; RUN: llc < %s

;; Date:     May 28, 2003.
;; From:     test/Programs/External/SPEC/CINT2000/175.vpr.llvm.bc
;; Function: int %main(int %argc.1, sbyte** %argv.1)
;;
;; Error:    A function call with about 56 arguments causes an assertion failure
;;           in llc because the register allocator cannot find a register
;;           not used explicitly by the call instruction.
;;
;; Cause:    Regalloc was not keeping track of free registers correctly.
;;           It was counting the registers allocated to all outgoing arguments,
;;           even though most of those are copied to the stack (so those
;;           registers are not actually used by the call instruction).
;;
;; Fixed:    By rewriting selection and allocation so that selection explicitly
;;           inserts all copy operations required for passing arguments and
;;           for the return value of a call, copying to/from registers
;;           and/or to stack locations as needed.
