1 ; RUN: llc < %s 2 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. 20 ;; 21 %struct..s_annealing_sched = type { i32, float, float, float, float } 22 %struct..s_chan = type { i32, float, float, float, float } 23 %struct..s_det_routing_arch = type { i32, float, float, float, i32, i32, i16, i16, i16, float, float } 24 %struct..s_placer_opts = type { i32, float, i32, i32, i8*, i32, i32 } 25 %struct..s_router_opts = type { float, float, float, float, float, i32, i32, i32, i32 } 26 %struct..s_segment_inf = type { float, i32, i16, i16, float, float, i32, float, float } 27 %struct..s_switch_inf = type { i32, float, float, float, float } 28 29 define i32 @main(i32 %argc.1, i8** %argv.1) { 30 entry: 31 %net_file = alloca [300 x i8] ;
