;; 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. ;; target endian = little target pointersize = 32 %struct..s_annealing_sched = type { uint, float, float, float, float }
