; 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.
