Series sim, sim/ARCH: Add ATTRIBUTE_PRINTF |

Commit Message

  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.


	* m68hc11/m68hc11_sim.c (sim_memory_error): Add ATTRIBUTE_PRINTF.
	* m68hc11/sim-main.h (sim_memory_error): Likewise.
