[SanitizeCoverage] Rename -fsanitize-coverage-{white,black}list to -fsanitize-coverage-{allow,block}list

[MaskRay]

Summary

Keep -fsanitize-coverage-{white,black}list as aliases for compatibility for now.

[MaskRay]

Update more files

[echristo]

You'll want to grab blacklist/whitelist in the comments around as well.

We've been talking about having a need for deprecated aliases file for these options - it's probably worth bringing this patch up on cfe-dev and cc'ing richardsmith explicitly. I think we can avoid compatibility aliases, but would like Richard to sign off.

Fix documentation

Miss merge?

I'd remove the uses of blacklist and whitelist here and below. Just have the language and the documentation be for the new option.

clang/docs/SanitizerCoverage.rst

blacklist here.

clang/include/clang/Driver/Options.td

1002–1005

Deprecate the option and comment it as such.

compiler-rt/test/sanitizer_common/TestCases/sanitizer_coverage_allowlist_blocklist.cpp

blacklist filename. probably want to change wl_* and bl_* below as well.

clang-tblgen -gen-opt-docs does not seem to provide a feature to hide an option. HelpHidden does not hide the option.

clang/docs/SanitizerCoverage.rst

sancov is another tool that is not touched by this patch. It should be updated separately.

clang/include/clang/Driver/Options.td

1002–1005

HelpHidden will hide the options from help.

compiler-rt/test/sanitizer_common/TestCases/sanitizer_coverage_allowlist_blocklist.cpp

wl_ -> al_

bl_ can still mean blocklist.

[MaskRay]

Fix more words

[echristo]

Couple of inline comments then looks good to go. Thank you so much for your effort here.

Please remove blacklist and whitelist from the option description.

compiler-rt/test/sanitizer_common/TestCases/sanitizer_coverage_allowlist_blocklist.cpp

89

Make a note that the options below ware deprecated and will be removed.

[MaskRay]

clang/docs/ClangCommandLineReference.rst

I can do that but the next person updating the documentation will add them back.

I believe clang-tblgen -gen-opt-docs just doesn't have the feature. Maybe we can delete the old options earlier so that we don't need to worry about the documentation.

Ugh. Yes, I hope so too. Can you raise it on cfe-dev?

I can but I need to understand more about clang-tblgen -gen-opt-docs first...

Very few people know how to regenerate the doc I think...

 Partially disabling instrumentation
 ===================================
 
 It is sometimes useful to tell SanitizerCoverage to instrument only a subset of the
 functions in your target.
-With ``-fsanitize-coverage-whitelist=whitelist.txt``
-and ``-fsanitize-coverage-blacklist=blacklist.txt``,
-you can specify such a subset through the combination of a whitelist and a blacklist.
+With ``-fsanitize-coverage-allowlist=allowlist.txt``
+and ``-fsanitize-coverage-blocklist=blocklist.txt``,
+you can specify such a subset through the combination of a allowlist and a blocklist.
 
 SanitizerCoverage will only instrument functions that satisfy two conditions.
-First, the function should belong to a source file with a path that is both whitelisted
-and not blacklisted.
-Second, the function should have a mangled name that is both whitelisted and not blacklisted.
-
-The whitelist and blacklist format is similar to that of the sanitizer blacklist format.
-The default whitelist will match every source file and every function.
-The default blacklist will match no source file and no function.
-
-A common use case is to have the whitelist list folders or source files for which you want
-instrumentation and allow all function names, while the blacklist will opt out some specific
-files or functions that the whitelist loosely allowed.
+First, the function should belong to a source file with a path that is both allowlisted
+and not blocklisted.
+Second, the function should have a mangled name that is both allowlisted and not blocklisted.
+
+The allowlist and blocklist format is similar to that of the sanitizer blocklist format.
+The default allowlist will match every source file and every function.
+The default blocklist will match no source file and no function.
+
+A common use case is to have the allowlist list folders or source files for which you want
+instrumentation and allow all function names, while the blocklist will opt out some specific
+files or functions that the allowlist loosely allowed.
 
-Here is an example whitelist:
+Here is an example allowlist:
 
 .. code-block:: none
 
   # Enable instrumentation for a whole folder
   src:bar/*
   # Enable instrumentation for a specific source file
   src:foo/a.cpp
   # Enable instrumentation for all functions in those files
   fun:*
 
-And an example blacklist:
+And an example blocklist:
 
 .. code-block:: none
 
-  # Disable instrumentation for a specific source file that the whitelist allowed
+  # Disable instrumentation for a specific source file that the allowlist allowed
   src:bar/b.cpp
-  # Disable instrumentation for a specific function that the whitelist allowed
+  # Disable instrumentation for a specific function that the allowlist allowed
   fun:*myFunc*
 
 The use of ``*`` wildcards above is required because function names are matched after mangling.
 Without the wildcards, one would have to write the whole mangled name.
 
 Be careful that the paths of source files are matched exactly as they are provided on the clang
 command line.
-For example, the whitelist above would include file ``bar/b.cpp`` if the path was provided
+For example, the allowlist above would include file ``bar/b.cpp`` if the path was provided
 exactly like this, but would it would fail to include it with other ways to refer to the same
 file such as ``./bar/b.cpp``, or ``bar\b.cpp`` on Windows.
 So, please make sure to always double check that your lists are correctly applied.
