I've been using a technique like this in some code with good results:
struct source_location
{
const char *file;
const char *func;
const char *format;
uint16_t line;
};
#define _LOCATION(format) ({static const source_location __location__ = {\
__FILE__,__PRETTY_FUNCTION__,format,__LINE__};\
&__location__;})
void _mlx5_core_err(const struct source_location *loc,struct mlx5_core_dev *dev, ...);
#define mlx5_core_err(dev,format,...) _mlx_core_err(_LOCATION(format),dev,__VA_ARGS__)
The call site .text overhead is the about same as what you have, but
this still retains the function and line number information in
.rodata.
