This patch removes undefined behavior in list and forward_list and __hash_table caused by improperly beginning and ending the lifetime of the various node classes. It allows removing the _LIBCPP_STANDALONE_DEBUG macro from these node types since we now properly begin and end their lifetime, meaning that we won't trip up constructor homing. See https://reviews.llvm.org/D98750 for more information on what prompted this patch. This commit re-applies 0687e4d9f310, which had been reverted in b935882bdce7 because it broke the LLDB build. LLDB folks tell me I can go ahead and re-commit this now. Differential Revision: https://reviews.llvm.org/D101206 Co-authored-by: Amy Kwan <amy.kwan1@ibm.com>
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.
