On the default configuration, it causes a build failure (unless "--disable-werror" is specified). To avoid warnings on the printf-like wrapper, it requires proper __attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason. This commit adds ATTRIBUTE_PRINTF to a printf-like function. sim/ChangeLog: * common/sim-cpu.h (sim_io_eprintf_cpu): Add ATTRIBUTE_PRINTF. --- sim/common/sim-cpu.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sim/common/sim-cpu.h b/sim/common/sim-cpu.h index d8b2b9c494a..024eb31d79a 100644 --- a/sim/common/sim-cpu.h +++ b/sim/common/sim-cpu.h @@ -137,7 +137,8 @@ extern sim_cpu *sim_cpu_lookup (SIM_DESC, const char *); /* Return prefix to use in cpu specific messages. */ extern const char *sim_cpu_msg_prefix (sim_cpu *); /* Cover fn to sim_io_eprintf. */ -extern void sim_io_eprintf_cpu (sim_cpu *, const char *, ...); +extern void sim_io_eprintf_cpu (sim_cpu *, const char *, ...) + ATTRIBUTE_PRINTF (2, 3); /* Get/set a pc value. */ #define CPU_PC_GET(cpu) ((* CPU_PC_FETCH (cpu)) (cpu))
