            Bug ID: 21555
           Summary: "-cl-kernel-arg-info" option does not work correctly
                    when compiling with spir as target
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: LLVM Codegen
          Assignee: unassignedclangbugs at nondot.org

Created attachment 13332
  --> http://llvm.org/bugs/attachment.cgi?id=13332&action=edit
with "-cl-kernel-arg-info" option

>From the spir specification section 2.4:

"""
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 argument is only mean to omit the metadata for the "kernel_arg_name" node,
yet it omits the metadata for all many of the other metadata nodes (like
"kernel_arg_type")

I attached the files add.ll and add-no-arg-info.ll that show the problem.
