There is one "fcmp;fblt" and three "fcmp;fbne" sequences in the previously failing test case (just the .o file, so excluding libgmp.a). There are 24 fcmps in libgmp.a, but they are all followed by relational conditional jumps, none is followed by an equality/inequality conditional jump. Should I close this as a duplicate of PR323?
