Module cranelift_codegen::ir::instructions

Instruction formats and opcodes.

The instructions module contains definitions for instruction formats, opcodes, and the in-memory representation of IR instructions.

A large part of this module is auto-generated from the instruction descriptions in the meta directory.

Structs

OpcodeConstraints	Value type constraints for a given opcode.
ValueTypeSet	A value type set describes the permitted set of types for a type variable.
VariableArgs	A variable list of Value operands used for function call arguments and passing arguments to basic blocks.

Enums

BranchInfo	Information about branch and jump instructions.
CallInfo	Information about call instructions.
InstructionData
InstructionFormat	An instruction format
Opcode	An instruction opcode.
ResolvedConstraint	The type constraint on a value argument once the controlling type variable is known.

Type Definitions

ValueList	Some instructions use an external list of argument values because there is not enough space in the 16-byte InstructionData struct. These value lists are stored in a memory pool in dfg.value_lists.
ValueListPool	Memory pool for holding value lists. See ValueList.
