I have a question regarding the C++ compiler.
When exactly the C++ compiler will create a common symbol? With a C compiler I could provide common symbols to the object file, but if I compile the very same code with a C++ compiler (GNU), I only get only defined and undefined symbols.
So the question is what circumstances will cause a variable/function to be compiled as common in C++?
Some of them never do. The late and much-lamented Watcom C++ compiler made great use of common symbols to economize on inline function instances. There are various cases of
externthat can also be resolved economically in this way.
