Crate wasmer_compiler_cranelift

A WebAssembly Compiler implementation using Cranelift.

Cranelift is a fast IR generator created by Mozilla for usage in Firefox as a next JS compiler generator.

Compared to LLVM, Cranelift is a bit faster and made entirely in Rust.

Modules

address_map 🔒

compiler 🔒

Support for compiling with Cranelift.

config 🔒

debug 🔒

dwarf 🔒

func_environ 🔒

heap 🔒

Heaps to implement WebAssembly linear memories.

table 🔒

trampoline 🔒

translator 🔒

Tools for translating wasm function bytecode to Cranelift IR.

Structs

Cranelift

Global configuration options used to create an wasmer_engine::Engine and customize its behavior.

CraneliftCompiler

A compiler that compiles a WebAssembly module with Cranelift, translating the Wasm to Cranelift IR, optimizing it and then translating to assembly.

ModuleInfoVmctxInfo

ModuleInfo vmctx related info.

Enums

CraneliftOptLevel

Possible optimization levels for the Cranelift codegen backend.

ModuleInfoMemoryOffset

Memory definition offset in the VMContext structure.

Constants

TRAP_BAD_SIGNATURE

Trap reported when an indirect call signature does not match.

TRAP_HEAP_MISALIGNED

Trap reported when a heap access violates alignment guarantees.

TRAP_INDIRECT_CALL_TO_NULL

Trap reported when an indirect call targets a null function reference.

TRAP_INTERRUPT

Trap reported for interrupts (not currently supported).

TRAP_NULL_I31_REF

Trap reported when a null i31 reference is observed.

TRAP_NULL_REFERENCE

Trap reported when a null reference is observed.

TRAP_TABLE_OUT_OF_BOUNDS

Trap reported when a table access goes out of bounds.

TRAP_UNREACHABLE

Trap reported when unreachable code is executed.

TRAP_USER_OFFSET 🔒

Offset applied to user-defined trap codes to avoid colliding with Cranelift-reserved values.

VERSION

Version number of this crate.

Functions

make_trampoline_function_call
