[libc++] Rewrite the transitive header checking machinery (#110554)

Since we don't generate a full dependency graph of headers, we can
greatly simplify the script that parses the result of --trace-includes.

At the same time, we also unify the mechanism for detecting whether a
header is a public/C compat/internal/etc header with the existing
mechanism in header_information.py.

As a drive-by this fixes the headers_in_modulemap.sh.py test which had
been disabled by mistake because it used its own way of determining
the list of libc++ headers. By consistently using header_information.py
to get that information, problems like this shouldn't happen anymore.

This should also unblock #110303, which was blocked because of
a brittle implementation of the transitive includes check which broke
when the repository was cloned at a path like /path/__something/more.

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
