Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

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.

Fix llvm-for-windows-on-linux build after LLVM r272701.

2017-08-03T20:10:47+00:00

The file is called "intrin.h". When building targeting Windows on a Linux
system, with the SDK mounted in a case-insensitive file system, "Intrin.h" will
miss clang's intrin.h header (because that's not in a case-insensitive file
system) but then find intrin.h in the Microsoft SDK. clang can't handle the
SDK's intrin.h.

Fix another ordering constraint with windows.h and comment about

a revers constraint that we got right (by chance).

llvm-svn: 304792

Remove all of the legacy home-grown atomic operations LLVM provided

2016-06-02T17:11:11+00:00

except for CompareAndSwap. That is the only one still being used
anywhere now that statistics have been moved onto std::atomic.

Also, add a warning to the header that we shouldn't introduce more uses
of these old style atomics and instead should be using C++11's
std::atomic facilities.

Really hoping that we can hammer out the last couple of users here and
replace them with something more localized and/or principled, but
figured this was a pretty good start. =]

Note that this patch will need to be reverted if r271504 needs to be
reverted as that removes the last user of these. However, the biggest
risk for that patch was MSVC 2013 and at least one bot has already
passed where it would have failed there. I've tested MSVC 2015 using
their web interfaces and other platforms seem fine, so I'm optimistic.

Include intrin.h before windows.h as a workaround for the x64 self-host

2014-05-06T00:57:33+00:00

On x64, windows.h doesn't include intrin.h for intrinsics.  It just
declares them in the global namespace and uses them, expecting the
compiler to lower it as a builtin.  We basically need to do this in
clang, eventually.

XLC supports the same atomic functions as GCC, use them.
