14 months ago[CMake] Use LLVM own tools in extract_symbols.py
Igor Kudrin [Sat, 22 Apr 2023 03:01:10 +0000 (20:01 -0700)]
[CMake] Use LLVM own tools in extract_symbols.py

As for now, 'extract_symbols.py' can use several tools to extract
symbols from object files and libraries and to guess if the target is
32-bit Windows. The tools are being found via PATH, so in most cases,
they are just system tools. This approach has a number of limitations,
in particular:

* System tools may not be able to handle the target format in case of
  cross-platform builds,
* They cannot read symbols from LLVM bitcode files, so the staged LTO
  build with plugins is not supported,
* The auto-selected tools may be suboptimal (see D113557),
* Support for multiple tools for a single task increases the complexity
  of the script code.

The patch proposes using LLVM's own tools to solve these issues.
Specifically, 'llvm-readobj' detects the target platform, and 'llvm-nm'
reads symbols from all supported formats, including bitcode files. The
tools can be built in Release mode for the host platform or overridden
using CMake settings 'LLVM_READOBJ' and 'LLVM_NM' respectively. The
implementation also supports using precompiled tools via
'LLVM_NATIVE_TOOL_DIR'.

[lldb] Refine call to decl printing helper (NFC)

When `ValueObjectPrinter` calls its `m_decl_printing_helper`, not all state is passed to
the helper. In particular, the helper doesn't have access to `m_curr_depth`, and thus
can't act on the logic within `ShouldShowName`.

To address this, this change passes in a modified copy of `m_options`. The modified copy
has has `m_hide_name` set according to the results of `ShouldShowName`. This allows
helper functions to know whether the name should be shown or hidden, without having
access to `ValueObjectPrinter`'s full state.

This is NFC in mainline lldb, as the only decl printing helper doesn't make use of this.
However in swift-lldb at least, there are decl printing helpers that do need this
information passed to them. See https://github.com/apple/llvm-project/pull/6795 where a

[OpenMP] Implement task record and replay mechanism

This patch implements the "task record and replay" mechanism.  The idea is to be able to store tasks and their dependencies in the runtime so that we do not pay the cost of task creation and dependency resolution for future executions. The objective is to improve fine-grained task performance, both for those from "omp task" and "taskloop".

The entry point of the recording phase is __kmpc_start_record_task, and the end of record is triggered by __kmpc_end_record_task.

Tasks encapsulated between a record start and a record end are saved, meaning that the runtime stores their dependencies and structures, referred to as TDG, in order to replay them in subsequent executions. In these TDG replays, we start the execution by scheduling all root tasks (tasks that do not have input dependencies), and there will be no involvement of a hash table to track the dependencies, yet tasks do not need to be created again.

At the beginning of __kmpc_start_record_task, we must check if a TDG has already been recorded. If yes, the function returns 0 and starts to replay the TDG by calling __kmp_exec_tdg; if not, we start to record, and the function returns 1.

An integer uniquely identifies TDGs. Currently, this identifier needs to be incremented manually in the source code. Still, depending on how this feature would eventually be used in the library, the caller function must do it; also, the caller function needs to implement a mechanism to skip the associated region, according to the return value of __kmpc_start_record_task.

clang-format: [JS] terminate import sorting on `export type X = Y`

Contributed by @jankuehle!

https://reviews.llvm.org/D150116 introduced a bug. `export type X = Y` was considered an export declaration and took part in import sorting. This is not correct. With this change `export type X = Y` properly terminates import sorting.

confusing diagnostics that may hide the original error. An example:
```
// Start #include "SomeFile.h"

void Foo<T>::Bar(void* aRawPtr) {

}

With this patch, we only get the original error.

clangd can also benefit from this patch, as namespaces following the

[clang][dataflow] Don't analyze templated declarations.

Attempting to analyze templated code doesn't have a good cost-benefit ratio. We
have so far done a best-effort attempt at this, but maintaining this support has
an ongoing high maintenance cost because the AST for templates can violate a lot
of the invariants that otherwise hold for the AST of concrete code. As just one
example, in concrete code the operand of a UnaryOperator '*' is always a prvalue
(https://godbolt.org/z/s3e5xxMd1), but in templates this isn't true
(https://godbolt.org/z/6W9xxGvoM).

Further rationale for not analyzing templates:

* The semantics of a template itself are weakly defined; semantics can depend
  strongly on the concrete template arguments. Analyzing the template itself (as
  opposed to an instantiation) therefore has limited value.

* Analyzing templates requires a lot of special-case code that isn't necessary
  for concrete code because dependent types are hard to deal with and the AST
  violates invariants that otherwise hold for concrete code (see above).

* There's precedent in that neither Clang Static Analyzer nor the flow-sensitive
  warnings in Clang (such as uninitialized variables) support analyzing
  templates.
