Detailed Description

ExprReduce example.
This example retrieve the nature of a given expression
Input:
ECX is a pointer on a structure STRUCT_A

Reduction rules:
ECX              -> FIELD_A_PTR
ECX + CST        -> FIELD_A_PTR
ECX + CST*CST... -> FIELD_A_PTR
@ECX             -> FIELD_A
@(ECX + CST)     -> FIELD_A
