* [OpenCL] Fix layering violation by getOpenCLTypeAddrSpaceSven van Haastregt2017-12-061-3/+3
| | | | | | | | | | | | | Commit 7ac28eb0a5 / r310911 ("[OpenCL] Allow targets to select address space per type", 2017-08-15) made Basic depend on AST, introducing a circular dependency. Break this dependency by adding the OpenCLTypeKind enum in Basic and map from AST types to this enum in ASTContext.

* [OpenCL] Emit enqueued block as kernelYaxun Liu2017-10-141-0/+36
| | | | | | | | | | | | | | | | | | In OpenCL the kernel function and non-kernel function has different calling conventions. For certain targets they have different argument ABIs. Also kernels have special function attributes and metadata for runtime to launch them. The blocks passed to enqueue_kernel is supposed to be executed as kernels. As such, the block invoke function should be emitted as kernel with proper calling convention and argument ABI. This patch emits enqueued block as kernel. If a block is both called directly and passed to enqueue_kernel, separate functions will be generated.

* [OpenCL] Clean up and add missing fields for block structYaxun Liu2017-10-041-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently block is translated to a structure equivalent to struct Block { void *isa; int flags; int reserved; void *invoke; void *descriptor; }; Except invoke, which is the pointer to the block invoke function, all other fields are useless for OpenCL, which clutter the IR and also waste memory since the block struct is passed to the block invoke function as argument. On the other hand, the size and alignment of the block struct is not stored in the struct, which causes difficulty to implement __enqueue_kernel as library function, since the library function needs to know the size and alignment of the argument which needs to be passed to the kernel. This patch removes the useless fields from the block struct and adds size and align fields. The equivalent block struct will become struct Block { int size; int align; generic void *invoke; /* custom fields */ }; It also changes the pointer to the invoke function to be a generic pointer since the address space of a function may not be private on certain targets.

* [OpenCL] Fix size of image typeYaxun Liu2016-08-031-2/+2
| | | | | | | | | | The size of image type is reported incorrectly as size of a pointer to address space 0, which causes error when casting image type to pointers by __builtin_astype. The fix is to get image address space from TargetInfo then report the size accordingly.

* [OpenCL] Generate opaque type for sampler_t and function call for the ↵Yaxun Liu2016-07-281-1/+10
| | | | | | | | | | | | | | | | 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).

* [OpenCL] Complete image types support.Alexey Bader2016-04-081-39/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I. Current implementation of images is not conformant to spec in the following points: 1. It makes no distinction with respect to access qualifiers and therefore allows to use images with different access type interchangeably. The following code would compile just fine: void write_image(write_only image2d_t img); kernel void foo(read_only image2d_t img) { write_image(img); } // Accepted code which is disallowed according to s6.13.14. 2. It discards access qualifier on generated code, which leads to generated code for the above example: call void @write_image(%opencl.image2d_t* %img); In OpenCL2.0 however we can have different calls into write_image with read_only and wite_only images. Also generally following compiler steps have no easy way to take different path depending on the image access: linking to the right implementation of image types, performing IR opts and backend codegen differently. 3. Image types are language keywords and can't be redeclared s6.1.9, which can happen currently as they are just typedef names. 4. Default access qualifier read_only is to be added if not provided explicitly. II. This patch corrects the above points as follows: 1. All images are encapsulated into a separate .def file that is inserted in different points where image handling is required. This avoid a lot of code repetition as all images are handled the same way in the code with no distinction of their exact type. 2. The Cartesian product of image types and image access qualifiers is added to the builtin types. This simplifies a lot handling of access type mismatch as no operations are allowed by default on distinct Builtin types. Also spec intended access qualifier as special type qualifier that are combined with an image type to form a distinct type (see statement above - images can't be created w/o access qualifiers). 3. Improves testing of images in Clang. Author: Anastasia Stulova Reviewers: bader, mgrang. Subscribers: pxli168, pekka.jaaskelainen, yaxunl.
