[PATCH PR90240][RFC]Avoid scaling cost overflow by introducing scaling bound

2019-04-26 Thread bin.cheng
Hi, This is the draft patch avoiding scaling cost overflow by introducing a scaling bound in IVOPTs. For now the bound is 20, and scaling factor will be further scaled wrto this bound. For example, scaling factor like 1, 1000, 2000(max) would be scaled to 1, 10, 20 correspondingly. HI Martin
