Expand description

This crate generates Rust sources for use by cranelift_codegen.


  • cdsl 🔒
    Cranelift DSL classes.
  • Build support for precomputed constant hash tables.
  • Error returned during meta code-generation.
  • gen_inst 🔒
    Generate instruction data (including opcodes, formats, builders, etc.).
  • Generate the ISA-specific settings.
  • gen_types 🔒
    Generate sources with type info.
  • Define supported ISAs; includes ISA-specific instructions, encodings, registers, settings, etc.
  • shared 🔒
    Shared definitions for the Cranelift intermediate language.
  • srcgen 🔒
    Source code generator.
  • An index-accessed table implementation that avoids duplicate entries.


  • A macro that converts boolean settings into predicates to look more natural.
  • A macro that joins boolean settings into a list (e.g. preset!(feature_a && feature_b)).


  • Generates all the Rust source files used in Cranelift from the meta-language.
  • Generate an ISA from an architecture string (e.g. “x86_64”).
