[4/7] sim/m32c: 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 the printf-like functions.
sim/ChangeLog:
* m32c/trace.c (op_printf, op_styled_printf): Add
ATTRIBUTE_PRINTF.
