[lldb][Process/FreeBSDKernelCore] Add command for refreshing thread list (#188692) Since `/dev/mem` is live memory, its thread list is updated while running LLDB. In the current model, users need to restart LLDB to get new thread list, and this is prone to error when writing to memory because LLDB's thread information and `/dev/mem` might be out of sync. The new command `process plugin refresh-threads` reconstructs thread list so users can synchronize thread list without restarting lldb. Memory cache needs to be cleared prior to reconstruction otherwise lldb will read the same process information from cache memory. To invoke `UpdateThreadList()` from `UpdateThreadListIfNeeded()`, clear thread list as well before triggering an update. This is enabled for all kvm invocation regardless of type of the target (crash dump or live kernel) because kvm hides the target type information. Elf-core based implementation in future will need to update thread list only at the first time as it is guaranteed that elf-core handles static files. --------- Signed-off-by: Minsoo Choo <minsoochoo0122@proton.me>
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
