[clang-tidy][NFC] Do less unnecessary work in `NoLintDirectiveHandler` (#147553) Summary: - `NoLintBlockToken` is too big: it stores a whole `NoLintToken` inside itself, when all it needs from that `NoLintToken` is its `Pos` and `ChecksGlob`. - `formNoLintBlocks` builds up a vector of unmatched tokens, which are later transformed into errors. We can skip the middle step and make `formNoLintBlocks` create errors directly. - In `generateCache`, the line `Cache[FileName] = ...;` default-constructs a cache entry only to immediately overwrite it. We can avoid that by using `Cache.try_emplace(FileName, ...);` instead. - `NoLintToken`'s constructor takes `const std::optional<std::string>&` when all it needs is `const std::optional<StringRef>&`. This forces its caller, `getNoLints`, to create temporary strings. - `NoLintToken::checks` returns `std::optional<std::string>` by value, creating unnecessary copies in `formNoLintBlocks`.
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
