 1); + VERIFY( c.size() == 1 ); + VERIFY( c[0].val == 1 ); + VERIFY( pos == --c.end() ); + pos = c.emplace(c.cend(), 2, 3); + VERIFY( c.size() == 2 ); + VERIFY( c[0].val == 1 ); + VERIFY( c[1].val == 5 ); + VERIFY( pos == --c.cend() ); +} + +int main() +{ + test01(); + test02(); +} diff --git a/libstdc++-v3/testsuite/23_containers/deque/modifiers/emplace/52799.cc b/libstdc++-v3/testsuite/23_containers/deque/modifiers/emplace/52799.cc deleted file mode 100644 index 0beebb58248d..000000000000 --- a/libstdc++-v3/testsuite/23_containers/deque/modifiers/emplace/52799.cc +++ /dev/null @@ -1,27 +0,0 @@ -// { dg-do compile { target c++11 } } - -// Copyright (C) 2012-2023 Free Software Foundation, Inc. -// -// This file is part of the GNU ISO C++ Library.
