Hi Segher, How can I tell which insn is using the wrong mode, or which macro or function is using the wrong mode ? I have been debugging this for days, but I can't figure what is causing the infinite recursion. Could you please suggest what debugging method I could use to locate what is causing the infinite recursion ?
