New Revision: 274540
URL: http://llvm.org/viewvc/llvm-project?rev=274540&view=rev
Log:
[OpenCL] An implementation of device side enqueue (DSE) from OpenCL v2.0 s6.13.17.
- Added new Builtins: enqueue_kernel, get_kernel_work_group_size
and get_kernel_preferred_work_group_size_multiple.
These Builtins use custom check to diagnose parameters of the passed Blocks
i. e. variable number of 'local void*' type params, and check different
overloads specified in Table 6.31 of OpenCL v2.0.
- IR is generated as an internal library call for each OpenCL Builtin,
reusing ObjC Block implementation.
