                                            - can be single or multiple target devices.

                                            Deprecated notation that is still supported:

                                            - can be single target device.

  -o <filename>                             Optional output file name.
                                            Must not be used with:

                                            Default is input file's base name.
                                            This base name will be used for all output files.
                                            For single target device proper suffixes (describing file formats)
                                            will be added automatically.

  -32                                       Forces target architecture to 32-bit pointers.
                                            Default pointer size is inherited from
                                            ocloc's pointer size.
                                            This option is exclusive with -64.

                                            for details on available internal options.
                                            You also may provide explicit --help to inquire
                                            information about option, mentioned in -options

  -llvm_text                                Forces intermediate representation (IR) format
                                            to human-readable LLVM IR (.ll).
                                            This option affects only output files
                                            and should not be used in combination with
                                            '-llvm_input' option.
                                            Default IR is spirV.
                                            This option is exclusive with -spirv_input.
                                            This option is exclusive with -llvm_input.

  -llvm_input                               Indicates that input file is an llvm binary.
                                            Default is OpenCL C kernel language.
                                            This option is exclusive with -spirv_input.
                                            This option is exclusive with -llvm_text.

                                            This option is exclusive with -llvm_input.
                                            This option is exclusive with -llvm_text.

  -options_name                             Will add suffix to output files.
                                            This suffix will be generated based on input
                                            options (useful when rebuilding with different
                                            set of options so that results won't get
                                            overwritten).
                                            This suffix is added always as the last part
                                            of the filename (even after file's extension).
                                            It does not affect '--output' parameter and can
                                            be used along with it ('--output' parameter
                                            defines the base name - i.e. prefix).

  -force_stos_opt                           Will forcibly enable stateless to stateful optimization,
                                            i.e. skip "-cl-intel-greater-than-4GB-buffer-required".

  -q                                        Will silence output messages (except errors).

  -qq                                       Will silence most of output messages.

  -v                                        Verbose mode.

  -spv_only                                 Will generate only spirV file.

  -cpp_file                                 Will generate c++ file with C-array
                                            containing Intel Compute device binary.

  -gen_file                                 Will generate gen file.

  -output_no_suffix                         Prevents ocloc from adding family name suffix.

  --help                                    Print this usage message.

  -revision_id <revision_id>                Target stepping. Can be decimal or hexadecimal value.

  -exclude_ir                               Excludes IR from the output binary file.

                                            --format patchtokens - Enforce generating patchtokens (legacy) binary.

  -stateful_address_mode                    Enforce given addressing mode. The possible values are:
                                            -stateful_address_mode bindful - enforce generating in bindful mode
                                            -stateful_address_mode bindless - enforce generating in bindless mode
                                            -stateful_address_mode default - default mode
                                            not defined: default mode.

  -heapless_mode                            Enforce heapless mode for the binary. The possible values are:
                                            -heapless_mode enable  - enforce generating in heapless mode
                                            -heapless_mode disable - enforce generating in heapful mode
                                            -heapless_mode default - default mode for current platform

  -config                                   Target hardware info config for a single device,
                                            e.g 1x4x8.
