forked from BigfootDev/flatbuffers
f7c511957f
Added (for compiler versions that support it): -Wmissing-declarations -Wzero-as-null-pointer-constant Then, fixes to problems identified by the extra warnings Tested only on GCC 9.4.0 Adjusted the CPP code generator to output nullptr where appropriate, to satisfy -Wzero-as-null-pointer-constant Added a lot of 'static' declarations in front of functions, to satisfy -Wmissing-declarations, and wrap static function defs in anonymous namespaces. There are advantages to both anonymous namespaces and static, it seems that marking a function as static will not publish the name in the symbol table at all, thus giving the linker less work to do.
