Harlan Haskins 8d323d1506 [clang] Adopt new FileManager error-returning APIs
Update the callers of FileManager::getFile and FileManager::getDirectory to handle the new llvm::ErrorOr-returning methods.

Chandler Carruth 2946cd7010 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.

Antonio Maiorano 3adfb6a3ee clang-format: Make GetStyle return Expected<FormatStyle> instead of FormatStyle
Change the contract of GetStyle so that it returns an error when an error occurs
(i.e. when it writes to stderr), and only returns the fallback style when it
can't find a configuration file.

Eric Liu cf2913c6f1 Deduplicate replacements by FileEntry instead of file names.
Summary:
The current version does not deduplicate equivalent file paths correctly.
For example, a relative path and an absolute path are considered inequivalent.
Comparing FileEnry addresses these issues.

Eric Liu cefe763dd2 Deduplicate sets of replacements by file names.
Summary:
If there are multiple <File, Replacements> pairs with the same file
path after removing dots, we only keep one pair (with path after dots being
removed) and discard the rest.

Eric Liu 40ef2fb363 Implement tooling::Replacements as a class.
Summary:
- Implement clang::tooling::Replacements as a class to provide interfaces to
  control how replacements for a single file are combined and provide guarantee
  on the order of replacements being applied.
- tooling::Replacements only contains replacements for the same file now.
  Use std::map<std::string, tooling::Replacements> to represent multi-file
  replacements.
- Error handling for the interface change will be improved in followup patches.

Adrian Prantl bb165fb04d Introduce a PCHContainerOperations interface (NFC).
A PCHContainerOperations abstract interface provides operations for
creating and unwrapping containers for serialized ASTs (precompiled
headers and clang modules). The default implementation is
RawPCHContainerOperations, which uses a flat file for the output.

The main application for this interface will be an
ObjectFilePCHContainerOperations implementation that uses LLVM to
wrap the module in an ELF/Mach-O/COFF container to store debug info
alongside the AST.

Daniel Jasper cb3e6188bc Refactor libTooling to reduce required dependencies.
This moves classes for storing and applying replacements to separate
files. These classes specifically are used by clang-format which doesn't
have any other dependencies on clangAST. Thereby, the size of
clang-format's binary can be cut roughly in half and its build time sped
up.

Benjamin Kramer efffbee024 Tooling: Ignore file names in tooling::deduplicate.
This was horribly broken due to how the sort predicate works. We would
report a conflict for files with a replacement in the same position but
different names if the length differed. Just ignore paths as this is often
what the user wants. Files can occur with different names (due to symlinks
or relative paths) and we don't ever want to do the same edit in one file
twice.

David Blaikie 49cc3181a2 Overload SourceManager::overrideFileContents so that unconditionally passing ownership is explicitly done using unique_ptr.
Only those callers who are dynamically passing ownership should need the
3 argument form. Those accepting the default ("do pass ownership")
should do so explicitly with a unique_ptr now.

During the transition of clang::tooling::Replacements from std::set to

duplicated to take a std::vector<Replacement>. Applying this same temporary

One day soon, tooling::Replacements will be changed from being implemented as

applyAllReplacements that takes a vector.

Daniel Jasper 2a250b8b49 Let clang-format move the cursor appropriately.
With this patch, clang-format will try to keep the cursor at the
original code position in editor integrations (implemented for emacs and
vim). This means, after formatting, clang-format will try to keep the
cursor on the same character of the same token.

Daniel Jasper ec04c0dba0 Add a more convenient interface to use clang-format.
It turns out that several implementations go through the trouble of
setting up a SourceManager and Lexer and abstracting this into a
function makes usage easier.

Also abstracts SourceManager-independent ranges out of
tooling::Refactoring and provides a convenience function to create them
from line ranges.

Edwin Vane 5038ac0fb8 Allow RefactoringTool to write to memory instead of always to disk
RefactoringTool::run() always writes the result of rewrites to disk.
Instead, make this optional and provide a method for getting the
refactoring results in a memory buffer instead.

Also made ClangTool polymorphic so RefactoringTool could inherit from it
to properly express the IS-A relationship. This change also provides
access to ClangTool's public interface, e.g. mapVirtualFile() which is
important once refactored buffers start living in memory instead of on
disk.
