This is a continuation of 68fd102, which did the same thing but only for
StopInfo. Using make_shared is both safer and more efficient:
- With make_shared, the object and the control block are allocated
together, which is more efficient.
- With make_shared, the enable_shared_from_this base class is properly
linked to the control block before the constructor finishes, so
shared_from_this() will be safe to use (though still not recommended
during construction).

This patch pushes the error handling boundary for the GetBitSize()
methods from Runtime into the Type and CompilerType APIs. This makes it
easier to diagnose problems thanks to more meaningful error messages
being available. GetBitSize() is often the first thing LLDB asks about a
type, so this method is particularly important for a better user
experience.

constants (#127206)
This patch adds support for template arguments of
`clang::TemplateArgument::ArgKind::StructuralValue` kind (added in
https://github.com/llvm/llvm-project/pull/78041). These are used for
non-type template parameters such as floating point constants. When LLDB
created `clang::NonTypeTemplateParmDecl`s, it previously assumed
integral values, this patch accounts for structural values too.
Anywhere LLDB assumed a `DW_TAG_template_value_parameter` was
`Integral`, it will now also check for `StructuralValue`, and will
unpack the `TemplateArgument` value and type accordingly.
We can rely on the fact that any `TemplateArgument` of `StructuralValue`
kind that the `DWARFASTParserClang` creates will have a valid value,
because it gets those from `DW_AT_const_value`.
|
|
This patch adds a new API to `SBType` to retrieve the value of a
template parameter given an index. We re-use the
`TypeSystemClang::GetIntegralTemplateArgument` for this and thus
currently only supports integral non-type template parameters. Types
like float/double are not supported yet.

ValueObject is part of lldbCore for historical reasons, but conceptually
it deserves to be its own library. This does introduce a (link-time) circular
dependency between lldbCore and lldbValueObject, which is unfortunate
but probably unavoidable because so many things in LLDB rely on
ValueObject. We already have cycles and these libraries are never built
as dylibs so while this doesn't improve the situation, it also doesn't
make things worse.
The header includes were updated with the following command:
```
find . -type f -exec sed -i.bak "s%include \"lldb/Core/ValueObject%include \"lldb/ValueObject/ValueObject%" '{}' \;
```

lldb already mostly(*) tracks this information. This just makes it
available to the SB users.
(*) It does not do that for typedefs right now see llvm.org/pr90958
|
|
The main change is the addition of a new SBTypeStaticField class,
representing a static member of a class. It can be retrieved created
through SBType::GetStaticFieldWithName. It contains several methods
(GetName, GetMangledName, etc.) whose meaning is hopefully obvious. The
most interesting method is
lldb::SBValue GetConstantValue(lldb::SBTarget)
which returns a the value of the field -- if it is a compile time
constant. The reason for that is that only constants have their values
represented in the clang AST.
For non-constants, we need to go back to the module containing that
constant, and ask retrieve the associated ValueObjectVariable. That's
easy enough if the we are still in the type system of the module
(because then the type system will contain the pointer to the module
symbol file), but it's hard when the type has been copied into another
AST (e.g. during expression evaluation). To do that we would need to
walk the ast import chain backwards to find the source TypeSystem, and I
haven't found a nice way to do that.
Another possibility would be to use the mangled name of the variable to
perform a lookup (in all modules). That is sort of what happens when
evaluating the variable in an expression (which does work), but I did
not want to commit to that implementation as it's not necessary for my
use case (and if anyone wants to, he can use the GetMangledName function
and perform the lookup manually).
The patch adds a couple of new TypeSystem functions to surface the
information needed to implement this functionality.

This patch adds a `SBType::FindDirectNestedType(name)` function which performs a non-recursive search in given class for a type with specified name. The intent is to perform a fast search in debug info, so that it can be used in formatters, and let them remain responsive.
This is driven by my work on formatters for Clang and LLVM types. In particular, by [`PointerIntPairInfo::MaskAndShiftConstants`](https://github.com/llvm/llvm-project/blob/cde9f9df79805a0850310870d6dcc64004292727/llvm/include/llvm/ADT/PointerIntPair.h#L174C16-L174C16), which is required to extract pointer and integer from `PointerIntPair`.

LLDB should guarantee that the strings returned by SBAPI methods
live forever. I went through every method that returns a string and made
sure that it was added to the ConstString StringPool before returning if
it wasn't obvious that it was already doing so.
I've also updated the docs to document this behavior.

-flimit-debug-info and other compiler options might end up removing debug info that is needed for debugging. LLDB marks these types as being forcefully completed in the metadata in the TypeSystem. These types should have been complete in the debug info but were not because the compiler omitted them to save space. When we can't find a suitable replacement for the type, we should let the user know that these types are incomplete to indicate there was an issue instead of just showing nothing for a type.
The solution is to display presented in this patch is to display "<incomplete type>" as the summary for any incomplete types. If there is a summary string or function that is provided for a type, but the type is currently forcefully completed, the installed summary will be ignored and we will display "<incomplete type>". This patch also exposes the ability to ask a SBType if it was forcefully completed with:
bool SBType::IsTypeForcefullyCompleted();
This will allow the user interface for a debugger to also detect this issue and possibly mark the variable display up on some way to indicate to the user the type is incomplete.
To show how this is diplayed, we can look at the existing output first for the example source file from the file: lldb/test/API/functionalities/limit-debug-info/main.cpp

When a process gets restarted TypeSystem objects associated with it
may get deleted, and any CompilerType objects holding on to a
reference to that type system are a use-after-free in waiting. Because
of the SBAPI, we don't have tight control over where CompilerTypes go
and when they are used. This is particularly a problem in the Swift
plugin, where the scratch TypeSystem can be restarted while the
process is still running. The Swift plugin has a lock to prevent
abuse, but where there's a lock there can be bugs.
This patch changes CompilerType to store a std::weak_ptr<TypeSystem>.
Most of the std::weak_ptr<TypeSystem>* uglyness is hidden by
introducing a wrapper class CompilerType::WrappedTypeSystem that has a
dyn_cast_or_null() method. The only sites that need to know about the
weak pointer implementation detail are the ones that deal with
creating TypeSystems.

When looking at template arguments in LLDB, we usually care about what
the user passed in his code, not whether some of those arguments where
passed as a variadic parameter pack.
This patch extends all the C++ APIs to look at template parameters to
take an additional 'expand_pack' boolean that automatically unwraps the
potential argument packs. The equivalent SBAPI calls have been changed
to pass true for this parameter.
A byproduct of the patch is to also fix the support for template type
that have only a parameter pack as argument (like the OnlyPack type in
the test). Those were not recognized as template instanciations before.
The added test verifies that the SBAPI is able to iterate over the
arguments of a variadic template.
The original patch was written by Fred Riss almost 4 years ago.

This patch has no effect for C and C++. In more dynamic languages,
such as Objective-C and Swift GetByteSize() needs to call into the
language runtime, so it's important to pass one in where possible. My
primary motivation for this is some work I'm doing on the Swift
branch, however, it looks like we are also seeing warnings in
Objective-C that this may resolve. Everything in the SymbolFile
hierarchy still passes in nullptrs, because we don't have an execution
context in SymbolFile, since SymbolFile transcends processes.

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:
Motivation: When formatting an array of typedefed chars, we would like to display the array as a string.
The string formatter currently does not trigger because the formatter lookup does not resolve typedefs for array elements (this behavior is inconsistent with pointers, for those we do look through pointee typedefs). This patch tries to make the array formatter lookup somewhat consistent with the pointer formatter lookup.

Testing whether a name is mangled or not is extremely cheap and can be
done by looking at the first two characters. Mangled knows how to do
it. On the flip side, many call sites that currently pass in an
is_mangled determination do not know how to correctly do it (for
example, they leave out Swift mangling prefixes).
This patch removes this entry point and just forced Mangled to
determine the mangledness of a string itself.

For some reason I had convinced myself that functions returning by
pointer or reference do not require recording their result. However,
after further considering I don't see how that could work, at least not
with the current implementation. Interestingly enough, the reproducer

lldb-instr tool did not.

Summary:
Our python version of the SB API has (the python equivalent of)
operator bool, but the C++ version doesn't.
This is because our python operators are added by modify-python-lldb.py,
which performs postprocessing on the swig-generated interface files.
In this patch, I add the "operator bool" to all SB classes which have an
IsValid method (which is the same logic used by modify-python-lldb.py).
This way, we make the two interfaces more constent, and it allows us to
rely on swig's automatic syntesis of python __nonzero__ methods instead
of doing manual fixups.

The current record macros already log the function being called. This
patch extends the macros to also log their input arguments and removes
explicit logging from the SB API.
This might degrade the amount of information in some cases (because of
smarter casts or efforts to log return values). However I think this is
outweighed by the increased coverage and consistency. Furthermore, using
the reproducer infrastructure, diagnosing bugs in the API layer should
become much easier compared to relying on log messages.

My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.
ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by

value makes it harder to accidentally return the address of a local
object.

The `ap` suffix is a remnant of lldb's former use of auto pointers,

unique pointers, some variables still carried the suffix.

::get for unique_pointers. Jim justly noted that this is a good
opportunity to clean up the variable names as well.
I went over all the changes to ensure my find-and-replace didn't have

Essentially, all code in the project is now made available by the LLVM

The code in LLDB assumes that CompilerType and friends use the size 0
as a sentinel value to signal an error. This works for C++, where no
zero-sized type exists, but in many other programming languages
(including I believe C) types of size zero are possible and even
common. This is a particular pain point in swift-lldb, where extra
code exists to double-check that a type is *really* of size zero and
not an error at various locations.
To remedy this situation, this patch starts by converting
CompilerType::getBitSize() and getByteSize() to return an optional
result. To avoid wasting space, I hand-rolled my own optional data
type assuming that no type is larger than what fits into 63
bits. Follow-up patches would make similar changes to the ValueObject
hierarchy.

Summary:
llvm::APSInt(0) asserts because it creates an int with bit-width 0 and
not (as I thought) a value 0.
Theoretically it should be sufficient to change this to APSInt(1), as
the intention there was that the value of the first argument should be
ignored if the type is invalid, but that would look dodgy.
Instead, I use llvm::Optional to denote an invalid value and use a
special struct instead of a std::pair, to reduce typing and increase
clarity.

Summary:
Despite it's name, GetTemplateArgument was only really working for Type
template arguments. This adds the ability to retrieve integral arguments
as well (which I've needed for the std::bitset data formatter).
I've done this by splitting the function into three pieces. The idea is
that one first calls GetTemplateArgumentKind (first function) to
determine the what kind of a parameter this is. Based on that, one can
then use specialized functions to retrieve the correct value. Currently,
I only implement two of these: GetTypeTemplateArgument and
GetIntegralTemplateArgument.

All references to Host and Core have been removed, so this
class can now safely be lowered into Utility.

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.
