--- Comment #92 from Alexander Klepikov <klepikov.alex+bugs at gmail dot com> --- I remembered why I used two different insns - first to eliminate infinite loop with help of marking insn with attribute, and second because I could not set attribute when emitting insn from C code. Whe have 'get_attr_*' functions but we have not 'set_attr_*'.
