Description

Pcard-67164
Add Div to replace Recipical in DimExpr

添加关于 Div 的化简

  1. Div(S0, 1) => S0, Div(0, S0) => 0
  2. 分子分母的约分
  • Div(Mul(S1, S2, S3), S1) => Mul(S1, S2)
  • Div(Mul(S1, 8), 6) => Div(Mul(S1, 4), 3)

Mul 的常量折叠不再考虑分式结构，删除分式结构

删除原本 Mul(S0, Reciprocal(S0)) 的消除

TODO

  • 优化 SimplifyDiv 中重复代码
