-"""A script to generate FileCheck statements for 'opt' regression tests.
-
-This script is a utility to update LLVM opt test cases with new
-FileCheck patterns. It can either update all of the tests in the file or
-a single test function.
-
-Example usage:
-$ update_test_checks.py --opt=../bin/opt test/foo.ll
-
-Workflow:
-1. Make a compiler patch that requires updating some number of FileCheck lines
-   in regression test files.
-2. Save the patch and revert it from your local work area.
-3. Update the RUN-lines in the affected regression tests to look canonical.
-   Example: "; RUN: opt < %s -instcombine -S | FileCheck %s"
-4. Refresh the FileCheck lines for either the entire file or select functions by
-   running this script.
-5. Commit the fresh baseline of checks.
-6. Apply your patch from step 1 and rebuild your local binaries.
-7. Re-run this script on affected regression tests.
-8. Check the diffs to ensure the script has done something reasonable.
-9. Submit a patch including the regression test diffs for review.
-
-A common pattern is to have the script insert complete checking of every
-instruction. Then, edit it down to only check the relevant instructions.
-The script is designed to make adding checks to a test case fast, it is *not*
-designed to be authoratitive about what constitutes a good test!
