Variants

Int

Fields of Int

bits: u32value: u64

Float(Float)

Null(Type)

The Type here must be a PointerType. See LLVM 9 docs on Simple Constants

AggregateZero(Type)

A zero-initialized array or struct (or scalar).

Struct

Fields of Struct

name: Option<String>values: Vec<Constant>is_packed: bool

Array

Fields of Array

element_type: Typeelements: Vec<Constant>

Vector(Vec<Constant>)

Undef(Type)

Undef can be used anywhere a constant is expected. See LLVM 9 docs on Undefined Values

BlockAddress

The address of the given (non-entry) BasicBlock. See LLVM 9 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)
