Module module 

LLVM 3.7 IR as DXIL stores it, read from the bitstream tree: the type table, module values (globals, functions, constants), metadata, value names and function bodies. Only what DXIL programs use is decoded; any other record in a function body is refused by name. The blocks of a function body that say nothing a reader of the program’s behaviour needs (its metadata, the metadata attached to its instructions and its use-list order) are the only things skipped.

Structs

Function

A function body.

Instruction

An instruction of a function body.

Module

A module: its types, values, metadata and function bodies.

Enums

BinaryOp

A binary operator code (LLVM’s BinaryOpcodes).

CastOp

A cast opcode (LLVM’s CastOpcodes).

Constant

A module-level constant.

Metadata

A metadata record.

Op

An instruction, with the value ids (absolute) and block numbers it names.

Type

A type of the module’s type table.

Value

A value the module numbers.

Type Aliases

MetadataId

An index into Module::metadata.

TypeId

An index into Module::types.

ValueId

An index into the values: the module’s Module::values, then a function body’s own Function::locals.
