◆ dumpOS()

void llvm::sandboxir::ConstantInt::dumpOS ( raw_ostream & OS) const	inlineoverridevirtual

◆ equalsInt()

bool llvm::sandboxir::ConstantInt::equalsInt ( uint64_t V) const	inline

A helper method that can be used to determine if the constant contained within is equal to a constant.

This only works for very small values, because this is all that can be represented with all types. Determine if this constant's value is same as an unsigned char.

◆ get() [1/5]

◆ get() [2/5]

◆ get() [3/5]

Return a ConstantInt with the specified integer value for the specified type.

If the type is wider than 64 bits, the value will be zero-extended to fit the type, unless IsSigned is true, in which case the value will be interpreted as a 64-bit signed integer and sign-extended to fit the type. Get a ConstantInt for a specific value.

uint64_t llvm::sandboxir::ConstantInt::getLimitedValue ( uint64_t Limit = ~0ULL) const	inline

getLimitedValue - If the value is smaller than the specified limit, return it, otherwise return the limit value.

This causes the value to saturate to the limit.

Returns

the min of the value of the constant and the specified value Get the constant's value with a saturation limit

◆ isValueValidForType() [1/2]

bool llvm::sandboxir::ConstantInt::isValueValidForType ( Type * Ty, int64_t V )	static

◆ isValueValidForType() [2/2]

bool llvm::sandboxir::ConstantInt::isValueValidForType ( Type * Ty, uint64_t V )	static

This static method returns true if the type Ty is big enough to represent the value V.

This can be used to avoid having the get method assert when V is larger than Ty can represent. Note that there are two versions of this method, one for unsigned and one for signed integers. Although ConstantInt canonicalizes everything to an unsigned integer, the signed version avoids callers having to convert a signed quantity to the appropriate unsigned type before calling the method.

Returns

true if V is a valid value for type Ty Determine if the value is in range for the given type.

◆ uge()

bool llvm::sandboxir::ConstantInt::uge ( uint64_t Num) const	inline

This function will return true iff this constant represents a value with active bits bigger than 64 bits or a value greater than the given uint64_t value.

Returns

true iff this constant is greater or equal to the given number. Determine if the value is greater or equal to the given number.
