Modules

binemit

Binary machine code emission.

cfg_printer

The CFGPrinter utility.

cursor

Cursor library.

data_value

This module gives users to instantiate values that Cranelift understands. These values are used, for example, during interpretation and for wrapping immediates.

dbg

Debug tracing helpers.

dominator_tree

A Dominator Tree represented as mappings of Blocks to their immediate dominator.

flowgraph

A control flow graph represented as mappings of basic blocks to their predecessors and successors.

ir

Representation of Cranelift IR functions.

isa

Instruction Set Architectures.

loop_analysis

A loop analysis represented as mappings of loops to their header Block and parent in the loop tree.

packed_option

Compact representation of Option<T> for types with a reserved value.

print_errors

Utility routines for pretty-printing error messages.

settings

Shared settings module.

timing

Pass timing.

verifier

A verifier for ensuring that functions are well formed. It verifies:

write

Converting Cranelift IR to text.

Macros

trace

Even when trace logging is disabled, the trace macro has a significant performance cost so we disable it by default.

Structs

CompileError

Compilation error, with the accompanying function to help printing it.

Context

Persistent data structures and compilation pipeline.

Final

Status of a compiled artifact ready to use.

MachBuffer

A buffer of output to be produced, fixed up, and then emitted to a CodeSink in bulk.

MachBufferFinalized

A MachBuffer once emission is completed: holds generated code and records, without fixups. This allows the type to be independent of the backend.

MachCallSite

A call site record resulting from a compilation.

MachReloc

A relocation resulting from a compilation.

MachSrcLoc

A source-location mapping resulting from a compilation.

MachStackMap

Record of stack map metadata: stack offsets containing references.

MachTrap

A trap record resulting from a compilation.

Reg

A register named in an instruction. This register can be either a virtual register or a fixed physical register. It does not have any constraints applied to it: those can be added later in MachInst::get_operands() when the Regs are converted to Operands.

ValueLocRange

Value location range.

Writable

A type wrapper that indicates a register type is writable. The underlying register can be extracted, and the type wrapper can be built using an arbitrary register. Hence, this type-level wrapper is not strictly a guarantee. However, “casting” to a writable register is an explicit operation for which we can audit. Ordinarily, internal APIs in the compiler backend should take a Writable<Reg> whenever the register is written, and the usual, frictionless way to get one of these is to allocate a new temporary.

MachInstEmit

A trait describing the ability to encode a MachInst into binary machine code.

TextSectionBuilder

An object that can be used to create the text section of an executable.
