* Clean up and rework DXIL library depencencies
This change reworks the dependency specifications for the DXIL*
libraries. Many of these libraries had over and under specified
dependencies.
This also collapses the DxilRDATBuidlder into the DxilContainer library
to remove the cyclic dependency between the two libraries.
* Break assert dependency between DXIL and Analysis
In assert builds the DXILModule constructor was creating forced bindings
to debugging methods that are often used from the debugger. This forced
binding is useful, but doesn't need to live in the DXIL library.
To break the dependency I've moved the code into Analysis. I've also
made that code only included when building with MSVC. When using other
compilers `__attribute__((used))` can be applied to the function via the
`LLVM_DUMP_METHOD` annotation to have the same effect.
* [NFC] Move HLSL shfit behavior to frontend
The HLSL bit shift behavior was implemented in constant folding which
alters the semantics of the IR. Alternatively we can implement it in
the front end, leveraging the existing OpenCL code paths.
This results in the same final IR optimization and allows reverting the
ConstantFolder and IR tests back to match LLVM 3.7.
The HLSL shift behavior's optimized behavior is verified in existing
tests like the shift-fold.hlsl test, which is unimpacted by this change.
The big motiviation for this change is heading off subtle bugs. All our
tests cover cases where the shift's size is known at compile time. In
those cases the compiler can resolve the masking behavior
automatically. We have _no_ tests, nor compiler changes that impact
shifts that aren't compile-time known.
This means that prior to this change the behavior of shifting by a
compile-time resolvable value and shifting by a non-resolvable value
likely differs. Since backends often load DXIL and treat it as LLVM IR,
this could cause concerning issues.
This handles a few last Windows fixes for LLVM tests.
* The YAML praser convertes \r to \n, resulting in repeated newlines in
YAML tests on Windows.
* The MS filesystem changes on Windows cause one of the MemoryBuffer
tests to fail. I've disabled that test on Windows.
* Because we convert many crash cases to exceptions on Windows the
GoogleTest DEATH tests fail to die on Windows.
This change addresses the same issue #4794 solves, but restricts the
change to Windows only. I'm only merging this since @python3kgae is out
and I don't really want to wait until he returns.

The initializer list goes out of scope after the expression it is used
in, so the ArrayRef points to invalid memory. This change keeps the
initialization list around so that the array ref remains valid through
the test.
* Get LLVM Unit Tests Passing
This change in conjunction with the work in #4020, will get all of the
LLVM unit tests passing. In addition to minor fixes in several of the
tests, and to the build configuration, this patch adds a new implicit
disk filesystem if the filesystem APIs are used without initializing a
PerThreadFileSystem.
The implicit filesystem is only enabled if `LLVM_INCLUDE_TEST=On`, and
it should allow the LLVM filesystem APIs to behave as LLVM tools and
tests expect them to.
* Fix windows build
* Changes to get LLVM unit tests building
This change gets the LLVM unit tests building again and running through
LIT via the `check-llvm-unit` target.
This change does not have the tests passing! Subsequent changes will
get the unit tests passing. This change also disables some tests where
the LLVM code is no longer used and making those tests work will
require substantial effort.
* Changes to get Clang unit tests building
This change gets the Clang unit tests building again and running
through LIT via the `check-clang-unit` target.
This change does not have the tests passing! Subsequent changes will
get the unit tests passing. This change also disables some tests where
the Clang code is no longer used and making those tests work will
require substantial effort.
* A few extra Windows fixes
This adds some missing APIs to the Windows Filesystem code and adds an
option to hctbuild to enable building the LLVM & Clang unit tests.
* Disable libClangFormat tests
These tests are a bit gnarly to repair... unless we really start using
the format library we probably just want to disable these tests.
Fix#30: Revert license text in banner comments to original llvm verbage
This commit removes the Microsoft-specific copyright in llvm files
and reverts the copyright wording to the original llvm wording.
We used the following method to find the files to change:
1. Find all files in DirectXShaderCompiler that are also in llvm 3.7
2. For those files that have the Microsoft-specific copyright, revert
it to the original llvm copyright as present in llvm 3.7
3. Revert the copyright in a few files that are not in llvm, but are
mostly copies of files in llvm:
lib\Transforms\Scalar\ScalarReplAggregatesHLSL.cpp
lib\Transforms\Scalar\Reg2MemHLSL.cpp
Leave the Microsoft-specific copyright header in files not present
in stock llvm:
