Greetings, I try to find out why a function (inline keyword, defined in header) is not inlined. Example for -fdump-ipa-inline output: Considering void Vertex::update(const Data&)/5927 with 40 size to be inlined into void SomeClass::updatePoly(const Data&, Polyline&)/11181 in /somepath/SomeClass.cpp:663 Estimated badness is -0.000083, frequency 4.69. The function is never inlined. unfortunately, the code is proprietary, so I cannot post everything. Can anyone explain me the message above to find out why? Thanks
