[analyzer] Suppress NewDeleteLeaks FP in protobuf code (#162124) Code automatically generated by protobuf can include a pattern where it allocates memory with `new` and then passes it to a function named `GetOwnedMessageInternal` which takes ownership of the allocated memory. This caused large amounts of false positives on a system where the protobuf header was included as a system header and therefore the analyzer assumed that `GetOwnedMessageInternal` won't escape memory. As we already individually recognize a dozen functions that can be declared in system headers but can escape memory, this commit just adds `GetOwnedMessageInternal` to that list. On a longer term perhaps we should distinguish the standard library headers (where the analyzer can assume that it recognizes all the functions that can free/escape memory) and other system headers (where the analyzer shouldn't make this assumption).
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.
