26-28: Consider updating documentation for the new flags parameter.The implementation looks correct and aligns with the fix for
mlirPassManagerEnableIRPrinting/8. Consider updating the function's documentation to explain the purpose and impact of the printing flags.Add documentation above the function explaining the role of printing flags:
@spec enable_ir_printing(MLIR.PassManager.t(), print_opts()) :: :ok + @doc """ + Enables IR printing for the pass manager with customizable printing flags. + The printing flags control the formatting and display options of the IR output. + """ def enable_ir_printing(%MLIR.PassManager{} = pm, opts \\ []) do

1-2: LGTM! Verify version compatibility with mlirPassManagerEnableIRPrinting fix.
The MLIR version upgrade from 20.0.0.2024120301 to 20.0.0.2024120617 appears to be related to the fix for mlirPassManagerEnableIRPrinting/8.
✅ Verification successful
Let me try another verification approach to check the usage of mlirPassManagerEnableIRPrinting in the codebase.
Let me check the actual usage in the identified files to understand the context better.
Version upgrade appears safe for mlirPassManagerEnableIRPrinting usage
The codebase uses mlirPassManagerEnableIRPrinting in a standard way through MLIR.CAPI bindings with proper parameter handling. The version upgrade is minor (same day, different build) and the function signature in the codebase matches the MLIR API contract, making it unlikely to be affected by this version change.

26-26: Verify memory management for OpPrintingFlags.
The mlirOpPrintingFlagsCreate() creates a new flags object, but there's no visible cleanup. Please ensure that the flags object is properly destroyed to prevent memory leaks.
✅ Verification successful
Let me gather more context about the memory management patterns in the codebase.
Let me search for any memory management patterns in the codebase, particularly around OpPrintingFlags.
Let me check if the PassManager module is using any resource management patterns through Kinda.ResourceKind.
Based on the gathered context, I can now provide the final response:
Memory management for OpPrintingFlags is handled by MLIR PassManager.
The PassManager module uses Kinda.ResourceKind which provides automatic resource management. The mlirOpPrintingFlagsCreate() is used as an argument to mlirPassManagerEnableIRPrinting(), and the ownership of the flags is transferred to the PassManager. The PassManager is responsible for cleaning up all its resources, including the printing flags, when it is destroyed via mlirPassManagerDestroy(). This is a common pattern in the codebase, as seen in multiple test files and the Composer module.
