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 the printf-like functions.

sim/ChangeLog:

	* erc32/interf.c (fprintf_styled): Add ATTRIBUTE_PRINTF.
	* erc32/sis.c (fprintf_styled): Likewise.
