1 ; RUN: llc < %s
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.
