From 7aaf9c03d143802302c49ed70d05766c9cf3cb5b Mon Sep 17 00:00:00 2001 From: Tsukasa OI Date: Thu, 6 Oct 2022 06:36:27 +0000 Subject: sim/common: Add ATTRIBUTE_PRINTF Clang generates a warning if the format string of a printf-like function is not a literal ("-Wformat-nonliteral"). 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/common/sim-cpu.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'sim') diff --git a/sim/common/sim-cpu.h b/sim/common/sim-cpu.h index d8b2b9c..9e09a55 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)) -- cgit v1.1
