Is the C standard library embedded with the program ?

When i compile my project with gcc, does it :

• Include all the C standard library with my source code into the flash memory ?
• Or does it include only what i've used ?
• Or does it not include it at all ?

Thanks.

#c-compiler #c-library

Normally, the linker which comes with gcc links only those functions from the standard library, which are used by the program.
