+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)

+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.

+
+Various testsuite plugins fail when built within DTS with e.g.:
+  cc1: error: cannot load plugin ./diagnostic_plugin_test_paths.so: /builddir/build/BUILD/gcc-11.1.1-20210623/obj-x86_64-redhat-linux/x86_64-redhat-linux/libstdc++-v3/src/.libs/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ./diagnostic_plugin_test_paths.so)
+
+These turn out to C++14's sized deletion
+(see https://en.cppreference.com/w/cpp/memory/new/operator_delete):
+
+   14: 0000000000000000      0 FUNC    GLOBAL DEFAULT    UNDEF _ZdlPvm@CXXABI_1.3.9 (4)

+
+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++.
+

+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

+ 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.

+Subject: [PATCH 16/17] Conditionalize test for hashtable bucket sizes on

+
+These tests were added upstream 2020-01-20 as part of:
+  libstdc++: Do not over-size hashtable buckets on range insertion
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=6dcf042368012e2d7ce1626ee5d378bf3ad0ccfc
+
+but fail when run in DTS against a system libstdc++.so from an older GCC.
+
+In particular, _M_insert_unique_node from the header is using the older
+implementation of
+  std::__detail::_Prime_rehash_policy::_M_need_rehash
+from the dynamic library.

+From 786869fd62813e80da9b6545a295d53c36275c19 Mon Sep 17 00:00:00 2001
+From: Mark Eggleston <markeggleston@gcc.gnu.org>
+Date: Fri, 22 Jan 2021 13:12:14 +0000
+Subject: [PATCH 06/10] Allow string length and kind to be specified on a per
+ variable basis.
+
+This allows kind/length to be mixed with array specification in
+declarations.
+
+e.g.
+
+      INTEGER*4 x*2, y*8
+      CHARACTER names*20(10)
+      REAL v(100)*8, vv*4(50)
+
+The per-variable size overrides the kind or length specified for the type.
+
+Use -fdec-override-kind to enable. Also enabled by -fdec.
+
+Note: this feature is a merger of two previously separate features.
+
+Now accepts named constants as kind parameters:
+
+      INTEGER A
+      PARAMETER (A=2)
+      INTEGER B*(A)
+
+Contributed by Mark Eggleston <mark.eggleston@codethink.com>
+
+Now rejects invalid kind parameters and prints error messages:
+
+      INTEGER X*3
+
+caused an internal compiler error.

+Subject: [PATCH 02/10] Convert LOGICAL to INTEGER for arithmetic ops, and vice
+ versa
+
+We allow converting LOGICAL types to INTEGER when doing arithmetic
+operations, and converting INTEGER types to LOGICAL for use in
+boolean operations.
+
+This feature is enabled with the -flogical-as-integer flag.
+
+Note: using this feature will disable bitwise logical operations enabled by
+-fdec.
