It went though the conversion checks but never reported an error on the clang level. The compiler then crashed in code gen. This commit fixes that. * Resolve compiler warnings on Linux and macOS (microsoft#1628) * Removed unused functions and fields * Turned off switch enumeration value not handled warnings * Fixed initialization issues * Fix modf implementation (microsoft#1630) * Fix string interning for Subobjects (microsoft#1640) * Fix string interning for Subobjects * DxilRuntimeReflection: Remove dependency on llvm/ADT/STLExtras.h - This file is meant to be included in other projects that do not include llvm headers or libs, so it must avoid those dependencies. * Avoid unnecessary strlen operations in GetSubobjectString * StringStorage/RawBytesStorage: use pair of unique_ptr and size * Change normalize implementation. (microsoft#1641) * Change normalize implementation. From a / length(a) to a * (rsqrt(dot(a))). * Make return value the first output element. (microsoft#1622) * Add DxilContainerReader and refactor PSV/RDAT into DxilContainer lib (microsoft#1642) * Fix dynamic indexed row_major matrix from cbuffer (microsoft#1643) * Fix microsoft#1629 - crash when using NonUniformResourceIndex (microsoft#1646) Fix crash caused by NonUniformSet being invalidated before use Instead of using NonUniformSet, defer lowering of NonUniformResourceIndex until last, then mark all GEPs that use the incoming value. This will mark all uses of the value used in NonUniformResourceIndex as non-uniform, including indexing that was not marked non-uniform, if it ends up being the same index. This matches the prior behavior, and avoids loss of non-unifom metadata when merging GEPs, but could be considered not quite correct, although the difference in indexing would probably not have been intentional. * Only propagate WaveSensitive when target BB not post dom current BB.

Fixes microsoft#1690 * Added a test for gather/load of textures of 16-bit types.

(microsoft#1708) * Fix crash when assigning to global matrix in compat mode (microsoft#1709) * An earlier bitcast instruction would create an unused GEP instruction referencing the matrix, which the matrix lowering code couldn't handle. Removed that GEP. * A special case for single-index matrix access was probably meant to catch `m._11` and assumed a value type of float, but it also applied to the first subscript of `m[0][0]`, which returns `floatn`, hence a crash due to mismatched types. The condition was updated to test for non-vector values. * Better support for D3D12_SHADER_DESC reflection. (microsoft#1704) Implemented filling out fields related to shader stage properties. * Fixed crash when static methods are used. (microsoft#1714) We were unconditionally trying to manipulate the `this` pointer. Also added a simple test. * Changed cbuffer-promoted global vars to have external linkage as to not have initializers (microsoft#1713) Per LLVM rules, globals must be initialized unless they have external linkage. It makes sense to consider constant buffer values as having external linkage, since they are "linked in" by the application, so this change: * Changes CBuffer globals to have external linkage and no initializer * Fixes a few cases not handling the lack of initializers properly * Fixes some tests which were testing for initialization * Added a test for non-initialization of cbuffer-promoted globals * Disable quick-test/d3dreflect/lib_hs_export1.hlsl (microsoft#1680) - this test, along with lib_hs_shaders_only.hlsl indicate a flaky bug in the compiler that still needs investigation. * Fix assert following reflection changes. (microsoft#1717) DxilModule::GetTessellatorPartitioning didn't follow the model of other methods of returning Undefined when it does not apply to the shader stage and would assert. * Support for barycentric tests. Note that this is not the complete implementation as there will be tiers introduced for barycentrics support for preserving provoking vertex. The current test only tests SV_Barycentrics value. * Fix crash when casting structs with identical layout (microsoft#1718) * Add an error when bitfields are used. (microsoft#1719) * Fix implicit unique_ptr to bool conversion error when compiling with GCC. (microsoft#1720) * [spirv] Add support for VK_EXT_scalar_block_layout (microsoft#1716) Ref: KhronosGroup/Vulkan-Docs#854 * Added support for pre-SM5.1 resource allocation algorithm (microsoft#1687) Added front-end `-flegacy-resource-reservation` to control behavior (added automatically for SM <= 5.0) Added an error for unbounded resources used with `-flegacy-resource-reservation` Added a mechanism for `DxilModule` to preserve intermediate options during its passes but not in the final DXIL Changed `HLModule` to not remove unreferenced `DxilResources` but rather make their symbol UndefValue Fixed assumptions of `DxilResources` having a valid `GlobalVariable` Added reserved resource range gather pass before elimination of unused resources (if SM <= 5.0) Changed resource allocation to account for reserved ranges * Mark built-in types as 'final' to prevent inheritance. (microsoft#1726) * Barycentric test update; Add RawBuffer Load/Store HLK test entries (microsoft#1727) Add ExecutionTest / HLK test entries for testing RawBuffer Load/Store Modify HLSL for Barycentric test * Skip external libraries if they are already included in parent project (microsoft#1728) * Fix row_major being lost through typedefs. (microsoft#1723) The code attempted to cast a QualType to an AttributedType, which would fail if it was in fact a TypedefType. Better use the existing helper function we have. * [spirv] '++' and '--' for RWTextures/RWBuffers. (microsoft#1731) * [spirv] Fix Linux/macOS build. (microsoft#1735) Fixed ternary op ambiguity. * Remove use of `NoSerializeHeapMalloc` mem manager. (microsoft#1729) It was done to improve the compile time, but it does not seem to be better. The use of `HEAP_NO_SERIALIZE` turns off the low-fragmenataion-heap, which is what we want for this application. See microsoft#1712 for a discussion. * [spirv] Support non-fp MAD intrinsic function. (microsoft#1730) * Fix CompileWhenNoMemThenOOM test failure (microsoft#1747) Workaround a regression in the VC++ STL implementation causing the std::bad_alloc to happen in a nothrow context, and re-enabled the test on appveyor. * Prevent texture of structs/matrices/arrays, and don't crash (microsoft#1744) * Add a diagnostic error for non-scalar/vector texel types * Harden semantic analysis logic against unexpected types * Skip inserting redundant phi nodes on struct type (microsoft#1748) * Change in-memory representation of bool vectors to use i32's (microsoft#1742) This change fixes an inconsistency between scalar and vector bools, where the formers were stored as i32s in memory (as opposed to i1s in registers) while the latter remained <n x i1>s. This lead to a number of crashes in more complex bool scenarios where scalar and vector element types were expected to match. The solution is to extend Clang's strategy for scalar bools to vector of bools. Clang relies on three key functions to deal with differences between register and memory type representations which are special-cased for bools and now also for bool vectors. Several HLSL code additions did not properly leverage those functions and this was addressed wherever possible, in some cases removing the need for special cases for bools. To deal with matrices, a similar concept of register/memory representation was introduced in the matrix lowering code and the lowering passes were updated accordingly. * Fix use-after-free in parameter SROA (microsoft#1746) The parameter SROA's LowerMemcpy function deletes the memcpy and bitcast instructions after it has processed them. However, higher up the stack we created an IRBuilder pointing to the first non-alloca instruction, which happens to be the bitcast being deleted. Hence any further use of that IRBuilder will crash. The solution is to delay creating the IRBuilder until after LowerMemcpy, since the rest of the code is well-behaved with respect to instruction deletion (ie it defers them to the end). * Revert "Skip inserting redundant phi nodes on struct type (microsoft#1748)" (microsoft#1755) This reverts commit 545bf5e. * Fix invalid CmpEQ(%bool,0) for converting bools (microsoft#1756) The matrix lowering code special-cased bools and converted from i32s using CmpEQ(%bool,0) instead of CmpNE(%bool,0) in a few places. This change fixes it, where possible by leveraging MemToReg to remove the special cases. * Fix SROA bug when lowering a memcpy from a cbuffer There was already code to detect memcpy with cbuffer sources, but they only accounted for one level of GEP indirection. In the presence of complex nested structs and arrays, this might not be the case, so I extended it to support arbitrary GEP nesting. * Fix SROA for StreamOutput failing based on argument processing order (microsoft#1765) When SROA processes `StreamOutput<T>.Append`, it introduces a local variable for each value being appended, but the data might either be the original `T`, or its SROA'd version (if its argument is a parameter of the enclosing function that has already been processed by the SROA pass). There was already code handling this, but it didn't correctly detect whether the data had already been SROA'd or not. Also added some regression tests. * Created custom unroll pass to optionally include certain exit blocks. (microsoft#1752) * Update dxexp for newer shader models and features (microsoft#1762) * [spirv] Update Spriv-tools and Spriv-Headers (microsoft#1764) * Update spirv-tools and spirv-headers. Update the submodules. There is no particular commit that is needed, but it is good to not fall too far behind. * Remove AtomicCounter bit on atomic operations. The bit is ignored in the vulkan environment. It does nothing. * Update tests. * [linux-port] Fix linux build break. (microsoft#1767) * Fix a potential bug in dynamic structbuf indexing (microsoft#1754) This was found by code inspection. When GEPs containing dynamic indices are translated into structbuf offsets, the logic for computing field offsets did not take data layout into account. This might however be dead code since in all of our tests plus a few custom ones I wrote, nested GEPs where not merged, so the GEP for accessing struct fields only contained constant indices (because the field name is known at compile-time), hence we would never go down that branch. But better safe than sorry. Also consolidated some duplicate code for dealing with sequence types.

Uh oh!

TextureGather and TextureGatherCmp are missing f16 and i16 return type #739
