[lldb] Reland: Store SupportFile in FileEntry (NFC) (#85892)
This is another step towards supporting DWARF5 checksums and inline
source code in LLDB. This is a reland of #85468 but without the
functional change of storing the support file from the line table (yet).

[lldb] Refactor GetFormatFromCString to always check for partial matches (NFC) (#81018)
Refactors logic in `ParseInternal` that was previously calling
`GetFormatFromCString` twice, once with `partial_match_ok` set to false,
and the second time set to true.

With this change, lldb formats (ie `%@`, `%S`, etc) are checked first.
If a format is not one of those, then `GetFormatFromCString` is called
once, and now always checks for partial matches.

1370a1cb5b [lldb] Add support for negative integer to {SB,}StructuredData
This patch refactors the `StructuredData::Integer` class to make it
templated, makes it private and adds 2 public specialization for both
`int64_t` & `uint64_t` with a public type aliases, respectively
`SignedInteger` & `UnsignedInteger`.

It adds new getter for signed and unsigned interger values to the
`StructuredData::Object` base class and changes the implementation of
`StructuredData::Array::GetItemAtIndexAsInteger` and
`StructuredData::Dictionary::GetValueForKeyAsInteger` to support signed
and unsigned integers.

This patch also adds 2 new `Get{Signed,Unsigned}IntegerValue` to the
`SBStructuredData` class and marks `GetIntegerValue` as deprecated.

Finally, this patch audits all the caller of `StructuredData::Integer`
or `StructuredData::GetIntegerValue` to use the proper type as well the
various tests that uses `SBStructuredData.GetIntegerValue`.

c34698a811 [lldb] Rename Logging.h to LLDBLog.h and clean up includes
Most of our code was including Log.h even though that is not where the
"lldb" log channel is defined (Log.h defines the generic logging
infrastructure). This worked because Log.h included Logging.h, even
though it should.

After the recent refactor, it became impossible the two files include
each other in this direction (the opposite inclusion is needed), so this
patch removes the workaround that was put in place and cleans up all
files to include the right thing. It also renames the file to LLDBLog to
better reflect its purpose.

363f05b83d [lldb] Delete the SharingPtr class
Summary:
The only use of this class was to implement the SharedCluster of ValueObjects.
However, the same functionality can be implemented using a regular
std::shared_ptr, and its little-known "sub-object pointer" feature, where the
pointer can point to one thing, but actually delete something else when it goes
out of scope.

This patch reimplements SharedCluster using this feature --
SharedClusterPointer::GetObject now returns a std::shared_pointer which points
to the ValueObject, but actually owns the whole cluster. The only change I
needed to make here is that now the SharedCluster object needs to be created
before the root ValueObject. This means that all private ValueObject
constructors get a ClusterManager argument, and their static Create functions do
the create-a-manager-and-pass-it-to-value-object dance.

To do so, the StackFrameRecognizer class holds a "Most Relevant Frame" and a

if the current frame is recognized, and if so, it fetches the recognized frame's

808142876c [lldb][NFC] Fix all formatting errors in .cpp file headers
Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Summary:
CompileUnit is a complicated class. Having it be implicitly convertible
to a FileSpec makes reasoning about it even harder.

This patch replaces the inheritance by a simple member and an accessor
function. This avoid the need for casting in places where one needed to
force a CompileUnit to be treated as a FileSpec, and does not add much
verbosity elsewhere.

It also fixes a bug where we were wrongly comparing CompileUnit& and a
CompileUnit*, which compiled due to a combination of this inheritance
and the FileSpec*->FileSpec implicit constructor.

ae34ed2c0d [lldb][NFC] Remove WordComplete mode, make result array indexed from 0 and remove any undocumented/redundant return values
Summary:
We still have some leftovers of the old completion API in the internals of
LLDB that haven't been replaced by the new CompletionRequest. These leftovers
are:

* The return values (int/size_t) in all completion functions.
* Our result array that starts indexing at 1.
* `WordComplete` mode.

I didn't replace them back then because it's tricky to figure out what exactly they
are used for and the completion code is relatively untested. I finally got around
to writing more tests for the API and understanding the semantics, so I think it's
a good time to get rid of them.

A few words why those things should be removed/replaced:

* The return values are really cryptic, partly redundant and rarely documented.
  They are also completely ignored by Xcode, so whatever information they contain will end up
  breaking Xcode's completion mechanism. They are also partly impossible to even implement
  as we assign negative values special meaning and our completion API sometimes returns size_t.

  Completion functions are supposed to return -2 to rewrite the current line. We seem to use this
  in some untested code path to expand the history repeat character to the full command, but
  I haven't figured out why that doesn't work at the moment.
  Completion functions return -1 to 'insert the completion character', but that isn't implemented
  (even though we seem to activate this feature in LLDB sometimes).
  All positive values have to match the number of results. This is obviously just redundant information
  as the user can just look at the result list to get that information (which is what Xcode does).

* The result array that starts indexing at 1 is obviously unexpected. The first element of the array is
  reserved for the common prefix of all completions (e.g. "foobar" and "footar" -> "foo"). The idea is
  that we calculate this to make the life of the API caller easier, but obviously forcing people to have
  1-based indices is not helpful (or even worse, forces them to manually copy the results to make it
  0-based like Xcode has to do).

* The `WordComplete` mode indicates that LLDB should enter a space behind the completion. The
  idea is that we let the top-level API know that we just provided a full completion. Interestingly we
  `WordComplete` is just a single bool that somehow represents all N completions. And we always
  provide full completions in LLDB, so in theory it should always be true.
  The only use it currently serves is providing redundant information about whether we have a single
  definitive completion or not (which we already know from the number of results we get).

This patch essentially removes `WordComplete` mode and makes the result array indexed from 0.
It also removes all return values from all internal completion functions. The only non-redundant information
they contain is about rewriting the current line (which is broken), so that functionality was moved
to the CompletionRequest API. So you can now do `addCompletion("blub", "description", CompletionMode::RewriteLine)`
to do the same.

For the SB API we emulate the old behaviour by making the array indexed from 1 again with the common
prefix at index 0. I didn't keep the special negative return codes as we either never sent them before (e.g. -2) or we
didn't even implement them in the Editline handler (e.g. -1).

I tried to keep this patch minimal and I'm aware we can probably now even further simplify a bunch of related code,
but I would prefer doing this in follow-up NFC commits

2b29b432d2 [ScriptInterpreter] Move ownership into debugger (NFC)
This is part two of the change started in r359330. This patch moves the
ownership of the script interpreter from the command interpreter into
the debugger. I would've preferred to remove the lazy initialization,
however the fact that the scripting language is set after the debugger
is created makes that tricky. So for now this does exactly the same
thing as when it was under the command interpreter. The result is that
this patch is fully NFC.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
