Expand description
See LLVM 12 docs on Constants. Constants can be either values, or expressions involving other constants (see LLVM 12 docs on Constant Expressions).

Show fields
Fields of Int
bits: u32
Number of bits in the constant integer
value: u64
The constant value itself.
If bits == 64
, this is the value.
If bits < 64
, the constant value is zero-extended to fit in this
field.
If bits > 64
, the constant value is truncated to fit in this field;
but if this truncation would change the value (i.e., if the value is
>= 2^64 when interpreted as unsigned) then Module::from_bc_path()
will fail. See #5.
Float(Float)
Null(TypeRef)
The TypeRef
here must be to a PointerType
. See LLVM 12 docs on Simple Constants
AggregateZero(TypeRef)
A zero-initialized array or struct (or scalar).

Fields of Array
element_type: TypeRef
elements: Vec<ConstantRef>
Vector(Vec<ConstantRef>)
Undef(TypeRef)
Undef
can be used anywhere a constant is expected. See LLVM 12 docs on Undefined Values
The address of the given (non-entry) BasicBlock
. See LLVM 12 docs on Addresses of Basic Blocks.
BlockAddress
needs more fields, but the necessary getter functions are apparently not exposed in the LLVM C API (only the C++ API)
