;; Date: May 27, 2003.
;; From: test/Programs/MultiSource/McCat-05-eks/QRfact.c
;; Function: Matrix QRiterate(Matrix A, Matrix U)
;;
;; Error: llc produces an invalid register <NULL VALUE> for the
;; a boolean value computed using setne with a double.
;;
;; Cause: In SparcInstrSelection.cpp, for SetCC, when a result of setne
;; is used for a branch, it can generate a "branch-on-integer-register"
;; for integer registers. In that case, it never saves the value of
;; the boolean result. It was attempting to do the same thing for an
;; FP compare!
