  • libeir_passes - Compiler passes operating on Eir.
  • libeir_lowerutils - Utilities for lowering Eir to SSA form.
  • libeir_interpreter - Naive interpreter for Eir. Used to run OTP test suites.
  • libeir_intern - Symbol interning. Used by most other crates.
  • libeir_diagnostics - Source span handling and diagnostics printing.
