🧹 Outside diff range and nitpick comments (6)
test/support/ref_mod.ex (3)

1-4: Consider documenting the purpose of this module and its usage of Charms.

The module uses the Charms library, which seems to provide a custom DSL. It would be helpful to add a module documentation explaining its purpose and how it integrates with Charms.


9-11: Clarify the purpose of term_roundtrip1/1 and its relation to term_roundtrip0/2.

The function term_roundtrip1/1 seems to do the same thing as term_roundtrip0/2, but with one less parameter. Consider:

  1. Documenting the purpose of this function and how it differs from term_roundtrip0/2.
  2. If they serve the same purpose, consider consolidating them into a single function.

14-17: Consider documenting the purpose of this module and its relationship with RefereeMod.

The module seems to be closely related to RefereeMod. It would be helpful to add module documentation explaining its purpose and how it interacts with RefereeMod.

test/defm_test.exs (1)

51-52: LGTM: Improved JIT initialization and code clarity.

The changes enhance the test by:

  1. Capturing and verifying the JIT initialization key.
  2. Improving the readability of conditional statements.

These modifications add an extra layer of verification and make the test more maintainable.

Consider extracting the :add_int atom into a module attribute for better maintainability:

@test_jit_name :add_int

# Then use @test_jit_name instead of :add_int in the test

Also applies to: 67-68

bench/enif_tim_sort.ex (1)

Line range hint 30-30: Consider making the run size adaptive

The tim_sort function uses a fixed run size of 32. While this is a common choice, consider making the run size adaptive based on the input size for potentially better performance on varying input lengths.

Here's a suggestion for an adaptive run size:

run = max(32, min(64, n / 2))

This approach ensures the run size is between 32 and 64, and scales with the input size for larger arrays.

bench/sort_util.ex (1)

6-6: Simplify the calculation of n1

The expression in line 6:

n1 = m - l + 1 - 1 + 1

Simplifies to:

n1 = m - l + 1

Consider simplifying the expression for clarity and readability.

Apply this diff to simplify the expression:

-n1 = m - l + 1 - 1 + 1
+n1 = m - l + 1

test/support/ref_mod.ex (1)

1-23: Verify the necessity of circular references between modules.

The PR title mentions "Ban reference loop", but this file introduces two modules that seem to reference each other. ReferrerMod calls functions from RefereeMod, which might create a circular dependency. Please verify if this is intentional and aligns with the PR objectives.

To check for other potential circular references, you can run:

Consider refactoring to avoid circular dependencies if they are not intentional. This could involve:

  1. Moving shared functionality to a separate module.
  2. Rethinking the module structure to have a clear hierarchy.
  3. Using callbacks or behaviors instead of direct references if appropriate.
test/defm_test.exs (2)

29-35: LGTM: New test case improves module interface verification.

This new test case effectively verifies the export status of functions in the RefereeMod module. It ensures that only the intended functions are exposed, which is crucial for maintaining proper encapsulation and module interface integrity.


94-96: Verify changes in JIT destruction process.

The modifications to the cleanup assertions are good:

  1. The expected result for Charms.JIT.destroy(ENIFMergeSort) has changed from :noop to :ok.
  2. A new assertion for destroying SortUtil has been added.

These changes suggest updates to the JIT destruction process and the addition of a new module to be cleaned up.

To ensure consistency, let's verify the changes in the Charms.JIT.destroy function:

bench/enif_tim_sort.ex (1)

Line range hint 1-1: Clarify how the PR objective "Ban reference loop" is addressed

The PR title mentions "Ban reference loop", but it's not immediately clear how this objective is met by the current changes. Could you please elaborate on how this change contributes to banning reference loops? This information would be valuable for reviewers and future maintainers.

To help clarify this, could you provide more context on:

  1. What specific reference loops were problematic?
  2. How does moving the merge operation to SortUtil address this issue?
  3. Are there any other changes in the PR that contribute to this objective?
test/expander_test.exs (1)

163-163: Approved: More flexible pattern matching, but verify Charms.JIT.init/2 contract.

The change to use {_key, %Charms.JIT{}} instead of {:ok, %Charms.JIT{}} makes the test more flexible, allowing for any key in the returned tuple. This is good for accommodating potential changes in the Charms.JIT.init/2 function's return value.

To ensure this change aligns with the intended behavior of Charms.JIT.init/2, please run the following script:

This will help confirm whether the function's contract has changed or if the more flexible pattern is intended to accommodate multiple success states.

lib/charms/defm/expander.ex (4)

672-672: Minor improvement in symbol name generation

The change from using SHA256 to erlang:phash2/1 for generating symbol names is a good optimization. This should provide faster symbol name generation while still maintaining a low probability of collisions.


Line range hint 962-989: New macro expansion for :op improves flexibility

This new expand_macro/5 clause for the :op macro enhances the module's capability to handle MLIR operations more flexibly. Here are the key improvements:

  1. It now uses the new decompose_call_signature/1 function to separate the call and return types.
  2. The dialect and operation are extracted from the call, allowing for dynamic operation creation.
  3. It handles both inferred and explicitly specified return types.
  4. The creation of the MLIR operation is now more streamlined and consistent with other parts of the module.

These changes should make it easier to work with various MLIR operations within the macro system.


1211-1221: New decompose_call_signature/1 function improves code organization

The addition of the decompose_call_signature/1 function is a good refactoring step. It separates the logic for decomposing call signatures from the macro expansion logic, which improves code organization and reusability.

The function handles two cases:

  1. Calls with an explicit return type (using the :: operator).
  2. Calls without an explicit return type.

This separation of concerns makes the code more maintainable and easier to understand.


Line range hint 672-1221: Overall improvements in symbol generation, macro expansion, and code organization

The changes in this file represent significant improvements to the Charms.Defm.Expander module:

  1. The symbol name generation has been optimized by using erlang:phash2/1 instead of SHA256.
  2. The macro expansion system has been enhanced to handle MLIR operations more flexibly, particularly with the new :op macro expansion.
  3. The introduction of the decompose_call_signature/1 function improves code organization and reusability.

These changes should result in better performance, increased flexibility in handling MLIR operations, and improved maintainability of the codebase.

bench/enif_merge_sort.ex (2)

Line range hint 5-22: Code changes are appropriate and maintain functionality

The restructuring of the ENIFMergeSort module by moving the merge functionality to SortUtil enhances modularity and reusability. The updated call in the do_sort function correctly delegates the merge operation to SortUtil.merge, and the overall logic of the sorting algorithm remains intact.


13-13: Verify that SortUtil.merge/4 is defined and compatible

Please confirm that the SortUtil module defines the merge/4 function with the expected parameters and behavior. This verification ensures that the refactoring does not introduce any discrepancies or runtime errors due to differences in the merge implementation.

Run the following script to confirm that SortUtil defines the merge/4 function:

mix.exs (3)

12-13: Integration of documentation options looks good

The addition of docs: docs() integrates the documentation options into the project's configuration correctly.


37-62: Injection of Mermaid scripts for documentation rendering

The before_closing_head_tag/1 function correctly injects the necessary scripts to render Mermaid diagrams in the generated documentation. This enhances the documentation by allowing inline diagrams.


64-68: Documentation configuration is set up correctly

The docs/0 function correctly specifies the documentation options, including the before_closing_head_tag callback for injecting custom scripts.

bench/sort_util.ex (4)

5-5: Confirm the usage of defm for function definition

You are using defm to define the merge function. Please ensure that defm is the appropriate macro or function for defining this function within the context of the Charms library.


9-10: Ensure proper memory management for allocated pointers

The pointers left_temp and right_temp are allocated using Pointer.allocate. Ensure that any allocated memory is properly managed and deallocated if necessary to prevent memory leaks.

Would you like assistance in verifying if the allocated memory is correctly deallocated?


33-58: Review the condition within the main merging loop

In the while_loop starting at line 33, the condition is:

while_loop(Pointer.load(i32(), i_ptr) < n1 && Pointer.load(i32(), j_ptr) < n2) do

Ensure that this condition correctly represents the intended logic for merging the subarrays, and verify that the pointers i_ptr, j_ptr, and k_ptr are being updated appropriately within the loop.


60-84: Confirm the correctness of the remaining elements copy loops

The while_loops starting at lines 60 and 73 handle copying any remaining elements from left_temp and right_temp to the original array. Verify that these loops correctly handle the copying process and that the indices and pointers are managed properly.

lib/charms.ex (5)

39-40: Definition of __use_ir__ is appropriate

The function __use_ir__ is correctly defined and marked with @doc false to exclude it from generated documentation.


48-59: Proper handling of referenced modules in __before_compile__/1

The updated __before_compile__/1 macro correctly processes defm declarations and compiles them. The logic that iterates over referenced_modules and excludes env.module effectively prevents self-referencing, which helps avoid circular dependencies.


61-70: Efficient computation of @ir_hash

The computation of @ir_hash by combining the hash of @ir with hashes from referenced modules is well-implemented. Excluding __MODULE__ in the recursive hash gathering prevents self-referencing issues.


77-81: __ir__hash__ function is correctly implemented

The __ir__hash__ function properly returns @ir_hash and is marked with @doc false to keep it internal.


95-95: Simplification of the defm macro definition

The defm macro now directly delegates to Charms.Defm.Definition.declare/3, which simplifies the macro and improves maintainability.

lib/charms/jit.ex (4)

5-5: Approved: Alias LockedCache correctly added

The alias for LockedCache from __MODULE__ is appropriately added and enhances code readability.


132-137: Approved: Introduction of key_of_module/1 function

The new key_of_module(module) function enhances code clarity by encapsulating the key generation logic and safely checks if module exports __ir__hash__/0 before calling it. This improvement helps prevent potential runtime errors and promotes code maintainability.


144-145: Approved: Consistent use of key_of_module/1 in engine/1

The usage of key_of_module(module) in the engine/1 function ensures consistent key retrieval and aligns with the updated key management strategy.


153-155: Approved: Consistent key usage in destroy/1 function

Using key_of_module(module) in the destroy/1 function maintains consistency across the module and ensures that keys are accurately derived for cache operations.

test/defm_test.exs (2)

29-35: LGTM! Consider adding a comment for clarity.

The new test case effectively verifies the export behavior of functions defined with the defm macro. It ensures that only the correct functions are exported and accessible.

Consider adding a brief comment explaining the purpose of this test, e.g.:

# Verify that only the correct functions are exported when using the `defm` macro

51-52: LGTM! Consider using consistent formatting for conditionals.

The changes improve code readability and add a valuable assertion for the JIT initialization process. The new key assertion enhances the test's robustness.

For consistency, consider formatting the nested cond_br statement similarly to the outer one:

cond_br enif_get_int64(env, a, ptr_a) != 0 do
  cond_br enif_get_int64(env, b, ptr_b) != 0 do
    # ... (rest of the code)

123-126: ⚠️ Potential issue

Potential issue: Incorrect use of module in for loop guard

The guard condition when is_atom(module) uses module from the outer scope instead of m. This may not filter the list as intended. Consider changing it to when is_atom(m) to correctly check each element in the list.

Apply this diff to correct the guard:

-for m when is_atom(module) <- modules,
+for m when is_atom(m) <- modules,
lib/charms/defm/definition.ex (4)

1-41: LGTM: Well-documented module with appropriate imports

The module documentation provides a clear and comprehensive overview of the compilation process, including a helpful mermaid diagram. The imports and aliases are appropriate for the module's functionality.


100-110: LGTM: Well-implemented declare/3 function

🧹 Outside diff range and nitpick comments (5)
lib/charms.ex (3)

48-81: LGTM! Consider adding explanatory comments.

The changes to the __before_compile__ macro significantly enhance the handling of intermediate representations and module references. The new logic for preventing circular dependencies is a valuable addition.

To improve maintainability, consider adding comments explaining:

  1. The purpose of the __ir_digest__/0 function.
  2. The rationale behind the module reference checking logic.
  3. The significance of the @ir_hash attribute.

These comments would help future developers understand the intent behind these complex operations.


95-97: LGTM! Consider updating the documentation.

The simplification of the defm macro is a great improvement. Delegating the complexity to Charms.Defm.Definition.declare/3 enhances maintainability and readability.

To keep the documentation in sync with the implementation:

  1. Update the @doc string for the defm macro to reflect its new, simpler implementation.
  2. Consider adding a link or reference to the Charms.Defm.Definition module for developers who need to understand the underlying complexity.

Line range hint 1-97: Consider adding tests for new functionality.

The changes to the Charms module introduce significant enhancements, particularly in IR handling and preventing circular dependencies. To ensure the robustness of these new features, consider adding or updating tests to cover:

  1. The new __use_ir__ and __ir_digest__ functions.
  2. The circular dependency prevention mechanism.
  3. The simplified defm macro with its delegation to Charms.Defm.Definition.declare/3.

These tests would help validate the new functionality and protect against future regressions.

Would you like assistance in drafting some example test cases for these new features?

135-175: Effective implementation of safety checks and optimizations

The check_poison!/1 and append_missing_return/1 functions implement important safety checks and optimizations for the IR. The pattern matching in append_missing_return/1 effectively handles different cases.

However, there's room for improvement in the error handling of check_poison!/1:

Enhance exception handling for better debugging

Consider applying this change to improve the raised exception:

-          |> raise
+          |> (&raise ArgumentError, message: &1).()

This change creates an ArgumentError with a detailed message, which is more idiomatic and provides clearer information for debugging.


200-248: Comprehensive compilation process with room for improvement

The compile/1 function implements a thorough compilation process, including the creation of MLIR structures, expansion of definitions, and application of various passes. The extract_mangled_mod/1 function effectively handles the extraction of module names from mangled names.

However, the compile/1 function is quite extensive and could benefit from refactoring:

Consider refactoring compile/1 for improved readability

The function could be broken down into smaller, well-named helper functions. For example:

  1. Extract the MLIR module creation into a separate function.
  2. Move the definition expansion loop into its own function.
  3. Separate the pass composition and execution into another function.

This refactoring could result in a clearer compile/1 function that orchestrates the compilation process more transparently:

def compile(definitions) when is_list(definitions) do
  ctx = create_mlir_context()
  m = create_mlir_module(ctx)

  expand_definitions(definitions, ctx, m)
  |> run_passes(ctx)
  |> handle_compilation_result(ctx)
end

This approach would make the overall compilation process easier to understand and maintain.

23-23: Improved test assertion specificity

The change to include the error type (ArgumentError) in the assertion is a good improvement. It makes the test more precise by ensuring not only the presence of the error message but also the correct error type. This enhancement reduces the likelihood of false positives and aligns with best practices in testing.

3-5: Improved module documentation

The updated module documentation provides clearer and more specific information about the purpose and functionality of Charms.Defm. It now accurately describes the module as a DSL for defining JIT-compilable functions and specifies its role in defining the defm DSL syntax.

Additionally, the grammatical error mentioned in a previous review has been corrected.


1-1: Verify the impact of removed dependencies and functions

Several require and use statements have been removed, along with multiple private functions. While these changes are not visible in the provided code, they could significantly impact the module's behavior and its integration with other parts of the system.

  1. Could you provide more information about why these dependencies and functions were removed?
  2. How has the implementation of compile_definitions been affected by these changes?
  3. Have you thoroughly tested the module to ensure it still functions correctly after these removals?

To help verify the impact of these changes, you can run the following script:

This script will help identify any lingering references to removed dependencies or functions, and show the current implementation of compile_definitions.

31-31: LGTM! Improved module description.

The description for Charms.Intrinsic has been updated as suggested in the previous review. The new wording is clearer and more accurately describes the module's purpose.


39-40: Please clarify the purpose of __use_ir__/0.

A new private function __use_ir__/0 has been added, which returns nil. Could you please explain the intended purpose of this function? Understanding its role would help in assessing its implementation and potential impact on the module's behavior.


95-97: Verify the impact of removed code.

The simplification of the defm macro involves removing significant portions of the old implementation. While this is generally a positive change, it's crucial to ensure that all necessary functionality has been maintained.

Could you please confirm that:

  1. All use cases supported by the old implementation are still supported?
  2. There are no breaking changes for existing users of the defm macro?
  3. If there are any breaking changes, they are documented and a migration path is provided?

1-35: Excellent module documentation and structure

The module definition and documentation are well-crafted. The comprehensive explanation of the compilation process, including the mermaid diagram, provides clear insights into the module's purpose and functionality. This level of detail will greatly aid developers in understanding and using the module effectively.


37-42: Well-structured module setup and struct definition

The module setup with required modules and aliases is appropriate. The struct definition comprehensively captures all necessary information for a function definition, which will facilitate easier manipulation and processing of function data throughout the module.


44-60: Effective implementation of new/3 function

The new/3 function efficiently creates and initializes a new struct instance. The processing of the call signature, normalization of the call, and determination of the exported flag using match?/2 are well-implemented. This function provides a solid foundation for creating function definitions within the module.


104-133: Comprehensive implementation of normalize_call/1

The normalize_call/1 function effectively normalizes function calls by processing their arguments. It handles special cases for env and term arguments, and wraps arguments with appropriate type specifications. This implementation ensures that function calls are consistently formatted and typed throughout the module, which is crucial for reliable JIT compilation and invocation.


176-198: Efficient implementation of referenced_modules/1

The referenced_modules/1 function effectively extracts referenced modules from the IR. It uses Beaver.Walker.postwalk/3 to traverse the IR efficiently, handling "func.call" operations and extracting module names from the callee attribute. The use of MapSet ensures that only unique module references are collected. The separation of mangled module name extraction into extract_mangled_mod/1 promotes code modularity and reusability.
