2025-02-14[HLSL] Implement HLSL Aggregate splatting (#118992)Sarah Spall1-0/+1
Implement HLSL Aggregate Splat casting that handles splatting for arrays and structs, and vectors if splatting from a vec1. Closes #100609 and Closes #100619 Depends on #118842

2024-04-01[HLSL] Implement array temporary support (#79382)Chris B1-0/+1
HLSL constant sized array function parameters do not decay to pointers. Instead constant sized array types are preserved as unique types for overload resolution, template instantiation and name mangling. This implements the change by adding a new `ArrayParameterType` which represents a non-decaying `ConstantArrayType`. The new type behaves the same as `ConstantArrayType` except that it does not decay to a pointer. Values of `ConstantArrayType` in HLSL decay during overload resolution via a new `HLSLArrayRValue` cast to `ArrayParameterType`. `ArrayParamterType` values are passed indirectly by-value to functions in IR generation resulting in callee generated memcpy instructions. The behavior of HLSL function calls is documented in the [draft language specification](https://microsoft.github.io/hlsl-specs/specs/hlsl.pdf) under the Expr.Post.Call heading. Additionally the design of this implementation approach is documented in [Clang's documentation](https://clang.llvm.org/docs/HLSL/FunctionCalls.html) Resolves #70123
2024-02-15[HLSL] Vector standard conversions (#71098)Chris B1-0/+4
HLSL supports vector truncation and element conversions as part of standard conversion sequences. The vector truncation conversion is a C++ second conversion in the conversion sequence. If a vector truncation is in a conversion sequence an element conversion may occur after it before the standard C++ third conversion. Vector element conversions can be boolean conversions, floating point or integral conversions or promotions.

This patch replaces uses of StringRef::{starts,ends}with with StringRef::{starts,ends}_with for consistency with std::{string,string_view}::{starts,ends}_with in C++20. I'm planning to deprecate and eventually remove StringRef::{starts,ends}with.

2019-07-02[C++2a] Add __builtin_bit_cast, used to implement std::bit_castErik Pilkington1-0/+1
This commit adds a new builtin, __builtin_bit_cast(T, v), which performs a bit_cast from a value v to a type T. This expression can be evaluated at compile time under specific circumstances. The compile time evaluation currently doesn't support bit-fields, but I'm planning on fixing this in a follow up (some of the logic for figuring this out is in CodeGen). I'm also planning follow-ups for supporting some more esoteric types that the constexpr evaluator supports, as well as extending __builtin_memcpy constexpr evaluation to use the same infrastructure. rdar://44987528 Differential revision: https://reviews.llvm.org/D62825 llvm-svn: 364954

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+3
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. llvm-svn: 351636

This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

2016-07-28[OpenCL] Generate opaque type for sampler_t and function call for the ↵Yaxun Liu1-0/+1
initializer Currently Clang use int32 to represent sampler_t, which have been a source of issue for some backends, because in some backends sampler_t cannot be represented by int32. They have to depend on kernel argument metadata and use IPA to find the sampler arguments and global variables and transform them to target specific sampler type. This patch uses opaque pointer type opencl.sampler_t* for sampler_t. For each use of file-scope sampler variable, it generates a function call of __translate_sampler_initializer. For each initialization of function-scope sampler variable, it generates a function call of __translate_sampler_initializer. Each builtin library can implement its own __translate_sampler_initializer(). Since the real sampler type tends to be architecture dependent, allowing it to be initialized by a library function simplifies backend design. A typical implementation of __translate_sampler_initializer could be a table lookup of real sampler literal values. Since its argument is always a literal, the returned pointer is known at compile time and easily optimized to finally become some literal values directly put into image read instructions. This patch is partially based on Alexey Sotkin's work in Khronos Clang (https://github.com/KhronosGroup/SPIR/commit/3d4eec61623502fc306e8c67c9868be2b136e42b).

In {CG,}ExprConstant.cpp, we weren't treating vector splats properly. This patch makes us treat splats more properly. Additionally, this patch adds a new cast kind which allows a bool->int cast to result in -1 or 0, instead of 1 or 0 (for true and false, respectively), so we can sanely model OpenCL bool->int casts in the AST.
