The OP doesn't want an address at all. Inside function1, he wants to do something and get either "function2" or "main" as the result, depending on which of those called him. This might mean obtaining the the returm address as an intermediate result and then scanning a symbol table, but the address is not the objective. This would only be doable if the program was compiled with symbolic debugging information included as for use with a symbolic debugger like gdb. I'm not going to try something that daunting for such a minor result.

If I really needed that, I would expand the argument list of the function1 module to contain a field called "caller". Then I use:
function1("main")
function1("function2")
as needed. function1 would refer to the first argument to find the caller.

evolvotron_mutate

EVOLVOTRON_MUTATE(1)						    Evolvotron						      EVOLVOTRON_MUTATE(1)

NAME

       evolvotron_mutate - Render an evolvotron function tree to an image.

SYNOPSIS

       evolvotron_mutate < function_in.xml > function_out.xml

       evolvotron_mutate -g > function_out.xml

DESCRIPTION

       evolvotron_mutate either mutates an existing image function (saved to an XML file), or (with the -g option) creates a new image function.

       The mutation parameters and function weightings are the same as used by evolvotron in its default reset state.

       See the evolvotron user manual (accessible from the evolvotron application's Help menu) for more information on image functions.

COMMANDLINE OPTIONS

       -g   Specifies that no function should be read from standard input.  The output function is created at random.

EXAMPLES

       evolvotron_mutate -g | tee function0.xml | evolvotron_render function0.ppm

       evolvtron_mutate < function0.xml > function1.xml
