Detailed Description
This is an important base class in LLVM.
It provides the common facilities of all constant values in an LLVM program. A constant is a value that is immutable at runtime. Functions are constants because their address is immutable. Same with global variables.
All constants share the capabilities provided in this class. All constants can have a null value. They can have an operand list. Constants can be simple (integer and floating point values), complex (arrays and structures), or expression based (computations yielding a constant value composed of only certain operators and other constant values).
Note that Constants are immutable (once created they never change) and are fully shared by structural equivalence. This means that two structurally equivalent constants will always have the same address. Constants are created on demand as needed and never deleted: thus clients don't have to worry about the lifetime of the objects. LLVM Constant Representation

◆ canTrap()
| bool Constant::canTrap | ( | ) | const |
Return true if evaluation of this constant could trap.
This is true for things like constant expressions that could divide by zero.

Return true if this is a vector constant that includes any poison elements.
Definition at line 333 of file Constants.cpp.
References containsUndefinedElement().
Referenced by llvm::ConstantFoldSelectInstruction().
◆ containsUndefOrPoisonElement()
| bool Constant::containsUndefOrPoisonElement | ( | ) | const |
Return true if this is a vector constant that includes any undef or poison elements.
Since it is impossible to inspect a scalable vector element- wise at compile time, this function returns true only if the entire vector is undef or poison.
Definition at line 328 of file Constants.cpp.
References containsUndefinedElement().
◆ destroyConstant()
| void Constant::destroyConstant | ( | ) |
Called if some element of this constant is no longer valid.
At this point only other constants may be on the use_list for this constant. Any constants on our Use list must also be destroy'd. The implementation must be sure to remove the constant from the list of available cached constants. Implementations should implement destroyConstantImpl to remove constants from any pools/maps they are contained it.
First call destroyConstantImpl on the subclass. This gives the subclass a chance to remove the constant from any maps/pools it's contained in.

◆ getAggregateElement() [2/2]
| Constant * Constant::getAggregateElement | ( | unsigned | Elt | ) | const |
For aggregates (struct/array/vector) return the constant that corresponds to the specified element if possible, or null if not.
This can return null if the element index is a ConstantExpr, if 'this' is a constant expr or if the constant does not fit into an uint64_t.

If all elements of the vector constant have the same value, return that value.
Otherwise, return nullptr. Ignore undefined elements by setting AllowUndefs to true.

◆ handleOperandChange()
This method is a special form of User::replaceUsesOfWith (which does not work on constants) that does work on constants.
Update this constant array to change uses of 'From' to be uses of 'To'.
Basically this method goes through the trouble of building a new constant that is equivalent to the current one, with all uses of From replaced with uses of To. After this construction is completed, all of the users of 'this' are replaced to use the new constant, and then 'this' is deleted. In general, you should not call this method, instead, use Value::replaceAllUsesWith, which automatically dispatches to this method as needed.
This must update the uniquing data structures etc.
Note that we intentionally replace all uses of From with To here. Consider a large array that uses 'From' 1000 times. By handling this case all here, ConstantArray::handleOperandChange is only invoked once, and that single invocation handles all 1000 uses. Handling them one at a time would work, but would be really slow because it would have to unique each updated array instance.
