Metadata

LLVM.MDString — Method
MDString(val::String)

Create a new string metadata node from the given Julia string.

source
Base.convert — Method
convert(String, md::MDString)

Get the string value of the given string metadata node.

source
LLVM.MDNode — Type
MDNode

Abstract supertype for metadata nodes that can have operands.

See also: MDTuple for a concrete subtype.

source
LLVM.MDNode — Method
MDNode(vals::Vector) -> MDTuple

Create a new tuple metadata node from the given operands.

Passing nothing as a value will result in a null operand.

source

Metadata <-> Value

LLVM.Metadata — Method
Metadata(val::Value)

Wrap the given value as metadata, for use in APIs that expect a LLVM.Metadata.

When the value is already metadata wrapped as a value, this will simply return the original metadata.

source
LLVM.Value — Method
Value(md::Metadata)

Wrap the given metadata as a value, for use in APIs that expect a LLVM.Value.

When the metadata is already a value wrapped as metadata, this will simply return the original value.

source

Inspecting and attaching

LLVM.metadata — Method
metadata(inst::Instruction)
metadata(inst::GlobalObject)

Iterate over the metadata of the given instruction or global object.

These iterators are mutable, and implement setindex! and delete! to modify the metadata.

source
LLVM.NamedMDNode — Type
NamedMDNode

A named metadata node, which is a collection of metadata nodes with a name.

source
LLVM.metadata — Method
metadata(mod)

Fetch the module-level named metadata. This can be inspected using a Dict-like interface. Mutation is different: There is no setindex! method, as named metadata is append-only. Instead, fetch the named metadata node using getindex, and push! to it.

source
LLVM.name — Method
name(node::NamedMDNode)

Get the name of the given named metadata node.

source
LLVM.operands — Method
operands(node::NamedMDNode)

Get the operands of the given named metadata node.

source
Base.push! — Method
push!(node::NamedMDNode, val::MDNode)

Add a metadata node to the given named metadata node.

source

Debug information

Location information

LLVM.line — Method
line(location::DILocation)

Get the line number of this debug location.

source
LLVM.column — Function
column(location::DILocation)

Get the column number of this debug location.

source
LLVM.scope — Method
scope(location::DILocation)

Get the local scope associated with this debug location.

source
LLVM.inlined_at — Function
inlined_at(location::DILocation)

Get the "inline at" location associated with this debug location.

source

Variables

LLVM.file — Method
file(var::DIVariable)

Get the file of the given variable.

source
LLVM.scope — Method
name(var::DIVariable)

Get the name of the given variable.

source
LLVM.line — Method
line(var::DIVariable)

Get the line number of the given variable.

source

Scopes

LLVM.DIScope — Type
DIScope

Abstract supertype for lexical scopes and types (which are also declaration contexts).

source
LLVM.file — Method
file(scope::DIScope)

Get the metadata of the file associated with a given scope.

source
LLVM.name — Method
name(scope::DIScope)

Get the name of the given scope.

source

File

LLVM.source — Function
source(file::DIFile)

Get the source of the given file, or nothing if the source is not available.

source

Type

Base.sizeof — Method
sizeof(typ::DIType)

Get the size in bits of the given type.

source
LLVM.offset — Method
offset(typ::DIType)

Get the offset in bits of the given type.

source
LLVM.line — Method
line(typ::DIType)

Get the line number of the given type.

source

Subprogram

LLVM.line — Method
line(subprogram::DISubProgram)

Get the line number of the given subprogram.

source

Compile Unit

Other

LLVM.subprogram — Method
subprogram(func::Function) -> DISubProgram

Get the subprogram of the given function, or nothing if the function has no subprogram.

source
LLVM.subprogram! — Function
subprogram!(func::Function, sp::DISubProgram)

Set the subprogram of the given function.
