Hi, folks, I'm trying to eliminate calls to classic string functions (strcpy, strcat, etc.) and memcpy from a shared library, built from C and C++ code with GCC 11.2. With -D_FORTIFY=2 and a bit of work with macros, I've eliminated all of them from the source, but I still have calls to memcpy from the object files. My suspected causes of these are: a) Struct copying, with memcpy calls inserted by the compiler. b) memcpy calls in the C++ Standard Template Library. Is there a way to ask GCC to use __builtin___memcpy_chk() in place of plain memcpy() for either of these? With best regards, -- John Dallman
