This is a tentative fix which addresses a PR raise regarding Case indentation when working with Whitesmiths Indentation
I could not find online any reference sources as to what the case indentation for Whitesmith's should be (or be allowed to be)
But according to the documentation, we don't obey the rules for Whitesmith's
```
In particular, the documentation states that this option is to "indent case labels one level from the switch statement. When false, use the same indentation level as for the switch statement."
```
The behaviour we add here is actually as the TODO in the tests used to state in {D67627}, but when {D82016} was added and I brought these tests out from being TODO I realized I changed the indentation.

Before this patch, you needed to use `AutoNormalizeEnumJoined` whenever you wanted to **de**normalize joined enum.
Besides the naming confusion, this means the fact the option is joined is specified in two places: in the normalization multiclass and in the `Joined<["-"], ...>` multiclass.
This patch makes this work automatically, taking into account the `OptionClass` of options.
Also, the enum denormalizer now just looks up the spelling of the present enum case in a table and forwards it to the string denormalizer.
I also added more tests that exercise this.

This allows ASTs to be merged when they contain GenericSelectionExpr

The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter. Additionally, this change adds support for structural

If both flags created through BoolOption are CC1Option and the keypath has a non-default or non-implied value, the denormalizer gets called twice. If the denormalizer has the ability to generate both flags, we can end up generating the same flag twice.
Reviewed By: dexonsmith, Bigcheese
Differential Revision: https://reviews.llvm.org/D93094
We cannot be sure whether a flag is CC1Option inside the definition of `BoolOption`. Take the example below:
```
let Flags = [CC1Option] in {
defm xxx : BoolOption<...>;
}
```
where TableGen applies `Flags = [CC1Option]` to the `xxx` and `no_xxx` records **after** they have been is fully declared by `BoolOption`.
For the refactored `-f[no-]debug-pass-manager` flags (see the diff), this means `BoolOption` never adds any marshalling info, as it doesn't see either of the flags as `CC1Option`.
For that reason, we should defensively append the marshalling information to both flags inside `BoolOption`. Now the check for `CC1Option` needs to happen later, in the parsing macro, when all TableGen logic has been resolved.
However, for some flags defined through `BoolOption`, we can run into issues:
```
// Options.td
def fenable_xxx : /* ... */;
// Both flags are CC1Option, the first is implied.
defm xxx : BoolOption<"xxx,
"Opts.Xxx", DefaultsToFalse,
ChangedBy<PosFlag, [CC1Option], "", [fenable_xxx]>,
ResetBy<NegFlag, [CC1Option]>>;
```
When parsing `clang -cc1 -fenable-xxx`:
* we run parsing for `PosFlag`:
* set `Opts.Xxx` to default `false`,
* discover `PosFlag` is implied by `-fenable-xxx`: set `Opts.Xxx` to `true`,
* don't see `-fxxx` on command line: do nothing,
* we run parsing for `NegFlag`:
* set `Opts.Xxx` to default `false`,
* discover `NegFlag` cannot be implied: do nothing,
* don't see `-fno-xxx` on command line: do nothing.
Now we ended up with `Opts.Xxx` set to `false` instead of `true`. For this reason, we need to ensure to append the same `ImpliedByAnyOf` instance to both flags.
This means both parsing runs now behave identically (they set the same default value, run the same "implied by" check, and call `makeBooleanOptionNormalizer` that already has information on both flags, so it returns the same value in both calls).
The solution works well, but what might be confusing is this: you have defined a flag **A** that is not `CC1Option`, but can be implied by another flag **B** that is `CC1Option`:
* if **A** is defined manually, it will never get implied, as the code never runs
```
def no_signed_zeros : Flag<["-"], "fno-signed-zeros">, Group<f_Group>, Flags<[]>,
MarshallingInfoFlag<"LangOpts->NoSignedZero">, ImpliedByAnyOf<[menable_unsafe_fp_math]>;
```
* if **A** is defined by `BoolOption`, it could get implied, as the code is run by its `CC1Option` counterpart:
```
defm signed_zeros : BoolOption<"signed-zeros",
"LangOpts->NoSignedZero", DefaultsToFalse,
ChangedBy<NegFlag, [], "Allow optimizations that ignore the sign of floating point zeros",
[cl_no_signed_zeros, menable_unsafe_fp_math]>,
ResetBy<PosFlag, [CC1Option]>, "f">, Group<f_Group>;
```
This is a surprising inconsistency.
One solution might be to somehow propagate the final `Flags` of the implied flag in `ImpliedByAnyOf` and check whether it has `CC1Option` in the parsing macro. However, I think it doesn't make sense to spend time thinking about a corner case that won't come up in real code.
An observation: it is unfortunate that the marshalling information is a part of the flag definition. If we represented it in a separate structure, we could avoid the "double parsing" problem by having a single source of truth. This would require a lot of additional work though.
Note: the original patch missed the `CC1Option` check in the parsing macro, making my reasoning here incomplete. Moreover, it contained a change to denormalization that wasn't necessarily related to these changes, so I've extracted that to a follow-up patch: D93094.

The fix is to first create the TypedefDecl and only then start to import

Basically, we could do this during the import of all other Decls (not
just for typedefs). But it seems, there is only one another AST
construct that has a similar cycle: a struct defined as a function
parameter:
```
int struct_in_proto(struct data_t{int a;int b;} *d);
```
In that case, however, we had decided to return simply with an error
back then because that seemed to be a very rare construct.

Clang offers a `-f[no]-show-column` flag for hiding the column numbers when
printing diagnostics but there is no option for doing the same with line
numbers.
In LLDB having this option would be useful, as LLDB sometimes only knows the
file name for a SourceLocation and just assigns it the dummy line/column `1:1`.
These fake line/column numbers are confusing to the user and LLDB should be able
to tell clang to hide *both* the column and the line number when rendering text
diagnostics.
This patch adds a flag for also hiding the line numbers. It's not exposed via
the command line flags as it's most likely not very useful for any user and can
lead to ambiguous output when the user decides to only hide either the line or
the column number (where `file:1: ...` could now refer to both line 1 or column
1 depending on the compiler flags). LLDB can just access the DiagnosticOptions
directly when constructing its internal Clang instance.
The effect doesn't apply to Vi/MSVC style diagnostics because it's not defined
how these diagnostic styles would show an omitted line number (MSVC doesn't have
such an option and Vi's line mode is theory only supporting line numbers if I
understand it correctly).

In existing matcher code, users can write

user must know which to use). The point of the
TK_IgnoreUnlessSpelledInSource mode is to allow the novice to avoid such
details. This patch changes the IgnoreUnlessSpelledInSource mode to
skip over implicit template instantiations.
This patch does not change the TK_AsIs mode.
Note: An obvious attempt at an alternative implementation would simply

return something conditional on the operational TraversalKind. That
does not work because shouldVisitTemplateInstantiations() is called

This reverts commit 940d0a310d,
effectively reapplying 84e8257937, after
working around the compile errors on the bots that I wasn't seeing
locally. I removed the `constexpr` from `OptionalStorage<FileEntryRef>`
that I had cargo-culted from the generic version, since `FileEntryRef`
isn't relevant in `constexpr` contexts anyway.
The original commit message follows:
Make a few changes to the `FileEntryRef` API in preparation for
propagating it enough to remove `FileEntry::getName()`.
- Allow `FileEntryRef` to degrade implicitly to `const FileEntry*`. This
allows functions currently returning `const FileEntry *` to be updated
to return `FileEntryRef` without requiring all callers to be updated
in the same patch. This helps avoid both (a) massive patches where
many fields and locals are updated simultaneously and (b) noisy
incremental patches where the first patch adds `getFileEntry()` at
call sites and the second patch removes it. (Once `FileEntryRef` is
everywhere, we should remove this API.)
- Change `operator==` to compare the underlying `FileEntry*`, ignoring
any difference in the spelling of the filename. There were 0 users of
the existing function because it's not useful. In case comparing the
exact named reference becomes important, add/test `isSameRef`.
- Add `==` comparisons between `FileEntryRef` and `const FileEntry *`
(compares the `FileEntry*`).
- Customize `OptionalStorage<FileEntryRef>` to be pointer-sized. Add
a private constructor that initializes with `nullptr` and specialize
`OptionalStorage` to use it. This unblocks updating fields in
size-sensitive data structures that currently use `const FileEntry *`.
- Add `OptionalFileEntryRefDegradesToFileEntryPtr`, a wrapper around
`Optional<FileEntryRef>` that degrades to `const FileEntry*`. This
facilitates future incremental patches, like the same operator on
`FileEntryRef`. (Once `FileEntryRef` is everywhere, we should remove
this class.)
- Remove the unncessary `const` from the by-value return of
`FileEntryRef::getName`.
- Delete the unused function `FileEntry::isOpenForTests`.
Note that there are still `FileEntry` APIs that aren't wrapped and I
plan to deal with these separately / incrementally, as they are needed.

This gives us slightly nicer syntax (foreach) for idioms currently expressed

Shrink `FileEntryRef` to the size of a pointer, by having it directly
reference the `StringMapEntry` the same way that `DirectoryEntryRef`
does. This makes `FileEntryRef::FileEntryRef` private as a side effect
(`FileManager` is a friend!).
There are two helper types added within `FileEntryRef`:
- `FileEntryRef::MapValue` is the type stored in
`FileManager::SeenFileEntries`. It's a replacement for
`SeenFileEntryOrRedirect`, where the second pointer type has been
changed from `StringRef*` to `MapEntry*` (see next bullet).
- `FileEntryRef::MapEntry` is the instantiation of `StringMapEntry<>`
where `MapValue` is stored. This is what `FileEntryRef` has a pointer
to, in order to grab the name in addition to the value.

After D86959 the code `#define lambda [](const decltype(x) &ptr) {}`
was formatted as `#define lambda [](const decltype(x) & ptr) {}` due to
now parsing the '&' token as a BinaryOperator. The problem was caused by
the condition `Line.InPPDirective && (!Left->Previous || !Left->Previous->is(tok::identifier))) {`
being matched and therefore not performing the checks for "previous token
is one of decltype/_Atomic/etc.". This patch moves those checks after the
existing if/else chain to ensure the left-parent token classification is
always run after checking whether the contents of the parens is an

This change also introduces a new TokenAnnotatorTest that checks the
token kind and Role of Tokens after analyzing them. This is used to check
for TT_PointerOrReference, in addition to indirectly testing this based
on the resulting formatting.

ClangFormat does not correctly handle an Objective-C interface declaration
with both lightweight generics and a protocol conformance.
This simple example:
```
@interface Foo : Bar <Baz> <Blech>
@end
```
means `Foo` extends `Bar` (a lightweight generic class whose type
parameter is `Baz`) and also conforms to the protocol `Blech`.
ClangFormat should not apply any changes to the above example, but
instead it currently formats it quite poorly:
```
@interface Foo : Bar <Baz>
<Blech>
@end
```
The bug is that `UnwrappedLineParser` assumes an open-angle bracket
after a base class name is a protocol list, but it can also be a
lightweight generic specification.
This diff fixes the bug by factoring out the logic to parse
lightweight generics so it can apply both to the declared class
as well as the base class.

The argument passed to the preprocessor macros `NS_SWIFT_NAME(x)` and
`CF_SWIFT_NAME(x)` is stringified before passing to
`__attribute__((swift_name("x")))`.
ClangFormat didn't know about this stringification, so its custom parser
tried to parse the argument(s) passed to the macro as if they were
normal function arguments.
That means ClangFormat currently incorrectly inserts whitespace
between `NS_SWIFT_NAME` arguments with colons and dots, so:
```
extern UIWindow *MainWindow(void) NS_SWIFT_NAME(getter:MyHelper.mainWindow());
```
becomes:
```
extern UIWindow *MainWindow(void) NS_SWIFT_NAME(getter : MyHelper.mainWindow());
```
which clang treats as a parser error:
```
error: 'swift_name' attribute has invalid identifier for context name [-Werror,-Wswift-name-attribute]
```
Thankfully, D82620 recently added the ability to treat specific macros
as "whitespace sensitive", meaning their arguments are implicitly
treated as strings (so whitespace is not added anywhere inside).
This diff adds `NS_SWIFT_NAME` and `CF_SWIFT_NAME` to

Implementation details:
Let's look at a declaration with multiple declarators:

To generate a declarator list node we need to have the range of
declarators: `a, b`:
However, the `ClangAST` actually stores them as separate declarations:
`int a ;`
`int b;`
We solve that by appropriately marking the declarators on each separate
declaration in the `ClangAST` and then for the final declarator `int
b`, shrinking its range to fit to the already marked declarators.

Currently, when marshaling a dynamic AST matchers, we check for the type
and value validity of matcher arguments at the same time for some matchers.
For instance, when marshaling hasAttr("foo"), the argument is first type
checked to ensure it's a string and then checked to see if that string can
locate an attribute with that name. Similar happens for other enumeration
conversions like cast kinds or unary operator kinds. If the type is
correct but the value cannot be looked up, we make a best-effort attempt
to find a nearby name that the user might have meant, but if one cannot
be found, we throw our hands up and claim the types don't match.
This has an unfortunate behavior that when the user enters something of
the correct type but a best guess cannot be located, you get confusing
error messages like:
Incorrect type for arg 1. (Expected = string) != (Actual = String).
This patch splits the argument check into two parts: if the types don't
match, give a type diagnostic. If the type matches but the value cannot
be converted, give a best guess diagnostic or a value could not be
located diagnostic. This addresses PR47057.
There can be Macros that are tagged with `modifiable`. Thus verifying
`canModifyAllDescendants` is not sufficient to avoid macros when deep
copying.
We think the `TokenBuffer` could inform us whether a `Token` comes from
a macro. We'll look into that when we can surface this information
easily, for instance in unit tests for `ComputeReplacements`.

There are several `::IsStructurallyEquivalent` overloads for Decl subclasses
that are used for comparing declarations. There is also one overload that takes
just two Decl pointers which ends up queuing the passed Decls to be later
compared in `CheckKindSpecificEquivalence`.
`CheckKindSpecificEquivalence` implements the dispatch logic for the different
Decl subclasses. It is supposed to hand over the queued Decls to the
subclass-specific `::IsStructurallyEquivalent` overload that will actually
compare the Decl instance. It also seems to implement a few pieces of actual
node comparison logic inbetween the dispatch code.
This implementation causes that the different overloads of
`::IsStructurallyEquivalent` do different (and sometimes no) comparisons
depending on which overload of `::IsStructurallyEquivalent` ends up being
called.
For example, if I want to compare two FieldDecl instances, then I could either
call the `::IsStructurallyEquivalent` with `Decl *` or with `FieldDecl *`
parameters. The overload that takes FieldDecls is doing a correct comparison.
However, the `Decl *` overload just queues the Decl pair.
`CheckKindSpecificEquivalence` has no dispatch logic for `FieldDecl`, so it
always returns true and never does any actual comparison.
On the other hand, if I try to compare two FunctionDecl instances the two
possible overloads of `::IsStructurallyEquivalent` have the opposite behaviour:
The overload that takes `FunctionDecl` pointers isn't comparing the names of the
FunctionDecls while the overload taking a plain `Decl` ends up comparing the
function names (as the comparison logic for that is implemented in
`CheckKindSpecificEquivalence`).
This patch tries to make this set of functions more consistent by making
`CheckKindSpecificEquivalence` a pure dispatch function without any
subclass-specific comparison logic. Also the dispatch logic is now autogenerated
so it can no longer miss certain subclasses.
The comparison code from `CheckKindSpecificEquivalence` is moved to the
respective `::IsStructurallyEquivalent` overload so that the comparison result
no longer depends if one calls the `Decl *` overload or the overload for the
specific subclass. The only difference is now that the `Decl *` overload is
queuing the parameter while the subclass-specific overload is directly doing the
comparison.
`::IsStructurallyEquivalent` is an implementation detail and I don't think the
behaviour causes any bugs in the current implementation (as carefully calling
the right overload for the different classes works around the issue), so the
test for this change is that I added some new code for comparing `MemberExpr`.
The new comparison code always calls the dispatching overload and it previously
failed as the dispatch didn't support FieldDecls.

Right now the ASTImporter assumes for most Expr nodes that they are always equal

remaining subclasses in follow up patches (mostly because there are a lot of

The motivation for this is that in LLDB we try to import libc++ source code and
some of the types we are importing there contain expressions (e.g. because they
use `enable_if<expr>`), so those declarations are currently merged even if they
are completely different (e.g. `enable_if<value> ...` and `enable_if<!value>

Summary:
This is the first patch implementing the new Flang driver as outlined in [1],
[2] & [3]. It creates Flang driver (`flang-new`) and Flang frontend driver
(`flang-new -fc1`). These will be renamed as `flang` and `flang -fc1` once the
current Flang throwaway driver, `flang`, can be replaced with `flang-new`.
Currently only 2 options are supported: `-help` and `--version`.
`flang-new` is implemented in terms of libclangDriver, defaulting the driver
mode to `FlangMode` (added to libclangDriver in [4]). This ensures that the
driver runs in Flang mode regardless of the name of the binary inferred from
argv[0].
The design of the new Flang compiler and frontend drivers is inspired by it
counterparts in Clang [3]. Currently, the new Flang compiler and frontend
drivers re-use Clang libraries: clangBasic, clangDriver and clangFrontend.
To identify Flang options, this patch adds FlangOption/FC1Option enums.
Driver::printHelp is updated so that `flang-new` prints only Flang options.
The new Flang driver is disabled by default. To enable it, set
`-DBUILD_FLANG_NEW_DRIVER=ON` when configuring CMake and add clang to
`LLVM_ENABLE_PROJECTS` (e.g. -DLLVM_ENABLE_PROJECTS=“clang;flang;mlir”).

Decl::dump is primarily used for debugging to visualise the current state of a
declaration. Usually Decl::dump just displays the current state of the Decl and
doesn't actually change any of its state, however since commit
457226e02a the method actually started loading
additional declarations from the ExternalASTSource. This causes that calling
Decl::dump during a debugging session now actually does permanent changes to the
AST and will cause the debugged program run to deviate from the original run.
The change that caused this behaviour is the addition of
`hasConstexprDestructor` (which is called from the TextNodeDumper) which
performs a lookup into the current CXXRecordDecl to find the destructor. All
other similar methods just return their respective bit in the DefinitionData
(which obviously doesn't have such side effects).
This just changes the node printer to emit "unknown_constexpr" in case a
CXXRecordDecl is dumped that could potentially call into the ExternalASTSource
instead of the usually empty string/"constexpr". For CXXRecordDecls that can
safely be dumped the old behaviour is preserved

This adds a `AttributeMacros` configuration option that causes certain
identifiers to be parsed like a __attribute__((foo)) annotation.
This is motivated by our CHERI C/C++ fork which adds a __capability
qualifier for pointer/reference. Without this change clang-format parses
many type declarations as multiplications/bitwise-and instead.
I initially considered adding "__capability" as a new clang-format keyword,
but having a list of macros that should be treated as attributes is more
flexible since it can be used e.g. for static analyzer annotations or other language
extensions.

To achieve this we:

`NestedNameSpecifierLoc`s and automatically create its syntax nodes
* Add links from the `NestedNameSpecifierLoc`s to their syntax nodes.
In this way, from any semantic construct that has a `NestedNameSpecifier`,
we implicitly generate its syntax node via RAV and we can easily access
this syntax node via the links we added.

Summary:
This feature was only used in two places, but contributed a non-trivial
amount to the complexity of RecursiveASTVisitor, and was buggy (see my
recent patches where I was fixing the bugs that I noticed). I don't
think the convenience benefit of this feature is worth the complexity.
Besides complexity, another issue with the current state of
RecursiveASTVisitor is the non-uniformity in how it handles different
AST nodes. All AST nodes follow a regular pattern, but operators are
special -- and this special behavior not documented. Correct usage of
RecursiveASTVisitor relies on shadowing member functions with specific
names and signatures. Near misses don't cause any compile-time errors,
incorrectly named or typed methods are just silently ignored. Therefore,
predictability of RecursiveASTVisitor API is quite important.
This change reduces the size of the `clang` binary by 38 KB (0.2%) in
release mode, and by 7 MB (0.3%) in debug mode. The `clang-tidy` binary
is reduced by 205 KB (0.3%) in release mode, and by 5 MB (0.4%) in debug
mode. I don't think these code size improvements are significant enough
to justify this change on its own (for me, the primary motivation is
reducing code complexity), but they I think are a nice side-effect.

If you were around the analyzer for a while now, you must've seen a lot of
patches that awkwardly puts code from one library to the other:
* D75360 moves the constructors of CheckerManager, which lies in the Core
library, to the Frontend library. Most the patch itself was a struggle along
the library lines.
* D78126 had to be reverted because dependency information would be utilized
in the Core library, but the actual data lied in the frontend.
D78126#inline-751477 touches on this issue as well.
This stems from the often mentioned problem: the Frontend library depends on
Core and Checkers, Checkers depends on Core. The checker registry functions
(`registerMallocChecker`, etc) lie in the Checkers library in order to keep each
checker its own module. What this implies is that checker registration cannot
take place in the Core, but the Core might still want to use the data that
results from it (which checker/package is enabled, dependencies, etc).
D54436 was the patch that initiated this. Back in the days when CheckerRegistry
was super dumb and buggy, it implemented a non-documented solution to this
problem by keeping the data in the Core, and leaving the logic in the Frontend.
At the time when the patch landed, the merger to the Frontend made sense,
because the data hadn't been utilized anywhere, and the whole workaround without
any documentation made little sense to me.
So, lets put the data back where it belongs, in the Core library. This patch
introduces `CheckerRegistryData`, and turns `CheckerRegistry` into a short lived
wrapper around this data that implements the logic of checker registration. The
data is tied to CheckerManager because it is required to parse it.
Side note: I can't help but cringe at the fact how ridiculously awkward the
library lines are. I feel like I'm thinking too much inside the box, but I guess
this is just the price of keeping the checkers so modularized.

specifically, unary, binary, and compound assignment operators. In this
change I'm adding tests for operator AST nodes that follow the existing
pattern of tests for the CallExpr node (an AST node that triggers the
common code path).

In general there is no way to get to the ASTContext from most AST nodes
(Decls are one of the exception). This will be a problem when implementing
the rest of APValue::dump since we need the ASTContext to dump some kinds of
APValues.
The ASTContext* in ASTDumper and TextNodeDumper is not always
non-null. This is because we still want to be able to use the various
dump() functions in a debugger.
No functional changes intended.

Added new Macros `AST(_POLYMORPHIC)_MATCHER_REGEX(_OVERLOAD)` that define a matchers that take a regular expression string and optionally regular expression flags. This lets users match against nodes while ignoring the case without having to manually use `[Aa]` or `[A-Fa-f]` in their regex. The other point this addresses is in the current state, matchers that use regular expressions have to compile them for each node they try to match on, Now the regular expression is compiled once when you define the matcher and used for every node that it tries to match against. If there is an error while compiling the regular expression an error will be logged to stderr showing the bad regex string and the reason it couldn't be compiled. The old behaviour of this was down to the Matcher implementation and some would assert, whereas others just would never match. Support for this has been added to the documentation script as well. Support for this has been added to dynamic matchers ensuring functionality is the same between the 2 use cases.

Parent map of ASTContext is built once. If this happens and later
the TU is modified by getCrossTUDefinition the parent map does not
contain the newly imported objects and has to be re-created.
Invalidation of the parent map is added to the CrossTranslationUnitContext.
It could be added to ASTImporter as well but for now this task remains the
responsibility of the user of ASTImporter. Reason for this is mostly that
ASTImporter calls itself recursively.

FalsePositiveRefutationBRVisitor had a bug where the constraints were not
properly collected thus crosschecked with Z3.
This patch demonstratest and fixes that bug.
Bug:
The visitor wanted to collect all the constraints on a BugPath.
Since it is a visitor, it stated the visitation of the BugPath with the node
before the ErrorNode. As a final step, it visited the ErrorNode explicitly,
before it processed the collected constraints.
In principle, the ErrorNode should have visited before every other node.
Since the constraints were collected into a map, mapping each symbol to its
RangeSet, if the map already had a mapping with the symbol, then it was skipped.
This behavior was flawed if:
We already had a constraint on a symbol, but at the end in the ErrorNode we have
a tighter constraint on that. Therefore, this visitor would not utilize that
tighter constraint during the crosscheck validation.

When the c preprocessor stringizes tokens, the generated string literals
are affected by the whitespace. This means clang-format can affect
codegen silently, adding spaces and newlines to strings. Practically
speaking, the vast majority of cases will be harmless, only affecting
single identifiers or debug macros.
In the interest of doing no harm in other cases though, this introduces
a blacklist option 'WhitespaceSensitiveMacros', which contains a list of
names of function-like macros whose contents should not be touched by
clang-format, period. Clang-format can't automatically detect these
without a real compile context, so users will have to specify it
explicitly (it still beats clang-format off'ing at every invocation).
Defaults include "STRINGIZE", "PP_STRINGIZE", and "BOOST_PP_STRINGIZE".

Summary:
Previously, AST Matchers tests were using a custom way to run a test
with a specific C++ standard version. I'm migrating them to a shared
infrastructure to specify a Clang target from libClangTesting. I'm also
changing tests for AST Matchers to run in multiple language standards
versions, and under multiple triples that have different behavior with
regards to templates.
To keep the size of the patch manageable, in this patch I'm only
migrating one file to get the process started and get feedback on this
approach.
One caveat is that increasing the number of test configuration does
significantly increase the runtime of AST Matchers tests. On my machine,
the test runtime increases from 2.0 to 6.0s. I think it is worth the
improved test coverage.

Summary:
After D50078, we're experiencing unexpected un-indent using a style combining `AlignOperands: DontAlign` with `BreakBeforeTernaryOperators: false`, such as Google's JavaScript style:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;
```
The issue lies with the interaction of `AlignOperands: DontAlign` and the edited code section in ContinuationIndenter.cpp, which de-dents the intent by `Style.ContinuationIndentWidth`. From [[ ac3e5c4d93/clang/include/clang/Format/Format.h (L170) | the documentation ]] of AlignOperands: DontAlign:
> The wrapped lines are indented `ContinuationIndentWidth` spaces from the start of the line.
So the de-dent effectively erases the necessary `ContinuationIndentWidth` in that case.
This patch restores the `AlignOperands: DontAlign` behavior, producing:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :

outer levels as retained rather than omitting their arguments.
This better reflects what's going on (we're performing a substitution
while still inside a template), and in theory is more correct, but I've
not found a testcase where it matters in practice (largely because we
don't allow alias templates to be declared inside a function).
Fixed AST dumping of SubstNonTypeTemplateParm[Pack]Expr to demonstrate
that we're properly substituting through dependent alias templates. (We
can't deduce properly through these yet, but we can at least produce the
right input to template argument deduction.)
No functionality change intended.
Currently, using the nullPointerConstant AST matcher can lead to
assertions in situations where a node to be matched does not have a
valid type associated with it, such as a ParenListExpr. This patch
addresses that by saying such nodes cannot be a null pointer constant.
This addresses PR46353.
Summary:
In ASTMatcher, when we have `has(...)` and `hasParent(...)` called with the same internal matcher on the same node, the memoization process will mix-up the two calls because the direction of the traversal is not part of the memoization key.
This patch adds this information.

When clang-format is run with option AllowShortBlocksOnASingleLine, it is expected to either succeed in putting the short block with its control statement on a single line or fail and leave the block as is. When brace wrapping after control statement is activated, if the block + the control statement length is superior to column limit but the block alone is not, clang-format puts the block in two lines: one for the control statement and one for the block. This patch removes this unexpected behaviour. Current unittests are updated to check for this behaviour.

Checker dependencies were added D54438 to solve a bug where the checker names
were incorrectly registered, for example, InnerPointerChecker would incorrectly
emit diagnostics under the name MallocChecker, or vice versa [1]. Since the
system over the course of about a year matured, our expectations of what a role
of a dependency and a dependent checker should be crystallized a bit more --
D77474 and its summary, as well as a variety of patches in the stack
demonstrates how we try to keep dependencies to play a purely modeling role. In
fact, D78126 outright forbids diagnostics under a dependency checkers name.
These dependencies ensured the registration order and enabling only when all
dependencies are satisfied. This was a very "strong" contract however, that
doesn't fit the dependency added in D79420. As its summary suggests, this
relation is directly in between diagnostics, not modeling -- we'd prefer a more
specific warning over a general one.
To support this, I added a new dependency kind, weak dependencies. These are not
as strict of a contract, they only express a preference in registration order.
If a weak dependency isn't satisfied, the checker may still be enabled, but if
it is, checker registration, and transitively, checker callback evaluation order
is ensured.
If you are not familiar with the TableGen changes, a rather short description
can be found in the summary of D75360. A lengthier one is in D58065.

Retrieving the parameter location of functions was disabled because it
may causes crashes due to the fact that functions may have multiple
declarations and without definition it is difficult to ensure that
always the same declration is used. Now parameters are stored in
`ParamRegions` which are independent of the declaration of the function,
therefore the same parameters always have the same regions,
independently of the function declaration used actually. This allows us
to remove the limitation described above.
Differential Revision: https://reviews.llvm.org/D80286
Currently, parameters of functions without their definition present cannot
be represented as regions because it would be difficult to ensure that the
same declaration is used in every case. To overcome this, we split
`VarRegion` to two subclasses: `NonParamVarRegion` and `ParamVarRegion`.
The latter does not store the `Decl` of the parameter variable. Instead it
stores the index of the parameter which enables retrieving the actual
`Decl` every time using the function declaration of the stack frame. To
achieve this we also removed storing of `Decl` from `DeclRegion` and made
`getDecl()` pure virtual. The individual `Decl`s are stored in the
appropriate subclasses, such as `FieldRegion`, `ObjCIvarRegion` and the
newly introduced `NonParamVarRegion`.

If you are in the middle of editing and somehow you've missed a { or } in your code, somewhere, often way below where you are at the bottom of your file the namespace comment fixer will have put the namespace on the previous closing brace.
This leads to you having to fix up the bottom of the file.

Summary:
The following revision follows D80115 since @MyDeveloperDay and I apparently both had the same idea at the same time, for https://bugs.llvm.org/show_bug.cgi?id=45816 and my efforts on tooling support for AMDVLK, respectively.
This option aligns adjacent bitfield separators across lines, in a manner similar to AlignConsecutiveAssignments and friends.
Example:
```
struct RawFloat {
uint32_t sign : 1;
uint32_t exponent : 8;
uint32_t mantissa : 23;
};
```
would become
```
struct RawFloat {
uint32_t sign : 1;
uint32_t exponent : 8;
uint32_t mantissa : 23;
};
```
This also handles c++2a style bitfield-initializers with AlignConsecutiveAssignments.
```
struct RawFloat {
uint32_t sign : 1 = 0;
uint32_t exponent : 8 = 127;
uint32_t mantissa : 23 = 0;
}; // defaults to 1.0f
```
Things this change does not do:
- Align multiple comma-chained bitfield variables. None of the other
AlignConsecutive* options seem to implement that either.
- Detect bitfields that have a width specified with something other
than a numeric literal (ie, `int a : SOME_MACRO;`). That'd be fairly
difficult to parse and is rare.

When a '//comment' trails a consecutive alignment, it adds a whitespace
replacement within the comment token. This wasn't handled correctly in
the alignment code, which treats it as a whole token and thus double
counts it.
This can wrongly trigger the "line too long, it'll wrap" alignment-break
condition with specific lengths, causing the alignment to break for
seemingly no reason.

With Chromium style (although that is not important) its just it defines PointerAligmment: Left
The following arguments `S&&` are formatted differently depending on if the class has an attribute between it and the class identifier
```
class S {
S(S&&) = default;
};
class [[nodiscard]] S {
S(S &&) = default;
};
```
The prescense of [[nodiscard]] between the `class/struct` and the `{` causes the `{` to be incorrectly seen as a `TT_FunctionLBrace` which in turn transforms all the && to be `TT_BinaryOperators` rather than `TT_PointerOrReference`, as binary operators other spacing rules come into play causing a miss format

One of the pain points in simplifying MallocCheckers interface by gradually
changing to CallEvent is that a variety of C++ allocation and deallocation
functionalities are modeled through preStmt<...> where CallEvent is unavailable,
and a single one of these callbacks can prevent a mass parameter change.
This patch introduces a new CallEvent, CXXDeallocatorCall, which happens after
preStmt<CXXDeleteExpr>, and can completely replace that callback as

Summary:
When multiple ternary operators are chained, e.g. like an if/else-if/
else-if/.../else sequence, clang-format will keep aligning the colon
with the question mark, which increases the indent for each
conditionals:
int a = condition1 ? result1
: condition2 ? result2
: condition3 ? result3
: result4;
This patch detects the situation (e.g. conditionals used in false branch
of another conditional), to avoid indenting in that case:
int a = condition1 ? result1
: condition2 ? result2
: condition3 ? result3
: result4;
When BreakBeforeTernaryOperators is false, this will format like this:
int a = condition1 ? result1 :
condition2 ? result2 :
conditino3 ? result3 :
result4;

The commit 3c28a2dc6b introduced the check that checks if we're
trying to re-enter a main file when building a preamble. Unfortunately this slowed down the preamble
compilation by 80-90% in some test cases, as translateFile is really slow. This change checks
to see if the FileEntry is the main file without calling translateFile, but by using the new
isMainFile check instead. This speeds up preamble building by 1.5-2x for certain test cases that we have.

Summary:
Currently the 'AlignConsecutive*' options incorrectly align across
elif and else statements, even if they are very far away and across
unrelated preprocessor macros.
This failed since on preprocessor run 2+, there is not enough context
about the #ifdefs to actually differentiate one block from another,
causing them to align across different blocks or even large sections of
the file.
Eg, with AlignConsecutiveAssignments:
```
\#if FOO // Run 1
\#else // Run 1
int a = 1; // Run 2, wrong
\#endif // Run 1
\#if FOO // Run 1
\#else // Run 1
int bar = 1; // Run 2
\#endif // Run 1
```
is read as
```
int a = 1; // Run 2, wrong
int bar = 1; // Run 2
```
The approach taken to fix this was to add a new flag to Token that
forces breaking alignment across groups of lines (MustBreakAlignBefore)
in a similar manner to the existing flag that forces a line break
(MustBreakBefore). This flag is set for the first Token after a
preprocessor statement or diff conflict marker.

Summary: systemd recently added a clang-format file. One issue I
encountered in using clang-format on systemd is that systemd does
not add a space before the parens of their foreach macros but
clang-format always adds a space. This does not seem to be
configurable in clang-format. This revision adds the
ControlStatementsExceptForEachMacros option to SpaceBeforeParens
which puts a space before all control statement parens except
ForEach macros. This drastically reduces the amount of changes
when running clang-format on systemd's source code.

Ensure the clang-format unit tests are themselves clang-formatted
Having areas of the llvm code which are clang-format clean, give us more areas to run new clang-format binaries on ensuring we haven't broken anything.
It seems to me we SHOULD have this clang-formatted at a minimum, otherwise how can we expect others to use clang-format if we "don't eat our own dogfood", also if the tests are dependent on the formatting of the code then that would also be bad!

Summary: The condition added with the new setting checked whether the character was an l-brace, not specifically a lambda l-brace, when deciding whether it was possible to break before it or not. This caused the l-brace of some initialiser lists to break onto the next line with the first argument of the initialiser list when the setting was enabled.

As a result of that any file ID created for an include inside the

SourceManager::computeMacroArgsCache.
To fix this issue we first record number of created FIDs for predefined
