OS X build regularly reports some 39 warnings falling in 3 major categories: * "static function '...' is used in an inline function with external linkage [-Wstatic-in-inline]": Some semantics around `inline` have changed between C89 and C99, and gcc and clang seem to disagree on how strict they should be about them. Solution chosen is to use `-Wnostatic-in-inline` command line option for clang. * "implicit conversion turns floating-point number into integer: 'double' to 'bool' [-Wfloat-conversion]": `if (fmod (..., ...))` was used at different places, which is not nice anyway, thus the return value is compared explicitly against `ECMA_NUMBER_ZERO`. * "format string is not a string literal [-Wformat-nonliteral]": Console and log port I/O functions have a printf-like interface, and the default implementations actually pass both format string and the remaining arguments to a vfprintf. However, clang is strict about the format string parameter of vfprintf and expects a literal there. By annotating the port I/O functions with `__attribute__ ((format (printf, ..., ...)))`, clang will check the format string being a literal string earlier, when the port functions are called, and will not complain within them when vfprintf is called. (Actually, this has revealed an incorrect format string, which has been fixed as well.) (There were also some single conversion errors not listed above.) The patch was tested on OS X (where all warnings disappeared), but it should help clang compilation on other OS's as well. JerryScript-DCO-1.0-Signed-off-by: Akos Kiss akiss@inf.u-szeged.hu
