------- Comment #2 from aoliva at gcc dot gnu dot org 2010-06-02 06:43 -------
My mid-term vision to address this sort of problem does not involve adding more
debug bind insns (I don't quite see how to get them right), but rather emit a
new kind of debug stmt/insn so as to emit is_stmt notes in lineno, so we can
set breakpoints at the right spot for line 19, rather than at the moved-ahead
insns, avoiding all the bouncing back-and-forth when stepping in optimized
programs. I ought to go ahead and implement this one of these days.
