From 716e54731f30bc60b2fc52996ebe4fc087420b2e Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Tue, 3 May 2022 23:17:31 +0000 Subject: gdb: Workaround stringop-overread warning in debuginfod-support.c on s390x For some reason g++ 11.2.1 on s390x produces a spurious warning for stringop-overread in debuginfod_is_enabled for url_view. Add a new DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD macro to suppress this warning. include/ChangeLog: * diagnostics.h (DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD): New macro. gdb/ChangeLog: * debuginfod-support.c (debuginfod_is_enabled): Use DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD on s390x. --- include/diagnostics.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'include/diagnostics.h') diff --git a/include/diagnostics.h b/include/diagnostics.h index f10d066..8bf5a3c 100644 --- a/include/diagnostics.h +++ b/include/diagnostics.h @@ -76,6 +76,9 @@ # define DIAGNOSTIC_IGNORE_STRINGOP_TRUNCATION \ DIAGNOSTIC_IGNORE ("-Wstringop-truncation") +# define DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD \ + DIAGNOSTIC_IGNORE ("-Wstringop-overread") + # define DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL \ DIAGNOSTIC_IGNORE ("-Wformat-nonliteral") @@ -108,6 +111,10 @@ # define DIAGNOSTIC_IGNORE_STRINGOP_TRUNCATION #endif +#ifndef DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD +# define DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD +#endif + #ifndef DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL # define DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL #endif -- cgit v1.1
