|  | ;; 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. |
