What is the address of this line?

[John Carter]

So we using gcc on an embedded platform. ie. Very constrained flash & ram.

We also using asserts.

Storing __LINE__ and __FILE__ is taking too much flash.

Question: I would like to create an assert macro ....

#define Assert( expression) do {\
   if(!(expression)) { \
     assert_occurred_at_program_counter = THE_ADDRESS_OF_THIS_LINE(); \
   }
} while(0)


So how do I write that magical function / macro
THE_ADDRESS_OF_THIS_LINE(); That returns the address / PC at that line?
Preferable in a CPU neutral fashion, otherwise for a Sparc CPU.
