Greetings,

In what precise way does %ebp "characterise" a stack frame? Does it point
to the first address on the current stack frame? If so shouldn't each
nested procedure call redefine %ebp to set up a new stack frame for its
use? 

I have looked at some .s files produced by gcc and all they do is push and 
pop %ebp at each procedure call. Where is it initialised if at all? I 
suspect that this is done in crt0.s but would be grateful for the range 
of line numbers in the relevant file where this is accomplished 


Many thanks in advance
