## Basic test checking that we capture existing lines matching global variable names
# RUN: cp -f %S/Inputs/global_preserve_name.ll %t.ll && %update_test_checks %t.ll --check-globals --preserve-names
# RUN: diff -u %t.ll %S/Inputs/global_preserve_name.ll.expected
## Verify that running without the --global-value-regex flag respects UTC_ARGS, and that the output is a fixed point.
# RUN: %update_test_checks %t.ll
# RUN: diff -u %t.ll %S/Inputs/global_preserve_name.ll.expected
