Actally, there is. It uses the assembler to generate a listing file:

gcc -c -g -O2 -Wa,-alh foo.c>foo.lst

or

gcc -c -g -O2 -Wa,-alh foo.cc>foo.lst

The -O2 isn't needed, it's just to show that this still works with 
optimisation. One word of warnig: C++ puts line number info for 
generated functions as well as your functions, causing some strange 
results, but your functions will have the correct lines associated 
with them (there just may be more one line 50 from the debug info's 
point of view).
