Move the listing of allowed clauses per OpenMP directive to the new
macro file in `llvm/Frontend/OpenMP`. Also, use a single generic macro
that specifies the directive and one allowed clause explicitly instead
of a dedicated macro per directive.
We save 800 loc and boilerplate for all new directives/clauses with no
functional change. We also need to include the macro file only once and
not once per directive.

Differential Revision: https://reviews.llvm.org/D77112
Summary:
This patch removes delayed folding and replaces it with forward peeking.
Delayed folding was previously used as a solution to the problem that
declaration doesn't have a representation in the AST. For example following
code:
```
int a,b;
```
is expressed in the AST as:
```
TranslationUnitDecl
|-...
|-VarDecl `int a`
`-VarDecl `int b`
```
And in the syntax tree we need:
```
*: TranslationUnit
`-SimpleDeclaration
|-int
|-SimpleDeclarator
| `-a
|-,
|-SimpleDeclarator
| `-b
|-;
```
So in words, we need to create SimpleDeclaration to be a parent of
SimpleDeclarator nodes. Previously we used delayed folding to make sure SimpleDeclarations will be
eventually created. And in case multiple declarators requested declaration
creation, declaration range was extended to cover all declarators.
This design started to be hard to reason about, so we decided to replace it with
forward peeking. The last declarator node in the chain is responsible for creating
SimpleDeclaration for the whole chain. Range of the declaration corresponds to
the source range of the declarator node. Declarator decides whether its the last
one by peeking to the next AST node (see `isResponsibleForCreatingDeclaration`).
This patch does following:
* Removed delayed folding logic
* Tweaks Token.dumpForTests
* Moves getQualifiedNameStart inside BuildTreeVisitor
* Extracts BuildTreeVisitor.ProcessDeclaratorAndDeclaration
* Renames Builder.getDeclRange to Builder.getDeclarationRange and uses the
method in all places.
* Adds a bunch of tests

This fixes a regression from D69573 which broke the following example:

It seems the problem is in TokenAnnotator::spaceRequiredBetween(),

`CheckerRegistry` registers a checker either if it is excplicitly
enabled or it is a dependency of an explicitly enabled checker and is
not explicitly disabled. In both cases it is also important that the

Currently there is a bug here: if the dependenct checker is not

One of the defining features of the SVE ACLE types is that they
are "sizeless"; see the SVE ACLE spec:
https://developer.arm.com/docs/100987/0000/arm-c-language-extensions-for-sve
or the email message:
http://lists.llvm.org/pipermail/cfe-dev/2019-June/062523.html
for a fuller definition of what that means.
This patch adds two associated type queries:
- isSizelessBuiltinType asks specifically about types that are built
into clang. It is effectively an enum range check.
- isSizelessType instead tests for any type that has the "sizeless" type
property. At the moment it only returns true for the built-in types,
but it seems better not to hard-code that assumption throughout
the codebase. (E.g. we could in principle support some form of
user-defined sizeless types in future. Even if that seems unlikely
and never actually happens, the possibility at least exists.)

Most clients of SourceManager.h need to do things like turning source
locations into file & line number pairs, but this doesn't require
bringing in FileManager.h and LLVM's FS headers.
The main code change here is to sink SM::createFileID into the cpp file.
I reason that this is not performance critical because it doesn't happen
on the diagnostic path, it happens along the paths of macro expansion
(could be hot) and new includes (less hot).

Summary:
When importing the main FileID the ASTImporter currently gives it no include location. This means
that any SourceLocations produced for this FileID look to Clang as if they are coming from the
main FileID (as the main FileID has no include location).
Clang seems to expect that there is only one main FileID in one translation unit (which makes sense
during normal compilation), so this behavior leads to several problems when producing diagnostics,
one being that when calling `SourceManager::isBeforeInTranslationUnit` on two SourceLocations
that come from two different ASTContext instances, Clang fails to sort the SourceLocations as
the include chains of the FileIDs don't end up in a single FileID. This causes that Clang crashes
with "Unsortable locations found" in this function.
This patch gives any imported main FileIDs the main FileID of the To ASTContext as its include
location. This allows Clang to sort all imported SourceLocations as now all include chains point
to the main FileID of the To ASTContext. The exact include location is currently set to the start
of the To main file (just because that should always be a valid SourceLocation).

Summary:
This change adds an option to insert trailing commas into container
literals. For example, in JavaScript:
const x = [
a,
b,
^~~~~ inserted if missing.
]
This is implemented as a seperate post-processing pass after formatting
(because formatting might change whether the container literal does or
does not wrap). This keeps the code relatively simple and orthogonal,
though it has the notable drawback that the newly inserted comma is not
taken into account for formatting decisions (e.g. it might exceed the 80
char limit). To avoid exceeding the ColumnLimit, a comma is only
inserted if it fits into the limit.
Trailing comma insertion conceptually conflicts with argument
bin-packing: inserting a comma disables bin-packing, so we cannot do
both. clang-format rejects FormatStyle configurations that do both with
this change.

Differential Revision: https://reviews.llvm.org/D72144
Summary:
clang-format currently treats the nullish coalescing operator `??` like
the ternary operator. That causes multiple nullish terms to be each
indented relative to the last `??`, as they would in a ternary.
The `??` operator is often used in chains though, and as such more
similar to other binary operators, such as `||`. So to fix the indent,
set its token type to `||`, so it inherits the same treatment.
This opens up the question of operator precedence. However, `??` is
required to be parenthesized when mixed with `||` and `&&`, so this is
not a problem that can come up in syntactically legal code.

Summary:
The documentation for IndentCaseLabels claimed that the "Switch
statement body is always indented one level more than case labels". This
is technically false for the code block immediately following the label.
Its closing bracket aligns with the start of the label.
If the case label are not indented, it leads to a style where the
closing bracket of the block aligns with the closing bracket of the
switch statement, which can be hard to parse.
This change introduces a new option, IndentCaseBlocks, which when true
treats the block as a scope block (which it technically is).

Partially reverts 0a2be46cfd as it turned
out to cause redundant module rebuilds in multi-process incremental builds.
When a module was getting out of date, all compilation processes started at the
same time were marking it as `ToBuild`. So each process was building the same
module instead of checking if it was built by someone else and using that
result. In addition to the work duplication, contention on the same .pcm file
wasn't making builds faster.
Note that for a single-process build this change would cause redundant module
reads and validations. But reading a module is faster than building it and
multi-process builds are more common than single-process. So I'm willing to
make such a trade-off.

Summary:
This patch could be treated as a rebase of D33960. It also fixes PR35547.
A fix for `llvm/test/Other/close-stderr.ll` is proposed in D68164. Seems
the consensus is that the test is passing by chance and I'm not
sure how important it is for us. So it is removed like in D33960 for now.
The rest of the test fixes are just adding `--crash` flag to `not` tool.
** The reason it fixes PR35547 is
`exit` does cleanup including calling class destructor whereas `abort`
does not do any cleanup. In multithreading environment such as ThinLTO or JIT,
threads may share states which mostly are ManagedStatic<>. If faulting thread
tearing down a class when another thread is using it, there are chances of
memory corruption. This is bad 1. It will stop error reporting like pretty
stack printer; 2. The memory corruption is distracting and nondeterministic in
terms of error message, and corruption type (depending one the timing, it
could be double free, heap free after use, etc.).

This is both more efficient and avoids corner cases in
`SourceManager::isBeforeInTranslationUnit`.
The change is trivial and clearly a performance improvement on the hot
path of building the syntax tree, so sending without review.
Summary:
This patch adds facilities to mutate the syntax trees and produce
corresponding text replacements.
The public interface of the syntax library now includes facilities to:
1. perform type-safe modifications of syntax trees,
2. compute textual replacements to apply the modifications,
3. create syntax trees not backed by the source code.
For each of the three, we only add a few example transformations in this
patch to illustrate the idea, support for more kinds of nodes and
transformations will be done in follow-up patches.
The high-level mutation operations are implemented on top of operations
that allow to arbitrarily change the trees. They are considered to be
implementation details and are not available to the users of the
library.

Patch by Jonathan Thomas (jonathoma)!
Summary:
The exclusive-claim model is successful at resolving conflicts over tokens
between parent/child or siblings. However claims at the spelled-token
level do the wrong thing for macro expansions, where siblings can be
equally associated with the macro invocation.
Moreover, any model that only uses the endpoints in a range can fail when
a macro invocation occurs inside the node.
To address this, we use the existing TokenBuffer in more depth.
Claims are expressed in terms of expanded tokens, so there is no need to worry
about macros, includes etc.
Once we know which expanded tokens were claimed, they are mapped onto
spelled tokens for hit-testing.
This mapping is fairly flexible, currently the handling of macros is
pretty simple (map macro args onto spellings, other macro expansions onto the
macro name token).
This mapping is in principle token-by-token for correctness (though
there's some batching for performance).
The aggregation of the selection enum is now more principled as we need to be
able to aggregate several hit-test results together.
For simplicity i removed the ability to determine selectedness of TUDecl.
(That was originally implemented in 90a5bf92ff97b1, but doesn't seem to be very
important or worth the complexity any longer).
The expandedTokens(SourceLocation) helper could be added locally, but seems to
make sense on TokenBuffer.

Summary:
Currently, stencils are defined as a sequence of `StencilParts`. This
differentiation adds an unneeded layer of complexity to the definition of
Stencils. This change significantly simplifies the type structure: a stencil is
now conceptually any object implementing `StencilInterface` and `Stencil` is
just a thin wrapper for pointers to this interface.
To account for the sequencing that was supported by the old `Stencil` type, we
introduce a sequencing class that implements `StencilInterface`. That is,
sequences are just another kind of Stencil and no longer have any special
status.
Corresponding to this change in the type structure, we change the way `cat` is
used (and defined). `cat` bundles multiple features: it builds a stencil from a
sequence of subcomponents and admits multiple different types for its arguments,
while coercing them into the right type. Previously, `cat` was also used to
coerce a single `StencilPart` into a `Stencil`. With that distinction gone, many
uses of `cat` (e.g. in the tests) are unnecessary and have, therefore, been
removed.

Summary:
r373922 added checks for a few tokens that, following an `)` make it
unlikely that the `)` is the closing paren of a cast expression. The
specific check for `tok::l_square` there introduced a regression for
casts of Obj-C calls, like:
```
(cast)[func arg]
```
From the tests added in r373922, I believe the `tok::l_square` case is added to
capture the case where a non-cast `)` is directly followed by an
attribute specifier, like:
```
int f(int x) [[noreturn]];
```
I've specialized the code to look for such attribute specifier instead
of `tok::l_square` in general. Also, I added a regression test and moved
the test cases added in r373922 to an already existing place documenting
other instances of historically misidentified casts.

Summary:
Removes the `isEqual` method from StencilPartInterface and modifies equality to
use the string representation returned by the `toString` method for comparison.
This means the `run` and `selection` stencils return true by default, and
clients should be cautious in relying on equality operator for comparison of
stencils containing parts generated by these functions.
It also means we no longer need the custom RTTI support (typeId() and
down_cast()), so it has been removed.

llvm-svn: 374271
Summary:
r373165 fixed an issue where a templated noexcept member function with a
reference qualifier would be indented more than expected:
```
// Formatting produced with LLVM style with AlwaysBreakTemplateDeclarations: Yes
// before r373165:
struct f {
template <class T>
void bar() && noexcept {}
};
// after:
struct f {
template <class T>
void bar() && noexcept {}
};
```
The way this is done is that in the AnnotatingParser in
`lib/FormatTokenAnnotator.cpp` the determination of the usage of a `&` or `&&`
(the line in determineTokenType
```
Current.Type = determineStarAmpUsage(...
```
is not performed in some cases anymore, combining with a few additional related
checks afterwards. The net effect of these checks results in the `&` or `&&`
token to start being classified as `TT_Unknown` in cases where before `r373165`
it would be classified as `TT_UnaryOperator` or `TT_PointerOrReference` by
`determineStarAmpUsage`.
This inadvertently caused 2 classes of regressions I'm aware of:
- The address-of `&` after a function assignment would be classified as
`TT_Unknown`, causing spaces to surround it, disregarding style options:
```
// before r373165:
void (*fun_ptr)(void) = &fun;
// after:
void (*fun_ptr)(void) = & fun;
```
- In cases where there is a function declaration list -- looking macro between
a template line and the start of the function declaration, an `&` as part of
the return type would be classified as `TT_Unknown`, causing spaces to
surround it:
```
// before r373165:
template <class T>
DEPRECATED("lala")
Type& foo();
// after:
template <class T>
DEPRECATED("lala")
Type & foo();
```
In these cases the problems are rooted in the skipping of the classification of
a `&` (and similarly `&&`) by determineStarAmpUsage which effects the formatting
decisions later in the pipeline.
I've looked into the goal of r373165 and noticed that replacing `noexcept` with
`const` in the given example produces no extra indentation with the old code:
```
// before r373165:
struct f {
template <class T>
int foo() & const {}
};
struct f {
template <class T>
int foo() & noexcept {}
};
```
I investigated how clang-format annotated these two examples differently to
determine the places where the processing of both diverges in the pipeline.
There were two places where the processing diverges, causing the extra indent in
the `noexcept` case:
1. The `const` is annotated as a `TT_TrailingAnnotation`, whereas `noexcept`
is annotated as `TT_Unknown`. I've updated the `determineTokenType` function
to account for this by adding a missing `tok:kw_noexcept` to the clause that
marks a token as `TT_TrailingAnnotation`.
2. The `&` in the second example is wrongly identified as `TT_BinaryOperator`
in `determineStarAmpUsage`. This is the reason for the extra indentation --
clang-format gets confused and thinks this is an expression.
I've updated `determineStarAmpUsage` to check for `tok:kw_noexcept`.
With these two updates in place, the additional parsing introduced by r373165
becomes unnecessary and all added tests pass (with updates, as now clang-format
respects the style configuration for spaces around the `&` in the test
examples).
I've removed these additions and added regression tests for the cases above.

The existing string/character literal skipping code in the
dependency directives source minimizer has two issues:
- It doesn't stop the scanning when a newline is reached before the terminating character,
unlike the lexer which considers the token to be done (even if it's invalid) at the end of the line.
- It doesn't support whitespace between '\' and the newline when looking if the '\' is used as a line continuation character.
This commit fixes both issues.

Summary:
Change the BraceWrappingFlags' AfterControlStatement from a bool to an enum with three values:
* "Never": This is the default, and does not do any brace wrapping after control statements.
* "MultiLine": This only wraps braces after multi-line control statements (this really only happens when a ColumnLimit is specified).
* "Always": This always wraps braces after control statements.
The first and last options are backwards-compatible with "false" and "true", respectively.
The new "MultiLine" option is useful for when a wrapped control statement's indentation matches the subsequent block's indentation. It makes it easier to see at a glance where the control statement ends and where the block's code begins. For example:
```
if (
foo
&& bar )
{
baz();
}
```
vs.
```
if (
foo
&& bar ) {
baz();
}
```
Short control statements (1 line) do not wrap the brace to the next line, e.g.
```
if (foo) {
bar();
} else {
baz();
}

Summary:
The historical context:
- clang-format was written when C++11 was current,
and the main language-version concern was >> vs > > template-closers.
An option was added to allow selection of the 03/11 behavior, or auto-detection.
- there was no option to choose simply "latest standard" so anyone who didn't
ever want 03 behavior or auto-detection specified Cpp11.
- In r185149 this option started to affect lexer mode.
- no options were added to cover c++14, as parsing/formatting
didn't change that much. The usage of Cpp11 to mean "latest" became
codified e.g. in r206263
- c++17 added some new constructs. These were mostly backwards-compatible and so
not used in old programs, so having no way to turn them off was OK.
- c++20 added some new constructs and keywords (e.g. co_*) that changed the
meaning of existing programs, and people started to complain that
the c++20 parsing couldn't be turned off.
New plan:
- Default ('Auto') behavior remains unchanged: parse as latest, format
template-closers based on input.
- Add new 'Latest' option that more clearly expresses the intent "use
modern features" that many projects have chosen for their .clang-format files.
- Allow pinning to *any* language version, using the same name as clang -std:
c++03, c++11, c++14 etc. These set precise lexer options, and any
clang-format code depending on these can use a >= check.
- For backwards compatibility, `Cpp11` is an alias for `Latest`, not `c++11`.
This matches the historical documented semantics of this option.
This spelling (and `Cpp03`) are deprecated.

Summary:
This is a patch to fix PR43372 (https://bugs.llvm.org/show_bug.cgi?id=43372) - clang-format can't format file with includes, ( which really keep providing replacements for already sorted headers.)
A similar issue was addressed by @krasimir in {D60199}, however, this seemingly only prevented the issue when the files being formatted did not contain windows line endings (\r\n)
It's possible this is related to https://twitter.com/StephanTLavavej/status/1176722938243895296 given who @STL_MSFT works for!
As people often used the existence of replacements to determine if a file needs clang-formatting, this is probably pretty important for windows users
There may be a better way of comparing 2 strings and ignoring \r (which appear in both Results and Code), I couldn't choose between this idiom or the copy_if approach, but I'm happy to change it to whatever people consider more performant.
