During the initialization sequence in our tests the first 'threads' response sould only be kept if the process is actually stopped, otherwise we will have stale data. In VSCode, during the debug session startup sequence immediately after 'configurationDone' a 'threads' request is made. This initial request is to retrieve the main threads name and id so the UI can be populated. However, in our tests we do not want to cache this value unless the process is actually stopped. We do need to make this initial request because lldb-dap is caching the initial thread list during configurationDone before the process is resumed. We need to make this call to ensure the cached initial threads are purged. I noticed this in a CI job for another review (https://github.com/llvm/llvm-project/actions/runs/19348261989/job/55353961798) where the tests incorrectly failed to fetch the threads prior to validating the thread names.
The LLVM Compiler Infrastructure
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.
