llvm-mirror/include/llvm/Support/InitLLVM.h
Chandler Carruth ae65e281f3 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

// The main() functions in typical LLVM tools start with InitLLVM which does
// the following one-time initializations:
//
// 1. Setting up a signal handler so that pretty stack trace is printed out
// if a process crashes.
//
// 2. If running on Windows, obtain command line arguments using a
// multibyte character-aware API and convert arguments into UTF-8
// encoding, so that you can assume that command line arguments are
// always encoded in UTF-8 on any platform.
//
// InitLLVM calls llvm_shutdown() on destruction, which cleans up
// ManagedStatic objects.
