| ## Test that update_test_checks.py can run pre-processing commands. | |
| # RUN: cp -f %S/Inputs/pre-process.ll %t.ll && %update_test_checks --function-signature %t.ll | |
| # RUN: diff -u %t.ll %S/Inputs/pre-process.ll.expected | |
| ## Check that running the script again does not change the result: | |
| # RUN: %update_test_checks %t.ll | |
| # RUN: diff -u %t.ll %S/Inputs/pre-process.ll.expected |
