I am working on a problem to generate the execution profile of a
program, now that requires instrumenting the code with some profiling
func calls at appropriate positions.Here I am dealing with sun
executables(in ELF format). The question is how do I do the required
using the elf library routines.I have gone through the man pages and
elf_update seems to be the solution.But then I have not been able to
use it successfully.I would like any pointers to the use of elf_update
or rather generating an elf executable out of one.
