TestCPPAuto was only failing on windows due to the std::string
copying (which was not related at all to 'auto' functionality).
TestStepTarget is now also passing but that seems more that we
now have by accident the right behavior in Windows. I'll remove
the x-fail just to make the bot green again.
The only thing needed was to account for the offset from the
debug_cu_index section when searching for the location list.
This patch also fixes a bug in the Module::ParseAllDebugSymbols
function, which meant that we would only parse the variables of the
first compile unit in the module. This function is only used from
lldb-test, so this does not fix any real issue, besides preventing me
from writing a test for this patch.
Comparing those two `const char *` values relies on the assumption that both
strings were created by a ConstString. Let's check that assumption with an
assert as otherwise this code silently does nothing and that's not great.
This should use -> instead of '.', but the fix-it functionality of
the expression evaluator saved us here. Let's use the proper syntax
in the first place as we don't want to test fix-its here.
This directory escaped the modularization effort it seems. Just adding
this to the Host module along with the other common headers, which should
make this code less likely to break under modules and speed up compilation.
Summary:
Currently when printing data types we include implicit scopes such as inline namespaces or anonymous namespaces.
This leads to command output like this (for `std::set<X>` with X being in an anonymous namespace):
```
(lldb) print my_set
(std::__1::set<(anonymous namespace)::X, std::__1::less<(anonymous namespace)::X>, std::__1::allocator<(anonymous namespace)::X> >) $0 = size=0 {}
```
This patch removes all the implicit scopes when printing type names in TypeSystemClang::GetDisplayTypeName
so that our output now looks like this:
```
(lldb) print my_set
(std::set<X, std::less<X>, std::allocator<X> >) $0 = size=0 {}
```
As previously GetDisplayTypeName and GetTypeName had the same output we actually often used the
two as if they are the same method (they were in fact using the same implementation), so this patch also
fixes the places where we actually want the display type name and not the actual type name.
Note that this doesn't touch the `GetTypeName` class that for example the data formatters use, so this patch
is only changes the way we display types to the user. The full type name can also still be found when passing
'-R' to see the raw output of a variable in case someone is somehow interested in that.

All calls to operator new in this test fail for me with:
```
expression --show-types -- *(new foo(47))`
Error output:
error: Execution was interrupted, reason: internal c++ exception breakpoint(-6)..
The process has been returned to the state before expression evaluation.
```
As calling operator new isn't the idea of this test, this patch moves that
logic to the binary with some new_* utility functions and explicitly tests
this logic in the constructor test (where we can isolate the failures and
skip them on Linux).
The PluginManager contains a lot of duplicate code. I already removed a
bunch of it by introducing the templated PluginInstance class, and this
is the next step. The PluginInstances class combines the mutex and the
vector and implements the common operations.
To accommodate plugin instances with additional members it is possible
to access the underlying vector and mutex. The methods to query these
fields make use of that.

This patch changes the way we initialize and terminate the plugins in
the system initializer. It uses an approach similar to LLVM's
TARGETS_TO_BUILD with a def file that enumerates the plugins.
Previous attempts to land this failed on the Windows bot because there's
a dependency between the different process plugins. Apparently
ProcessWindowsCommon needs to be initialized after all other process
plugins but before ProcessGDBRemote.

The plugin manager had dedicated Get*PluginCreateCallbackForPluginName
methods for each type of plugin, and only a small subset of those were
used. This removes the dead duplicated code.
The WASM and Hexagon plugin check the ArchType rather than the OSType,
so explicitly reject those in the DynamicLoaderStatic.

Generate the LLDB_PLUGIN_DECLARE macros with CMake and a def file. I'm
landing D73067 in pieces so I can bisect what exactly is breaking the
Windows bot.
Other plugins depend on DynamicLoaderDarwinKernel and which means we
cannot conditionally enable/build this plugin based on the target
platform. This means that it will be past of the list of plugins
initialized once that's autogenerated.
The two classes are equivalent, except:
- the former uses a llvm::SmallVector (with a configurable size), while
the latter uses std::vector.
- the former has a typo in one of the functions name
This patch just leaves one class, using llvm::SmallVector, and defaults
the small size to zero. This is the same thing we did with the
RangeDataVector class in D56170.
This patch enables the debug entry values feature.
- Remove the (CC1) experimental -femit-debug-entry-values option
- Enable it for x86, arm and aarch64 targets
- Resolve the test failures
- Leave the llc experimental option for targets that do not
support the CallSiteInfo yet

Summary:
Follow up to an issue pointed out in the review of D73808. We shouldn't just pass in a nullptr TypeSourceInfo
in case Clang decided to access it.

Pass TargetSP to filters' CreateFromStructuredData, don't let them guess
whether target object is managed by a shared_ptr.
Make Breakpoint sure that m_target.shared_from_this() is safe by passing TargetSP
to all its static Create*** member-functions. This should be enough, since Breakpoint's
constructors are private/protected and never called directly (except by Target itself).
Since f9568a9549 this function takes a
CompilerDeclContext reference instead of a pointer. It overlooked this function
when I fixed the compilation for FindTypes.
Summary:
Currently the data formatter is treating `std::atomic` variables as transparent wrappers
around their underlying value type. This causes that when printing `std::atomic<A *>`, the data
formatter will forward all requests for the children of the atomic variable to the `A *` pointer type
which will then return the respective members of `A`. If `A` in turn has a member that contains
the original atomic variable, this causes LLDB to infinitely recurse when printing an object with
such a `std::atomic` pointer member.
We could implement a workaround similar to whatever we do for pointer values but this patch
just implements the `std::atomic` formatter in the same way as we already implement other
formatters (e.g. smart pointers or `std::optional`) that just model the contents of the as a child
"Value". This way LLDB knows when it actually prints a pointer and can just use its normal
workaround if "Value" is a recursive pointer.

Summary:
In dwp files a constant (from the debug_cu_index section) needs to be
added to each reference into the debug_str_offsets section.
I've tried to implement this to roughly match the llvm flow: I've
changed the DWARFormValue to stop resolving the indirect string
references directly -- instead, it calls into DWARFUnit, which resolves
this for it (similar to how it already resolves indirect range and
location list references). I've also done a small refactor of the string
offset base computation code in DWARFUnit in order to make it easier to
access the debug_cu_index base offset.

This should be just the enum type but that's a larger refactoring, so document that
this is not just an integer until we can make this just the type of the enum.
Summary:
All of our lookup APIs either use `CompilerDeclContext &` or `CompilerDeclContext *` semi-randomly it seems.
This leads to us constantly converting between those two types (and doing nullptr checks when going from
pointer to reference). It also leads to the confusing situation where we have two possible ways to express
that we don't have a CompilerDeclContex: either a nullptr or an invalid CompilerDeclContext (aka a default
constructed CompilerDeclContext).
This moves all APIs to use references and gets rid of all the nullptr checks and conversions.
