Something went wrong with r211426, it is an older version of this code
and should not have been committed. It was reverted with r211434.
Original commit message:
We didn't properly implement support for the sized integer suffixes.
Suffixes like i16 were essentially ignored instead of mapping them to
the appropriately sized integer type.
This fixes PR20008.

These are commonly used to structure things like enums or long braced

This corrects long-standing misuses of LLVM's internal config.h.
In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.
The config.h header is private, won't be installed and should no longer be
included by clang or other modules.

There is a pattern where evaluation order is used as control flow.
This patch special-cases a commonly occuring version of this pattern.

Eliminate createMainFileID() / createMainFileIDForMemBuffer() utility

The result of getBufferForFile() must be freed.

This patch ensures that the lines of the block comments retain relative
column offsets. In order to do this WhitespaceManager::Changes representing

change, so that the correct column can be reconstructed at the end of alignment
process.

More precisely keep all short annotations (<10 characters) on the same
line if possible. Previously, clang-format would only prefer to do so
for "const", "override" and "final". However, it seems to be generally
preferable, especially because some codebases have to wrap those in
macros for backwards compatibility.

Before AllowShortFunctionsOnASingleLine could either be true, merging

For namespaces, this is consistent with mangling and GCC's debug info
behavior. For structs, GCC uses <anonymous struct> but we prefer
consistency between all anonymous entities but don't want to confuse

cases.

This follows the LLVM change to canonicalise the Windows target triple

Two DynTypedNodes can be equal if they do not have the same node type,

Due to not resetting the fake rparen data on the token when iterating
over annotated lines, we would pop the last element of the paren stack.
This patch fixes the underlying root cause, and makes the code more
robust against similar problems in the future:
- reset the first token when iterating on the same annotated lines due
to preprocessor branches
- never pop the last element from the paren stack, so we do not crash,
but rather incorrectly format
- add assert()s so we can figure out if our assumptions are violated

a missing include from CLog.h.
CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.

It isn't appropriate for a tool to be stomping over the dependency files,
especially if the actual build uses a compiler other than Clang or the tool
cannot find all the headers for some reason (which would cause the existing
dependency file to be deleted).
If a tool actually needs to care about dependency files we can think about
adding a mechanism for getting to this information.

Was r202442
There were two issues with the original patch that have now been fixed.
1. We were memset'ing over a FileEntry in a test case. After adding a
std::string to FileEntry, this still happened to not break for me.
2. I didn't pass the FileManager into the new compiler instance in
compileModule. This was hidden in some cases by the fact I didn't
clear the module cache in the test.
Also, I changed the copy constructor for FileEntry, which was memcpy'ing
in a (now) unsafe way.
