Public Methods
public abstract IEImm _sar (int cnt)
Perform an arithmetic right-shift operation (sign bit is maintained).
public abstract int _signum ()
public abstract boolean _testbit (int pos)
Test if a given bit is set.
Returns
- true if set, false if unset
public abstract boolean canReadAsAddress ()
public abstract boolean canReadAsLong ()
public abstract boolean canReadAsUnsignedLong ()
public abstract IEImm expand (int bits)
Expand (zero-extension) this immediate. If bits if less than the bitsize of this immediate, this method is the same as truncate. If bits is greater than the bitsize of this immediate, then the resulting value is zero-extended.
public abstract BigInteger getUnsignedValue ()
Get this immediate as an unsigned big integer value.
public abstract BigInteger getValue ()
Get this immediate as a big integer value (signed).
public abstract long getValueAsAddress ()
Get the immediate value as a primitive long, preferably unsigned. Will raise if the value does not fit on 64-bits.
public abstract long getValueAsLong ()
Get the immediate value as a signed primitive long. Will raise if the value does not fit in [LONG_MIN, LONG_MAX] range (64 bits).
public abstract long getValueAsUnsignedLong ()
Get the immediate value as an unsigned, zero-extended primitive long. Will raise if the value does not fit within [0, LONG_MAX] range (63 bits).
getValueAsLong() is a safer method.
public abstract IEGeneric signExtend (int newBitsize)
Sign extend the current IEGeneric. This method will create a valid IEGeneric
(meaning IEGeneric will not have duplicates id - in particular, in the form C(x,
x.msb()?ones():zeros()) where x will be present in base value and msb predicate)
Parameters
| newBitsize | must be superior to getBitsize()
|
|---|
public abstract IEImm truncate (int bits)
Truncate this immediate or sign-extend it. If bits if less than the bitsize of this immediate, it is truncated. If bits is greater than the bitsize of this immediate, then the resulting value is sign-extended.
public abstract IEGeneric zeroExtend (int newBitsize)
Zero extend the current IEGeneric
Parameters
| newBitsize | must be superior to getBitsize()
|
|---|
