Types

LLVMType

Abstract supertype for all LLVM types.

issized(typ::LLVMType)

Return true if it makes sense to take the size of this type.

Note that this does not mean that it's possible to call sizeof on this type, as LLVM types sizes can only queried given a target data layout.

See also: sizeof(::DataLayout, ::LLVMType).

context(typ::LLVMType)

Returns the context in which the given type was created.

eltype(typ::LLVMType)

Get the element type of the given type, if supported.

LLVM.IntegerType <: LLVMType

Type representing arbitrary bit width integers.

LLVM.IntType(bits::Integer)

Create an integer type with the given bits width.

Short-hand constructors are available for common widths: LLVM.Int1Type, LLVM.Int8Type, LLVM.Int16Type, LLVM.Int32Type, LLVM.Int64Type, and LLVM.Int128Type.

width(inttyp::LLVM.IntegerType)

Get the bit width of the given integer type.

LLVM.HalfType()

Create a 16-bit floating-point type.

LLVM.BFloatType()

Create a 16-bit “brain” floating-point type.

LLVM.FloatType()

Create a 32-bit floating-point type.

LLVM.DoubleType()

Create a 64-bit floating-point type.

LLVM.FP128Type()

Create a 128-bit floating-point type, with a 113-bit significand.

LLVM.X86FP80Type()

Create a 80-bit, X87 floating-point type.

LLVM.PPCFP128Type()

Create a 128-bit floating-point type, consisting of two 64-bits.

LLVM.FunctionType <: LLVMType

A function type, representing a function signature.

isvararg(ft::LLVM.FunctionType)

Check whether the given function type is variadic.

return_type(ft::LLVM.FunctionType)

Get the return type of the given function type.

parameters(ft::LLVM.FunctionType)

Get the parameter types of the given function type.

LLVM.PointerType <: LLVMType

A pointer type.

addrspace(ptrtyp::LLVM.PointerType)

Get the address space of the given pointer type.

is_opaque(ptrtyp::LLVM.PointerType)

Check whether the given pointer type is opaque.

LLVM.ArrayType <: LLVMType

An array type, representing a fixed-size array of identically-typed elements.

length(arrtyp::LLVM.ArrayType)

Get the length of the given array type.

isempty(arrtyp::LLVM.ArrayType)

Check whether the given array type is empty.

LLVM.VectorType <: LLVMType

A vector type, representing a fixed-size vector of identically-typed elements. Typically used for SIMD operations.

length(vectyp::LLVM.VectorType)

Get the length of the given vector type.

LLVM.StructType <: LLVMType

A structure type, representing a collection of named fields of potentially different types.

name(structtyp::StructType)

Get the name of the given structure type.

ispacked(structtyp::LLVM.StructType)

Check whether the given structure type is packed.

isopaque(structtyp::LLVM.StructType)

Check whether the given structure type is opaque.

elements!(structtyp::LLVM.StructType, elems::LLVMType[]; packed=false)

Set the elements of the given structure type to elems. The packed argument indicates whether the structure should be packed, i.e., without padding between fields.

See also: elements.

elements(structtyp::LLVM.StructType)

Get the elements of the given structure type.

See also: elements!.

LLVM.VoidType <: LLVMType

A void type, representing the absence of a value.

LLVM.LabelType <: LLVMType

A label type, representing a code label.

LLVM.MetadataType <: LLVMType

A metadata type, representing a metadata value.

LLVM.TokenType <: LLVMType

A token type, representing a token value.

types(ctx::LLVM.Context)

Get a dictionary of all types in the given context.
