Speaking of which. It is indeed quite bad.
For one, saved_eip is only ever set to point to ret_point:
ENTRY(saved_eip) .long 0
...
movl $ret_point, saved_eip
and it has just a single user, where an indirect jump
through it is performed:
# jump to place where we left off
movl saved_eip, %eax
jmp *%eax
No comments why it is so.
All this seems to be equivalent to trivial
# jump to place where we left off
jmp ret_point
Am I missing something?
