+Subject: [PATCH 1/3] gcc-common.h: Update for GCC 10
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Remove "params.h" include, which has been dropped in GCC 10.
+
+Remove is_a_helper() macro, which is now defined in gimple.h, as seen
+when running './scripts/gcc-plugin.sh g++ g++ gcc':
+
+In file included from <stdin>:1:
+./gcc-plugins/gcc-common.h:852:13: error: redefinition of ‘static bool is_a_helper<T>::test(U*) [with U = const gimple; T = const ggoto*]’
+  852 | inline bool is_a_helper<const ggoto *>::test(const_gimple gs)
+      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~
+In file included from ./gcc-plugins/gcc-common.h:125,
+                 from <stdin>:1:
+/usr/lib/gcc/x86_64-redhat-linux/10/plugin/include/gimple.h:1037:1: note: ‘static bool is_a_helper<T>::test(U*) [with U = const gimple; T = const ggoto*]’ previously declared here
+ 1037 | is_a_helper <const ggoto *>::test (const gimple *gs)
+      | ^~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Add -Wno-format-diag to scripts/gcc-plugins/Makefile to avoid
+meaningless warnings from error() formats used by plugins:
+
+scripts/gcc-plugins/structleak_plugin.c: In function ‘int plugin_init(plugin_name_args*, plugin_gcc_version*)’:
+scripts/gcc-plugins/structleak_plugin.c:253:12: warning: unquoted sequence of 2 consecutive punctuation characters ‘'-’ in format [-Wformat-diag]
+  253 |   error(G_("unknown option '-fplugin-arg-%s-%s'"), plugin_name, argv[i].key);
+      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
