rev 5188 : 8024344: PPC64 (part 112): C argument in register AND stack slot.
Summary: On PPC, the first 13 floating point arguments to C calls are passed in floating point registers. Also, all but the first 8 arguments are passed on the stack. So there can be floating point arguments that are passed on the stack and in a register. We duplicate the regs datastructure in c_calling_convention() to represent this.

*** 133,141 **** --- 133,142 ---- } int SharedRuntime::c_calling_convention(const BasicType *sig_bt, VMRegPair *regs, + VMRegPair *regs2, int total_args_passed) { ShouldNotCallThis(); return 0; }
