GetDirtyPageList was being assigned to const & in most places anyway.
If you wanted to change the list you'd make a new one and call
SetDirtyPageList.
GetPageSize is just an int so no issues being const.

This patch adds a new `GetIndexForLineEntry` method to the `SBCompileUnit`
class. As the name suggests, given an `SBLineEntry` object, this will
return the line entry index within a specific compile unit.
This method can take a `exact` boolean that will make sure that the
provided line entry matches perfectly another line entry in the compile unit.

This patch moves the platform creation and selection logic into the
per-debugger platform lists. I've tried to keep functional changes to a
minimum -- the main (only) observable difference in this change is that
APIs, which select a platform by name (e.g.,
Debugger::SetCurrentPlatform) will not automatically pick up a platform
associated with another debugger (or no debugger at all).
I've also added several tests for this functionality -- one of the
pleasant consequences of the debugger isolation is that it is now
possible to test the platform selection and creation logic.

As noticed in D87637, when LLDB crashes, we only print stack traces if
LLDB is directly executed, not when used via Python bindings. Enabling
this by default may be undesirable (libraries shouldn't be messing with
signal handlers), so make this an explicit opt-in.
I "commandeered" this patch from Jordan Rupprecht who put this up for

This patch removes the ability to instantiate the LLDB FileSystem class
with a FileCollector. It keeps the ability to collect files, but uses
the FileCollectorFileSystem to do that transparently.
Because the two are intertwined, this patch also removes the
finalization logic which copied the files over out of process.
This patch changes the return value of Platform::GetName() to a
StringRef, and uses the opportunity (compile errors) to change some
callsites to use GetPluginName() instead. The two methods still remain
hardwired to return the same thing, but this will change once the ideas

This patch adds introduces a new kind of an lldbinit file. Unlike the
lldbinit in the home directory (useful for customizing lldb to the needs
of a particular user), or the cwd lldbinit file (useful for
project-specific settings), this file can be used to customize an entire
lldb installation to a particular environment.
The feature is enabled at build time, by setting the
LLDB_GLOBAL_INIT_DIRECTORY variable to a path to a directory which
should contain an "lldbinit" file. Lldb will then load the file at
startup, if it exists, and if automatic init loading has not been
disabled. Relative paths will be resolved (at runtime) relative to the
location of the lldb library (liblldb or LLDB.framework).
The system-wide lldbinit file will be loaded first, before any
$HOME/.lldbinit and $CWD/.lldbinit files are processed, so that those
can override any system-wide settings.
More information can be found on the RFC thread at
<https://discourse.llvm.org/t/rfc-system-wide-lldbinit/59933>.

This way if you have a long stack, you can issue "thread backtrace --count 10"
and then subsequent <Return>-s will page you through the stack.
This took a little more effort than just adding the repeat command, since
the GetRepeatCommand API was returning a "const char *". That meant the command
had to keep the repeat string alive, which is inconvenient. The original
API returned either a nullptr, or a const char *, so I changed the private API to
return an llvm::Optional<std::string>. Most of the patch is propagating that change.
Also, there was a little thinko in fetching the repeat command. We don't
fetch repeat commands for commands that aren't being added to history, which
is in general reasonable. And we don't add repeat commands to the history -
also reasonable. But we do want the repeat command to be able to generate
the NEXT repeat command. So I adjusted the logic in HandleCommand to work
that way.

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.

This macro was being used to select the proper import/export annotations
on SB classes. Non-windows clients do not have such requirements.
Instead introduce a new macro (LLDB_IN_LIBLLDB), which signals that
we're compiling liblldb itself (and should use dllexport). The default
(no macro) is to use dllimport. I've moved the macro definition to
SBDefines.h, since it only makes sense when building the API library.

Until the introduction of the C++ REPL, there was always a single REPL
language. Several places relied on this assumption through
repl_languages.GetSingularLanguage. Now that this is no longer the case,
we need a way to specify a selected/preferred REPL language. This patch
does that with the help of a debugger property, taking inspiration from
how we store the scripting language.

StructuredDataImpl ownership semantics is unclear at best. Various
structures were holding a non-owning pointer to it, with a comment that
the object is owned somewhere else. From what I was able to gather that
"somewhere else" was the SBStructuredData object, but I am not sure that
all created object eventually made its way there. (It wouldn't matter
even if they did, as we are leaking most of our SBStructuredData
objects.)
Since StructuredDataImpl is just a collection of two (shared) pointers,
there's really no point in elaborate lifetime management, so this patch
replaces all StructuredDataImpl pointers with actual objects or
unique_ptrs to it. This makes it much easier to resolve SBStructuredData
leaks in a follow-up patch.

Because of its dependency on clang (and potentially other compilers
downstream, such as swift) lldb_private::GetVersion already lives in its
own library called lldbBase. Despite that, its implementation was spread
across unrelated files. This patch improves things by introducing a
Version library with its own directory, header and implementation file.
The benefits of this patch include:
- We can get rid of the ugly quoting macros.
- Other parts of LLDB can read the version number from
lldb/Version/Version.inc.
- The implementation can be swapped out for tools like lldb-server than
don't need to depend on clang at all.

Right now if the LLDB is compiled under the windows with static vcruntime library, the -o and -k commands will not work.
The problem is that the LLDB create FILE* in lldb.exe and pass it to liblldb.dll which is an object from CRT.
Since the CRT is statically linked each of these module has its own copy of the CRT with it's own global state and the LLDB should not share CRT objects between them.
In this change I moved the logic of creating FILE* out of commands stream from Driver class to SBDebugger.
To do this I added new method: SBError SBDebugger::SetInputStream(SBStream &stream)
Command to build the LLDB:
cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang;lldb;libcxx" -DLLVM_USE_CRT_RELEASE="MT" -DLLVM_USE_CRT_MINSIZEREL="MT" -DLLVM_USE_CRT_RELWITHDEBINFO="MT" -DP

Command which will fail:
