Shafik Yaghmour 28c878aeb2 [LLDB] Applying clang-tidy modernize-use-default-member-init over LLDB
Applied modernize-use-default-member-init clang-tidy check over LLDB.
It appears in many files we had already switched to in class member init but
never updated the constructors to reflect that. This check is already present in
the lldb/.clang-tidy config.

Michał Górny 14735cab65 [lldb] [gdb-remote] Add eOpenOptionReadWrite for future gdb compat
Modify OpenOptions enum to open the future path into synchronizing
vFile:open bits with GDB.  Currently, LLDB and GDB use different flag
models effectively making it impossible to match bits.  Notably, LLDB
uses two bits to indicate read and write status, and uses union of both
for read/write.  GDB uses a value of 0 for read-only, 1 for write-only
and 2 for read/write.

In order to future-proof the code for the GDB variant:

1. Add a distinct eOpenOptionReadWrite constant to be used instead
   of (eOpenOptionRead | eOpenOptionWrite) when R/W access is required.

2. Rename eOpenOptionRead and eOpenOptionWrite to eOpenOptionReadOnly
   and eOpenOptionWriteOnly respectively, to make it clear that they
   do not mean to be combined and require update to all call sites.

3. Use the intersection of all three flags when matching against
   the three possible values.

This commit does not change the actual bits used by LLDB.

Jonas Devlieghere d144087c96 [lldb/Support] Treat empty FileSpec as an invalid file.
LLDB relies on empty FileSpecs being invalid files, for example, they
don't exists. Currently this assumption does not always hold during
reproducer replay, because we pass the result of GetPath to the VFS.
This is an empty string, which the VFS converts to an absolute directory
by prepending the current working directory, before looking it up in the
YAML mapping. This means that an empty FileSpec will exist when the
current working directory does. This breaks at least one test
(TestAddDsymCommand.py) when ran from replay.

This patch special cases empty FileSpecs and returns a sensible result
before calling GetPath and forwarding the call.

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Raphael Isemann 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).

Lawrence D'Anna 2fce1137c7 Convert FileSystem::Open() to return Expected<FileUP>
Summary:
This patch converts FileSystem::Open from this prototype:

Status
Open(File &File, const FileSpec &file_spec, ...);

to this one:

llvm::Expected<std::unique_ptr<File>>
Open(const FileSpec &file_spec, ...);

This is beneficial on its own, as llvm::Expected is a more modern
and recommended error type than Status.  It is also a necessary step
towards https://reviews.llvm.org/D67891, and further developments
for lldb_private::File.

Chandler Carruth 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.

On Windows, when using the VFS without going through FileSpec, the

Jonas Devlieghere 46376966ea [FileSystem] Extend file system and have it use the VFS.
This patch extends the FileSystem class with a bunch of functions that
are currently implemented as methods of the FileSpec class. These
methods will be removed in future commits and replaced by calls to the
file system.

The new functions are operated in terms of the virtual file system which
was recently moved from clang into LLVM so it could be reused in lldb.
Because the VFS is stateful, we turned the FileSystem class into a
singleton.

Pavel Labath 1408bf7231 Remove TimeValue usage from FileSpec.h
Summary:
The only usage there was in GetModificationTime(). I also took the opportunity
to move this function from FileSpec to the FileSystem class - since we are
using FileSpecs to also represent remote files for which we cannot (easily)
retrieve modification time, it makes sense to make the decision to get the
modification time more explicit.

The new function returns a llvm::sys::TimePoint<>. To aid the transition
from TimeValue, I have added a constructor to it which enables implicit
conversion from a time_point.
