--- Comment #27 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Now, perhaps the analysis code could also detect which lhs are directly or
indirectly needed by debug stmts and when doing this return NULL in
remap_gimple_stmt, we could do something like (much simplified)
insert_debug_temp_for_var_def in there.  Though unsure if we must always handle
first the SSA_NAME definitions before uses, if not, then we'd need to figure
out the SSA_NAME to DEBUG_EXPR_DECL mapping early and then just let
remap_gimple_stmt add the debug stmt for it.
Perhaps ignore debug stmts for now as long as it doesn't ICE on them and I'll
try to do something for those?
