It caused a compiler error when... - Compiled with Clang - -Werror is specified (by default) - C++ standard used by Clang is before C++17 (by default as of 15.0.0) when this unit test is activated. This issue is raised as PR28413. However, previous proposal to fix this issue (a "fix" to Gnulib): was rejected because it ruins the intent of Gnulib warnings. So, we need a Binutils/GDB-side solution. This commit tries to address this issue on the GDB side. We have "include/diagnostics.h" to disable certain warnings only when necessary. This commit suppresses the Gnulib warnings by surrounding entire #include block with DIAGNOSTIC_IGNORE_USER_DEFINED_WARNINGS to disable Gnulib- generated warnings on all standard C++ header files. --- gdb/unittests/string_view-selftests.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/gdb/unittests/string_view-selftests.c b/gdb/unittests/string_view-selftests.c index 2d7261d18d3..441d533b54e 100644 --- a/gdb/unittests/string_view-selftests.c +++ b/gdb/unittests/string_view-selftests.c @@ -23,6 +23,11 @@ #define GNULIB_NAMESPACE gnulib +#include "diagnostics.h" + +DIAGNOSTIC_PUSH +DIAGNOSTIC_IGNORE_USER_DEFINED_WARNINGS + #include "defs.h" #include "gdbsupport/selftest.h" #include "gdbsupport/gdb_string_view.h" @@ -34,6 +39,8 @@ #include #include +DIAGNOSTIC_POP + /* libstdc++'s testsuite uses VERIFY. */ #define VERIFY SELF_CHECK -- 2.34.1
