3;; Date:     May 28, 2003.
4;; From:     test/Programs/External/SPEC/CINT2000/175.vpr.llvm.bc
5;; Function: int %main(int %argc.1, sbyte** %argv.1)
6;;
7;; Error:    A function call with about 56 arguments causes an assertion failure
8;;           in llc because the register allocator cannot find a register
9;;           not used explicitly by the call instruction.
10;;
11;; Cause:    Regalloc was not keeping track of free registers correctly.
12;;           It was counting the registers allocated to all outgoing arguments,
13;;           even though most of those are copied to the stack (so those
14;;           registers are not actually used by the call instruction).
15;;
16;; Fixed:    By rewriting selection and allocation so that selection explicitly
17;;           inserts all copy operations required for passing arguments and
18;;           for the return value of a call, copying to/from registers
19;;           and/or to stack locations as needed.
