readelf.c: Avoid repeating calls to gettext _() in hotpathupstream/users/amerey/try-readelf-concurrency
Calls to the gettext _() macro in hotpaths cause many runtime lookups of the same translation strings. This patch introduces macro __() which caches the result of _() at each call site where __() is used. When a cached translation string is used as the format string for fprintf, the compiler might raise a -Wformat-nonliteral warning. To avoid this, the -Wformat-nonliteral warning is suppressed using _Pragma around affected fprintf calls, using IGNORE_FMT_NONLITERAL_BEGIN and _END wrappers. To avoid suppressing -Wformat-nonliteral across every printf-style function using _(), __() and IGNORE_FMT_NONLITERAL_* are mostly used within hotpath loops where caching makes a signficant difference. Runtime improvements of up to 13% faster have been observed with this patch applied. Signed-off-by: Aaron Merey <[email protected]>
