From 2f63213381e3b073f169ee776043486b44ea2e68 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Thu, 22 Apr 2021 12:07:14 -0400 Subject: sim: sprinkle some ATTRIBUTE_PRINTF Add some ATTRIBUTE_PRINTF attributes to functions that take a format string, to fix a few -Wformat-nonliteral warnings. Use the ATTRIBUTE_PRINTF macro like we use in GDB, instead of spelling out __attribute__((format...)). Use ATTRIBUTE_NULL_PRINTF at one place, because callers expect to be able to pass NULL. sim/common/ChangeLog: * callback.c (os_printf_filtered, os_vprintf_filtered, os_evprintf_filtered, os_error): Use ATTRIBUTE_PRINTF. * sim-engine.h (sim_engine_abort, sim_engine_vabort): Likewise. * sim-events.h (sim_events_schedule_tracef, sim_events_schedule_vtracef): Use ATTRIBUTE_NULL_PRINTF.
