When an assertion like the following fails:
EXPECT_THAT(map, ElementsAre(Pair("p", "nullable"))));
Error message before:
Actual: { 40-byte object <E8-A5 9C-7F 25-37 00-00 58-7E 51-51 D0-7F 00-00 00-00 00-00 00-00 00-00 01-00 00-00 00-00 00-00 00-DA C7-7F 25-37 00-00> }
After:
Actual: { ("p", "nonnull") }
It is not ideal that we need to refer directly to DenseMapPair inside the
internal namespace, but I believe the practical maintenance risk is low.
This change is covered by DenseMap's unittests, as we've covered SmallString etc
in the past.

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.
Getting the Source Code and Building LLVM
Consult the Getting Started with LLVM page for information on building and running LLVM.

Getting in touch
Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
