  I have a question regarding identifying symbols and thanks in advance for
your help.


    I pass an executable file as an argument to a simulator[SimpleScalar]
    which runs it instruction by instruction. When an event
    happens(eg. cache miss), I want to know which function of the original
    c code (i;e my program) is being executed at that point (binding an
adress to a symbol ?)
    there is a symbol table and also an interface to bind address to a
    symbol but the problem is the address is being bound to a kernel
  function(for eg. __do_global..) and not the function in my benchmark.


    Is there anyway in which I can get the name of my function at this point
    ? - also, can someone give me a neat pointer to symbol table
construction - i'm not sure if every kernel symbol required by the program
is stored in sym tab - i want to know what exactly goes in constructing a
  symtab.
  Thanks alot for your help
