Currently, kernel argument metadata is omitted unless the "-cl-kernel-arg-info" option is specified.
But according to the latest SPIR specification https://www.khronos.org/registry/spir/specs/spir_spec-1.2.pdf section 2.4, all metadata except for the kernel_arg_name nodes should be emitted, and kernel_arg_name is only emitted when "-cl-kernel-arg-info" is specified. """Kernel argument specific information is preserved using metadata objects. These objects are gen- erated for every kernel, with an exception for the kernel arg name metadata, which is generated only when the -cl-kernel-arg-info build option is specified for compilation. The metadata nodes describing the kernel argument info are in the form of a string tag, and then a list of the corresponding data for each one of the kernel’s arguments.""" This patch fixes the behavior of the option and updates the associated test cases. It is a follow up to this bug report: http://llvm.org/bugs/show_bug.cgi?id=21555 Let me know if you have questions or would like any further changes. - thanks
