+# This script is a helper to verify canonicalization patterns using Alive2
+# https://alive2.llvm.org/ce/.
+# It performs the following steps:
+# - Filters out the provided test functions.
+# - Runs the canonicalization pass on the remaining functions.
+# - Lowers both the original and the canonicalized functions to LLVM IR.
+# - Prints the canonicalized and the original functions side-by-side in a format
+#   that can be copied into Alive2 for verification.
+# Example: `python verify_canon.py canonicalize.mlir -f func1 func2 func3`
