void OfflineCompiler::printUsage() {
argHelper->printf(R"===(Compiles input file to Intel Compute GPU device binary (*.bin).
Additionally, outputs intermediate representation (e.g. spirV).
Different input and intermediate file formats are available.
Usage: ocloc [compile] -file <filename> -device <device_type> [-output <filename>] [-out_dir <output_dir>] [-options <options>] [-32|-64] [-internal_options <options>] [-llvm_text|-llvm_input|-spirv_input] [-options_name] [-q] [-cpp_file] [-output_no_suffix] [--help]
-file <filename> The input file to be compiled
(by default input source format is
OpenCL C kernel language).
-device <device_type> Target device.
<device_type> can be: %s, %s - can be single or multiple target devices.
If multiple target devices are provided, ocloc
will compile for each of these targets and will
create a fatbinary archive that contains all of
device binaries produced this way.
Supported -device patterns examples:
-device skl ; will compile 1 target
-device skl,icllp ; will compile 2 targets
-device skl-icllp ; will compile all targets
in range (inclusive)
-device skl- ; will compile all targets
newer/same as provided
-device -skl ; will compile all targets
older/same as provided
-device gen9 ; will compile all targets
matching the same gen
-device gen9-gen11 ; will compile all targets
in range (inclusive)
-device gen9- ; will compile all targets
newer/same as provided
-device -gen9 ; will compile all targets
older/same as provided
-device * ; will compile all targets
known to ocloc
-output <filename> Optional output file base name.
Default is input file's base name.
This base name will be used for all output
files. Proper sufixes (describing file formats)
will be added automatically.
-out_dir <output_dir> Optional output directory.
Default is current working directory.
-options <options> Optional OpenCL C compilation options
as defined by OpenCL specification.
Special options for Vector Compute:
-vc-codegen <vc options> compile from SPIRV
-cmc <cm-options> compile from CM sources
-32 Forces target architecture to 32-bit pointers.
Default pointer size is inherited from
ocloc's pointer size.
This option is exclusive with -64.
-64 Forces target architecture to 64-bit pointers.
Default pointer size is inherited from
ocloc's pointer size.
This option is exclusive with -32.
-internal_options <options> Optional compiler internal options
as defined by compilers used underneath.
Check intel-graphics-compiler (IGC) project
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.
-spirv_input Indicates that input file is a spirV binary.
Default is OpenCL C kernel language format.
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 most of output messages.
-spv_only Will generate only spirV file.
-cpp_file Will generate c++ file with C-array
containing Intel Compute device binary.
-output_no_suffix Prevents ocloc from adding family name suffix.
--help Print this usage message.
-revision_id <revision_id> Target stepping.
Examples :
Compile file to Intel Compute GPU device binary (out = source_file_Gen9core.bin)
ocloc -file source_file.cl -device skl
)===",

NEO::getDevicesFamilies().c_str());
