Ok, so why do I get a "error: unrecognizable insn:"? How can I debug a
message like this:

(insn 12 11 13 2 (set (reg:CCFP 126)
         (compare:CCFP (reg:TF 123)
             (reg:TF 124))) "test-v0.i":5 -1
      (nil))
This is supposed to be matched by the cmptf_internal1 pattern with
-mabi=ibmlongdouble.  Looks like your configuration defaults to
-mabi=ieeelongdouble.

Yes, originally I tried to enable the 128-bit IEEE float support. I use now the default settings.
