1. Add ResourceToHandle pass to lower resource to handle.
2. Don't performPromotion in SROA_HLSL.
3. Add Option support for DynamicIndexingVectorToArray.
4. Fix bug in GetPassOption.
5. Replace GEP ptr, 0 with ptr in DynamicIndexingVectorToArray::ReplaceStaticIndexingOnVector.
6. Run mem2reg before DxilGenerationPass.
7.Legalize EvalOperations before change vector to array.
This commit adds a new pass to hoist arrays from local to global scope
when the array only contains constant values. A local array will use
alloca and stores for initialization, but a global array uses a global
variable with a constant initializer.
The idea is that a global array with constant initializer will allow the
backend compilers to produce better code because it is much easier to see
that the array is fully constant.
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:

This commit adds initial support for extension intrinsics and defines, including:
-Support for recognizing hlsl extensions as new intrinsic functions.
-Support for requesting lowering of extensions.
-Support for preserving semantic defines.
-Support for validating semantic defines.
This commit adds support for hlsl extensions in the form of additional
intrisic functions and semantic defines.
We now allow a dxcompiler instance to register that it can handle
additional intrinsic functions beyond the standard hlsl intrinsics. These
new intrinsics are called extensions. For each extension, the compiler
supplies a lowering strategy that is used by the dxcompiler to translate
from the source level intrinsic to a high-level dxil intrinsic.
We initially support the two lowering strategies: replicate and pack.
The replicate strategy will scalarize the vector elements in the call
and replicate the function call once for each element in the vector.
The pack strategy changes the vector arguments into literal struct
arguments.
We also now include support for "semantic defines". A semantic define is
a source level define whose value is preserved in the final dxil as
metatdata. The source level define can come as either a #define in
the hlsl source or a /D define from the command line.
We provide a hook to validate that a semantic define has a legal value
(for example to ensure that the value is an integer). Validation failures
can produce warnings and errors that will be emitted through the standard
clang diagnostic mechanism.
This code was originally written by marcelolr and modified by dmpots to
support packed lowering of intriniscs and validation of semantic defines.
