;; 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 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.
