Detailed Description
A Symbol that holds equate information for a constant.
This is a symbol that labels a constant. It can either replace the constant's token with the symbol name, or it can force a conversion in the emitted format of the constant.
Member Function Documentation
◆ isValueClose()
| bool EquateSymbol::isValueClose | ( | uintb | op2Value, |
| int4 | size | ||
| ) | const |
Is the given value similar to this equate.
An EquateSymbol should survive certain kinds of transforms during decompilation, such as negation, twos-complementing, adding or subtracting 1. Return true if the given value looks like a transform of this type relative to the underlying value of this equate.
- Parameters
-
op2Value is the given value size is the number of bytes of precision
- Returns
- true if it is a transformed form
