On the default configuration, it causes a build failure (unless "--disable-werror" is specified). However, non-literal format string is completely safe here. We have "include/diagnostics.h" to suppress certain warnings only when necessary. Because DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL can suppress warnings when the format string of a printf-like function is not a literal, this commit adds this macro (only where necessary) to suppress this warning. sim/ChangeLog: * common/sim-hw.c (hw_vabort): Suppress non-literal printf warning by using DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL. --- sim/common/sim-hw.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/sim/common/sim-hw.c b/sim/common/sim-hw.c index cece5638bc9..36f355d2262 100644 --- a/sim/common/sim-hw.c +++ b/sim/common/sim-hw.c @@ -425,10 +425,13 @@ hw_vabort (struct hw *me, strcat (msg, ": "); strcat (msg, fmt); /* report the problem */ + DIAGNOSTIC_PUSH + DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL sim_engine_vabort (hw_system (me), STATE_HW (hw_system (me))->cpu, STATE_HW (hw_system (me))->cia, msg, ap); + DIAGNOSTIC_POP } void -- 2.34.1
