; 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. ;; %struct..s_annealing_sched = type { i32, float, float, float, float } %struct..s_chan = type { i32, float, float, float, float } %struct..s_det_routing_arch = type { i32, float, float, float, i32, i32, i16, i16, i16, float, float } %struct..s_placer_opts = type { i32, float, i32, i32, i8*, i32, i32 } %struct..s_router_opts = type { float, float, float, float, float, i32, i32, i32, i32 } %struct..s_segment_inf = type { float, i32, i16, i16, float, float, i32, float, float } %struct..s_switch_inf = type { i32, float, float, float, float } define i32 @main(i32 %argc.1, i8** %argv.1) { entry: %net_file = alloca [300 x i8] ;
