[sancov] Add -diff and -union options to compute set difference and union of sancov files  (#171191)

Add two new actions for `.sancov` files:

`-diff`: Computes the difference between two `.sancov` files (A - B) and
writes the result to a new file. Requires exactly two inputs and an
`--output` option. The output preserves the binary format (magic number
and bitness) of the first input.

`-union`: Computes the union of one or more `.sancov` files and writes
the result to a new file. Requires at least one input and an `--output`
option. The output preserves the binary format of the first input.

A warning is shown if input files differ in bitness (32-bit vs 64-bit),
but the operation proceeds using the first file’s bitness.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

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.

Getting the Source Code and Building LLVM

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.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

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