[OpenCL] Add missing address spaces in IR generation of blocks Modify ObjC blocks impl wrt address spaces as follows: - keep default private address space for blocks generated as local variables (with captures); - add global address space for global block literals (no captures); - make the block invoke function and enqueue_kernel prototype with the generic AS block pointer parameter to accommodate both private and global AS cases from above; - add block handling into default AS because it's implemented as a special pointer type (BlockPointer) in the frontend and therefore it is used as a pointer everywhere. This is also needed to accommodate both private and global AS blocks for the two cases above. - removes ObjC RT specific symbols (NSConcreteStackBlock and NSConcreteGlobalBlock) in the OpenCL mode.

[OpenCL] Clean up and add missing fields for block struct 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] Change type of block pointer for OpenCL Summary: For some reason OpenCL blocks in LLVM IR are represented as function pointers. These pointers do not point to any real function and never get called. Actually they point to some structure, which in turn contains pointer to the real block invoke function. This patch changes represntation of OpenCL blocks in LLVM IR from function pointers to pointers to `%struct.__block_literal_generic`. Such representation allows to avoid unnecessary bitcasts and simplifies further processing (e.g. translation to SPIR-V ) of the module for targets which do not support function pointers.

[OpenCL] Emit enqueued block as kernel 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. Differential Revision: https://reviews.llvm.org/D38134 llvm-svn: 315804

[OpenCL] Add block argument CodeGen test r326937 ("[OpenCL] Remove block invoke function from emitted block literal struct", 2018-03-07) broke block argument handling. In particular the commit was causing a crash during code generation, see the discussion in https://reviews.llvm.org/D43783 . The offending commit has just been reverted; add a test to avoid breaking this again in the future. llvm-svn: 343583

[OpenCL] Fix assertion due to blocks A recent change caused assertion in CodeGenFunction::EmitBlockCallExpr when a block is called. There is code Func = CGM.getOpenCLRuntime().getInvokeFunction(E->getCallee()); getCalleeDecl calls Expr::getReferencedDeclOfCallee, which does not handle BlockExpr and returns nullptr, which causes isa to assert. This patch fixes that. Differential Revision: https://reviews.llvm.org/D58658 llvm-svn: 354893
