Backend insn recog

[Hendrik Greving <hendrik.greving.intel@xxxxxxxxx>]

Hi, asking bluntly, what does it mean if I am running into

recog.c:extract_insn:fatal_insn_not_found (insn);

? Does this mean that there are some constraints that don't satisfy
something that the predicates allowed?

Thanks,
Regards,
