This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0 since I forgot the lit.local.cfg files in that one. Reformatting is done with `black`. If you end up having problems merging this commit because you have made changes to a python file, the best way to handle that is to run git checkout --ours <yourfile> and then reformat it with black. If you run into any problems, post to discourse about it and we will try to help.

# %ProtectFileCheckOutput should precede a FileCheck call if and only if the
|
|
# call's textual output affects test results. It's usually easy to tell: just
|
|
# look for redirection or piping of the FileCheck call's stdout or stderr.
|
|
#
|
|
# Examples:
|
|
#
|
|
# ; Test another program, using FileCheck to verify its textual output.
|
|
# ; Only FileCheck's exit status affects test results, so a bare FileCheck
|
|
# ; call is sufficient and more convenient for debugging.
|
|

|
|
# ; RUN: %t | FileCheck %s

|
# ; CHECK: {{[0-9]+\.0}}

|
|

|
# developers set FileCheck environment variables (e.g.,
|
|
# FILECHECK_OPTS=-dump-input=fail) to tweak the output of FileCheck while
|
|
# debugging tests. If a developer sets values that affect FileCheck's exit
|
|
# status (e.g., FILECHECK_OPTS=-strict-whitespace), he shouldn't be surprised
|
|
# that test results throughout all test suites are affected.
