You can use __builtin_return_address if you were using gcc to get to the
address of the calling function . Getting to the name is a simple matter
of using a script to identify the function in which the address is
located, you can use an intelligent script using objdump / readelf to
get to it. Ofcourse you'll have to do some more hackery if this were in
a shared library :) .
