An granularity atom (in TCC's libraries) is one object file. If you compile two (or more) 
functions to the one object file, put the object file to a library and you use in your 
program only one of this function (from the library) - both functions will be included to 
your target binary. You must do very small pieces of code, several sources that was 
divided to atoms: functions, variables, etc. And you, of course, can use my tool 
"smartlinkrel" for dividing sources to atoms self-automatically, to be compiled 
to different object files and after this you can include they to the libraries.

If you are interested in the tool 'smartlinkrel', you can read more:

And you can see here an example of using of the tool 'smartlinkrel':

The tool is freeware. Written in Delphi and KOL (Key Object Library - 
http://www.kolmck.net/ ).
Sources are open and attached there. If you've questions and/or propositions 
about the 'smartlinkrel', e-mail me.
