Assembly generation chnages between compiler versions

Ok. I do see some changes in the end of function marker in the assembly
output, between 2.95 and 3.4 compiler. The 2.95 compiler was using .Lef
whereas 3.4 will use .-<function name>. Why this has been changed, do you
have any pointer which says about the major changes from 2.95 to 3.4 GCC
compiler .

Thanks 
Sharath.
