[Driver] Refactor to use llvm Option's new Visibility flags

[bogner]

Summary

This is a big refactor of the clang driver's option handling to use
the Visibility flags introduced in https://reviews.llvm.org/D157149.
There are a few distinct parts, but they can't really be split into
separate commits and still be made to compile.

1. We split out some of the flags in ClangFlags to ClangVisibility. Note that this does not include any subtractive flags.

2. We update the Flag definitions and OptIn/OptOut constructs in Options.td by hand.

3. We introduce and use a script, update_options_td_flags, to ease migration of flag definitions in Options.td, and we run that on Options.td. I intend to remove this later, but I'm committing it so that downstream forks can use the script to simplify merging.

4. We update calls to OptTable in the clang driver, cc1as, flang, and clangd to use the visibility APIs instead of Include/Exclude flags.

5. We deprecate the Include/Exclude APIs and add a release note.

*if you are running into conflicts with this change:*

Note that https://reviews.llvm.org/D157150 may also be the culprit and
if so it should be handled first.

The script in clang/utils/update_options_td_flags.py can help. Take
the downstream side of all conflicts and then run the following:

% cd clang/include/clang/Driver
% ../../../utils/update_options_td_flags.py Options.td > Options.td.new
% mv Options.td.new Options.td

This will hopefully be sufficient, please take a look at the diff.

Hey @bogner , I've only skimmed through so far and it's looking great! That Include/Exclude API was not fun to use. What you are proposing here takes Options.td to a much a better place - this is a much needed and long overdue refactor.

There's quite a bit of churn here, so I will need a few days to scan. In the meantime, could you update flang/docs/FlangDriver.md? And in general, please note that this updates (primarily) clangDriver logic, which is used by both by Clang and Flang. In particular, Options.td is shared. I think that it's worth highlighting that this change benefits both sub-projects.

Yep, sorry about that. I tried to break this up as much as I could but given the number of places that depend on Options.td it was tricky. I do think this should makes things much easier for flang's driver in particular, as well as making clang-cl and clang-dxc easier to deal with.

Sorry I missed updating FlangDriver.md - FWIW I did build flang and run those tests with this change. I'll update the patch with doc updates momentarily.

I've updated the description to mention https://reviews.llvm.org/D157149.

clang/include/clang/Driver/Options.h

• CoreOption meant "available in clang and clang-cl (and maybe dxc...)", so it's now [Default, CLOption].
• NoDriverOption is !Default - negative flags were a big part of why the include/exclude thing was awkward, so the change in https://reviews.llvm.org/D157149 introduced a bit for options where you don't say anything specific, which meant the clang driver in practice.

For a complete map, see flag_to_vis in the update_options_td_flags.py helper script I provided for downstreams: https://reviews.llvm.org/D157151#change-FMUYy4yRDQLQ

198–200

If you don't specify any visibility, the visibility is "Default" (See https://reviews.llvm.org/D157149). For all intents and purposes this means "Clang Driver" in this file.

Update FlangDriver.md

[awarzynski]

I've tested this locally and can confirm that the behavior of clang and flang-new has been preserved (as in, these changes won't be visible to the end users). Nice!

I think that it would be good to replace Default with e.g.

• Clang, or
• ClangDriver, or
• ClangCompilerDriver.

Or, at least, to make the meaning of Default much clearer (through e.g. comments). In general, I feel that Default is skewed towards this notion that clang (the compiler driver tool) is the main client of clangDriver. That used to be the case, but with Flang's driver also implemented in terms of clangDriver , that's no longer the case. Also, the long term goal is to extract the driver library out of Clang. One day :)

Also, note that Default options will be available in both clang and flang-new. That's the case today (so not something affected by your changes). Ideally, Flang should be able to disable those _Clang options_. That's not possible ATM. Contrary to Flang, Clang can disable _Flang options_ with FlangOnlyOption. There is no such flag for Flang ATM, but I think that we could re-use Default for that. WDYT?

clang/docs/InternalsManual.rst

667–668

IMHO, the difference between Flags and Vis is still unclear. Lets take this opportunity to refine this. IIUC:

• vis should be used to specify the drivers in which a particular option would be available. This attribute will impact tool --help,
• flags can be used to limit the contexts in which a particular option/flag can be used (e.g. NoXarchOption or LinkerOption).

682–687

"Clang driver" could mean two things:

• clangDriver - the driver library shared between Clang and Flang,
• clang - Clang's compiler driver implemented in terms of clangDriver library.

I think that it's important to distinguish between the two in this document. In particular, the meaning of Default is confusing. Is the the default for the library (clangDriver) or the Clang compiler driver binary, clang. I believe it's the latter, but this wording suggests the former.

I appreciate that this wording pre-dates your patch (and probably Flang), but I think that it's worth taking this opportunity to refine this.

This is a little bit complicated by the fact that the Option library is already partially extracted out of clang (and used for other drivers, like lld and lldb). The "Default" visibility is defined in llvm's Option library, so calling it something like "Clang" would be pretty confusing for users that aren't the clang Driver library. I suppose one option would be to throw something like using ClangDriver = llvm::Driver::Default; in Options.h inside the clang::driver::options namespace, and then using the alias in Options.td. Would that help?

Also, note that Default options will be available in both clang and flang-new. That's the case today (so not something affected by your changes).

Default options are either options that don't specify Vis at all or explicitly mention Default. They are not visible in flang-new after this change unless they also specify FlangOption. Specifically, instead of having to deal with FlangOnlyOption we explicitly opt in to default. Some examples:

def default : Flag<["-"], "a">; //visible only in invocations of `clang`
def default_explicit : Flag<["-"], "b">, Vis<[Default]>; //visible only in invocations of `clang`
def flang_only : Flag<["-"], "c">, Vis<[FlangOption]>; // only `flang-new`
def flang_and_clang : Flag<["-"], "d">, Vis<[Default, FlangOption]>; // Both `clang` and `flang-new`
def flang_fc1 : Flag<["-"], "e">, Vis<[FC1Option]>; // `flang-new -fc1`, but not the `flang-new` driver or `clang`

Ah, I see. I guess clangDriver is a bit unique in the sense that there's quite a few drivers that rely on its Options.td:

• clang, clang -cc1, clang -cc1as, clang-cl,
• flang-new, flang-new -fc1.

I suppose one option would be to throw something like using ClangDriver = llvm::Driver::Default; in Options.h inside the clang::driver::options namespace, and then using the alias in Options.td. Would that help?

That would make sense to me, yes. Otherwise the meaning of Default is unclear. These things tend to be obvious to folks familiar with the implementation. However, Options.td would normally be edited/updated by people less familiar with the fine details and more concerned about their favorite option and how it's implemented in their favorite tool.

Default options are either options that don't specify Vis at all or explicitly mention Default. They are not visible in flang-new after this change unless they also specify FlangOption.

That's not quite true ATM. Although not used, the following C++ option _is visible_ in flang-new:

flang-new -fno-experimental-relative-c++-abi-vtables file.f90
flang-new: warning: argument unused during compilation: '-fno-experimental-relative-c++-abi-vtables'

This can be tweaked in getOptionVisibilityMask (extracted from this patch):

llvm::opt::Visibility
Driver::getOptionVisibilityMask(bool UseDriverMode) const {
  if (!UseDriverMode)
    return llvm::opt::Visibility(llvm::opt::Default);
  if (IsCLMode())
    return llvm::opt::Visibility(options::CLOption);
  if (IsDXCMode())
    return llvm::opt::Visibility(options::DXCOption);
  if (IsFlangMode()) {
    // vvvvvvvvvvvvvvv HERE vvvvvvvvvvvvvvvvvvv
    // TODO: Does flang really want *all* of the clang driver options?
    // We probably need to annotate more specifically.
    return llvm::opt::Visibility(llvm::opt::Default | options::FlangOption);
  }
  return llvm::opt::Visibility(llvm::opt::Default);
}

Now, prior to this change I couldn't find a way to disable unsupported Clang options in Flang. With this patch,

• all Clang options gain a visibility flag (atm that's Default),
• that flag can be used to disable options unsupported in Flang.

For this to work, all options supported by Flang need to have their visibility flags set accordingly. That's the goal, but I can see that we have missed quite a few options over the time (*). Updated here: https://reviews.llvm.org/D157837.

(*) There was no mechanism to enforce that. This is now changing.

[bogner]

Update to use "ClangOption" instead of "Default" (See https://reviews.llvm.org/D157150 for the introduction of the name), and address documentation comments.

Ah right. Yes, this is exactly the problem that this patch is trying to fix. Glad to see that it seems to be working as intended for flang-new!

[bogner]

Rebased and finished the changes to use ClangOption everywhere instead of DefaultVis. I think this is good to go now, please take a look.

[awarzynski]

While quite extensive, I find the overall logic in this patch very well structured and executed in a very clean manner. It removes a lot of ambiguity, makes the overall design much easier to reason about and will definitely improve the overall health of the project. The benefits for LLVM Flang are almost immediate, see https://reviews.llvm.org/D157837. Thank you for implementing this, reviewing such patches is very satisfying and rewarding.

This might cause some disruption to downstream consumers of this API and Options.td. Hopefully, "update_options_td_flags.py" that you've included should minimise that. I suggest "advertising" it in the summary a bit more.

LGTM, great work, thank you!

EDIT When landing this, could you send a PSA to Discourse to make folks aware of what's coming? I am primarily concerned about our downstream users.

     MarshallingInfoNegativeFlag<CodeGenOpts<"AsmVerbose">>;
 
 **Negative and Positive Flag**
 
 The key path defaults to the specified value (``false``, ``true`` or some
 boolean value that's statically unknown in the tablegen file). Then, the key
 path is set to the value associated with the flag that appears last on command
 line.
 
 .. code-block:: text

 With most such pair of flags, the ``-cc1`` frontend accepts only the flag that
 changes the default key path value. The Clang driver is responsible for
 accepting both and either forwarding the changing flag or discarding the flag
 that would just set the key path to its default.
 
 The first argument to ``BoolOption`` is a prefix that is used to construct the
 full names of both flags. The positive flag would then be named
 ``flegacy-pass-manager`` and the negative ``fno-legacy-pass-manager``.
 ``BoolOption`` also implies the ``-`` prefix for both flags. It's also possible
 to use ``BoolFOption`` that implies the ``"f"`` prefix and ``Group<f_Group>``.
-The ``PosFlag`` and ``NegFlag`` classes hold the associated boolean value, an
-array of elements passed to the ``Flag`` class and the help text. The optional
-``BothFlags`` class holds an array of ``Flag`` elements that are common for both

+and their common help text suffix.
 
 **String**
 
 The key path defaults to the specified string, or an empty one, if omitted. When
 the option appears on the command line, the argument value is simply copied.

-  def isysroot : JoinedOrSeparate<["-"], "isysroot">, Flags<[CC1Option]>,
+  def isysroot : JoinedOrSeparate<["-"], "isysroot">,

     MarshallingInfoString<HeaderSearchOpts<"Sysroot">, [{"/"}]>;
 
 **List of Strings**
 
 The key path defaults to an empty ``std::vector<std::string>``. Values specified
 with each appearance of the option on the command line are appended to the
 vector.
 
 .. code-block:: text
 
-  def frewrite_map_file : Separate<["-"], "frewrite-map-file">, Flags<[CC1Option]>,
+  def frewrite_map_file : Separate<["-"], "frewrite-map-file">,
+    Visibility<[ClangOption, CC1Option]>,
     MarshallingInfoStringVector<CodeGenOpts<"RewriteMapFiles">>;
 
 **Integer**
 
 The key path defaults to the specified integer value, or ``0`` if omitted. When
 the option appears on the command line, its value gets parsed by ``llvm::APInt``
 and the result is assigned to the key path on success.
 
 .. code-block:: text

     MarshallingInfoInt<CodeGenOpts<"StackProbeSize">, "4096">;
 
 **Enumeration**
 
 The key path defaults to the value specified in ``MarshallingInfoEnum`` prefixed
 by the contents of ``NormalizedValuesScope`` and ``::``. This ensures correct
 reference to an enum case is formed even if the enum resides in different
 namespace or is an enum class. If the value present on command line does not
 match any of the comma-separated values from ``Values``, an error diagnostics is
 issued. Otherwise, the corresponding element from ``NormalizedValues`` at the
 same index is assigned to the key path (also correctly scoped). The number of
 comma-separated string values and elements of the array within
 ``NormalizedValues`` must match.

   Intentionally omitting MarshallingInfoBitfieldFlag. It's adding some
   complexity to the marshalling infrastructure and might be removed.
 
 It is also possible to define relationships between options.
 
 **Implication**
 
 The key path defaults to the default value from the primary ``Marshalling``
 annotation. Then, if any of the elements of ``ImpliedByAnyOf`` evaluate to true,
 the key path value is changed to the specified value or ``true`` if missing.
 Finally, the command line is parsed according to the primary annotation.

 **Condition**
 
 The option is parsed only if the expression in ``ShouldParseIf`` evaluates to
 true.

* add a completely new definition if the option that you are adding has not
     been defined yet.
 
 There are many predefined TableGen classes and records that you can use to fine
 tune your new option. The list of available configurations can be overwhelming
 at times. Sometimes the easiest approach is to find an existing option that has
 similar semantics to your new option and start by copying that.
 
 For every new option, you will also have to define the visibility of the new
-option. This is controlled through the `Flags` field. You can use the following
-Flang specific option flags to control this:
+option. This is controlled through the `Visibility` field. You can use the
+following Flang specific visibility flags to control this:
   * `FlangOption` - this option will be available in the `flang-new` compiler driver,
   * `FC1Option` - this option will be available in the `flang-new -fc1` frontend driver,
-  * `FlangOnlyOption` - this option will not be visible in Clang drivers.
 
-Please make sure that options that you add are only visible in drivers that can
-support it. For example, options that only make sense for Fortran input files
-(e.g. `-ffree-form`) should not be visible in Clang and be marked as
-`FlangOnlyOption`.
+Options that are supported by clang should explicitly specify `ClangOption` in
+`Visibility`, and options that are only supported in Flang should not specify
+`ClangOption`.
 
 When deciding what `OptionGroup` to use when defining a new option in the
 `Options.td` file, many new options fall into one of the following two
 categories:
   * `Action_Group` - options that define an action to run (e.g.
     `-fsyntax-only`, `-E`)
   * `f_Group` - target independent compiler flags (e.g. `-ffixed-form`,
     `-fopenmp`)
 There are also other groups and occasionally you will use them instead of the
 groups listed above.
 
 ### Option Implementation
 First, every option needs to be parsed. Flang compiler options are parsed in
 two different places, depending on which driver they belong to:
 
 * frontend driver: `flang/lib/Frontend/CompilerInvocation.cpp`,
 * compiler driver: `clang/lib/Driver/ToolChains/Flang.cpp`.
 
 The parsing will depend on the semantics encoded in the TableGen definition.
 
 When adding a compiler driver option (i.e. an option that contains
-`FlangOption` among its `Flags`) that you also intend to be understood by the
-frontend, make sure that it is either forwarded to `flang-new -fc1` or translated
-into some other option that is accepted by the frontend driver. In the case of
-options that contain both `FlangOption` and `FC1Option` among its flags, we
-usually just forward from `flang-new` to `flang-new -fc1`. This is then tested in
-`flang/test/Driver/frontend-forward.F90`.
+`FlangOption` among in it's `Visibility`) that you also intend to be understood
+by the frontend, make sure that it is either forwarded to `flang-new -fc1` or
+translated into some other option that is accepted by the frontend driver. In
+the case of options that contain both `FlangOption` and `FC1Option` among its
+flags, we usually just forward from `flang-new` to `flang-new -fc1`. This is
+then tested in `flang/test/Driver/frontend-forward.F90`.
 
 What follows is usually very dependant on the meaning of the corresponding
 option. In general, regular compiler flags (e.g. `-ffree-form`) are mapped to
 some state within the driver. A lot of this state is stored within an instance
 of `FrontendOptions`, but there are other more specialised classes too. Action
 flags (e.g. `-fsyntax-only`) are usually more complex overall, but also more
 structured in terms of the implementation.

 Changes to Sanitizers
 ---------------------
 * HWASan now defaults to detecting use-after-scope bugs.
 
 Other Changes
 -------------
 
+* The ``Flags`` field of ``llvm::opt::Option`` has been split into ``Flags``
+  and ``Visibility`` to simplify option sharing between various drivers (such
+  as ``clang``, ``clang-cl``, or ``flang``) that rely on Clang's Options.td.
+  Overloads of ``llvm::opt::OptTable`` that use ``FlagsToInclude`` have been
+  deprecated. A script to help downstream forks update clang's ``Options.td``
+  has been included in ``clang/utils/update_options_td_flags.py``.
