Pointers to these functions are used in comparisons. Currently the compiler has to presume the worst for these, namely that the functions are from another DSO and therefore loads their addresses from the GOT (which also entails a relocation entry that is processed at runtime, regardless of whether the code using them is run or not). This changes after these functions are declared as hidden. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
