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
