+Subject: [PATCH 01/17] basic_string::reserve(n) semantics are not available in
+ DTS
+
+Various tests were added upstream 2020-08-06 as part of:
+  "libstdc++: Implement P0966 std::string::reserve should not shrink"
+  https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=140cf935cd118f7208b7c3826a8b9d50936242f0
+
+std::string and std::wstring are instantiated in the system libstdc++.so
+via explicit instantiation definitions, so the new basic_string::reserve(n)
+semantics are not available in DTS.
+
+Update/disable the pertinent parts of the tests to reflect the behavior
+when run against the system libstdc++.so.

+
+The upstream commit on 2020-08--6:
+  Do not set eofbit eagerly in operator>>(istream&, char(&)[N])
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=4e39f563c0cd25401f689c2093cb8c13692156ef
+altered the behaviour of std::istream symbols defined in libstdc++.so,
+but with DTS you get the old definitions from the system libstdc++.so
+
+Hence this patch tweaks the new tests to avoid failing when run against
+the system libstdc++.so

+
+Upstream commit 2017-08-09
+  PR libstdc++/81751 don't call fflush(NULL)
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=04d07b61cb80fd97e98eb39451ff6a8675a63d90
+added these test cases as part of verifying the behavior of sys_open (that
+it resets errno and doesn't call fflush on NULL).
+
+These symbols are in the system stdlib when run from DTS and thus aren't
+fixed by the above change:
+
+ 1521: 000000000007c430    104 FUNC    GLOBAL DEFAULT       12 std::__basic_file<char>::sys_open(int, std::_Ios_Openmode)@@GLIBCXX_3.4

+
+This patch disables the non-fixed assertions.

+Looks like plugin.exp is building the test plugins against the
+freshly-built libstdc++, and then trying to dynamically load them
+against the system libstdc++.
+
+This patch forces the use of -std=c++11 when building these test plugins,
+to sidestep the problem.

+Subject: [PATCH 09/17] Fix 22_locale/locale/cons/unicode.cc when run under DTS
+
+Various has_facet calls return false in DTS, as DTS is using the
+std::locale from the system libstdc++.
+
+Hence this patch tweaks tests to remove the VERIFY from the result of
+the call, so that they do not fail if run against an older
+std::locale.
+
+These VERIFY tests were added upstream 2015-01-16 in
+  https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=bb93f35da1612940266f5d159b6cc5a3e54fca14

+Subject: [PATCH 11/17] Add dts.exp and use it to fix
+ 22_locale/messages/13631.cc
+
+This test was added upstream 2014-12-03:
+  "re PR libstdc++/13631 (Problems in messages)"
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=d31008d7a0d53b431f176aad8dda5498de823122
+
+as part of a fix that is present in the system libstdc++.so in
+GCC 5 onwards.
+
+When run in DTS against such a system library, this test will fail.
+This patch introduces a dts.exp which detects the version of the
+underlying system libstdc++.so and exposes it to tests via
+-D__CXXSTDLIB_SO_VERSION__=, so that we can ifdef specific tests
+away, conditionally on the base GCC.
