2025-06-14[clang-tidy][NFC] change patterns 'anyOf(..., anything())' to ↵Baranov Victor1-8/+5
'optionally(...)' (#143558) Writing `optionally()` instead of `anyOf(..., anything())` lowers code size and gives the author's intention better.
2025-05-25[clang-tidy] Remove unused includes (NFC) (#141420)Kazu Hirata1-2/+0
These are identified by misc-include-cleaner. I've filtered out those that break builds. Also, I'm staying away from llvm-config.h, config.h, and Compiler.h, which likely cause platform- or compiler-specific build failures.
2024-01-12[clang-tidy] Fix false-positives in misc-static-assert caused by ↵Piotr Zegar1-1/+9
non-constexpr variables (#77203) Ignore false-positives when referring to non-constexpr variables in non-unevaluated context (like decltype, sizeof, ...). Moved from https://reviews.llvm.org/D158657 Fixes: #24066

2023-01-07[clang-tools-extra] Use std::optional instead of llvm::Optional (NFC)Kazu Hirata1-1/+1
This patch replaces (llvm::|)Optional< with std::optional<. I'll post a separate patch to clean up the "using" declarations, #include "llvm/ADT/Optional.h", etc. This is part of an effort to migrate from llvm::Optional to std::optional: https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
2023-01-07[clang-tools-extra] Add #include <optional> (NFC)Kazu Hirata1-0/+1
This patch adds #include <optional> to those files containing llvm::Optional<...> or Optional<...>. I'll post a separate patch to actually replace llvm::Optional with std::optional. This is part of an effort to migrate from llvm::Optional to std::optional: https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716

2021-05-30Revert "[clang-tidy] Simplify static assert check"Roman Lebedev1-19/+30
This patch starts to produce a very obvious false-positives, despite the fact the preexisting tests already cover the pattern. they clearly don't actually cover it. https://godbolt.org/z/3zdqvbfxj This reverts commit 1709bb8c7395418236ec94fe3b9d91fed746452b.
2021-03-01[clang-tidy] Tweak misc-static-assert fix in c++17Nathan James1-5/+4
If C++17 mode is enabled and the assert doesn't have a string literal, we can emit a static assert with no message in favour of one with an empty message. Reviewed By: aaron.ballman Differential Revision: https://reviews.llvm.org/D97313

2020-10-15clang-{tools,unittests}: Stop using SourceManager::getBuffer, NFCDuncan P. N. Exon Smith1-1/+2
Update clang-tools-extra, clang/tools, clang/unittests to migrate from `SourceManager::getBuffer`, which returns an always dereferenceable `MemoryBuffer*`, to `getBufferOrNone` or `getBufferOrFake`, both of which return a `MemoryBufferRef`, depending on whether the call site was checking for validity of the buffer. No functionality change intended. Differential Revision: https://reviews.llvm.org/D89416

2019-04-04Make SourceManager::createFileID(UnownedTag, ...) take a const ↵Nico Weber1-1/+1
llvm::MemoryBuffer* Requires making the llvm::MemoryBuffer* stored by SourceManager const, which in turn requires making the accessors for that return const llvm::MemoryBuffer*s and updating all call sites. The original motivation for this was to use it and fix the TODO in CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag version of createFileID, and since llvm::SourceMgr* hands out a const llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO this way actually works, but this seems like a good change on its own anyways. No intended behavior change.

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+3
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. llvm-svn: 351636

2016-05-03[clang-tidy] Speedup misc-static-assert.Samuel Benzaquen1-3/+7
Summary: Speedup the misc-static-assert check by not use `stmt()` as the toplevel matcher. The framework runs a filter on the matchers before trying them on each node and uses the toplevel type for this. Using `stmt()` as the toplevel causes the matcher to be run on every `Stmt` node, even if the node doesn't match the desired types. This change speeds up clang-tidy by ~5% in a benchmark.

This patch contains two assert related checkers. These checkers are the part of those that is being open sourced by Ericsson (http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-December/040520.html). The checkers: AssertSideEffect: /// \brief Finds \c assert() with side effect. /// /// The conition of \c assert() is evaluated only in debug builds so a condition /// with side effect can cause different behaviour in debug / relesase builds. StaticAssert: /// \brief Replaces \c assert() with \c static_assert() if the condition is /// evaluatable at compile time. /// /// The condition of \c static_assert() is evaluated at compile time which is /// safer and more efficient. http://reviews.llvm.org/D7375 Patch by Szabolcs Sipos! llvm-svn: 230943
