CLRadeonExtender Assembler

This is CLRadeonExtender assembler. This assembler can assemble code for all Radeon GPU's that based on the GCN1.0/1.1/1.2 architecture and it can generate AMD Catalyst OpenCL binaries and the GalliumCompute OpenCL binaries. It is compatible with GNU as and support the almost GNU as pseudo-operations (directives) including macros and repetitions.

Invoking an assembler

the clrxasm can be invoked in following way:

clrxasm [-6Sw?] [-D SYM[=VALUE]] [-I PATH] [-o OUTFILE] [-b BINFORMAT] [-g GPUDEVICE] [-A ARCH] [-t VERSION] [--defsym=SYM[=VALUE]] [--includePath=PATH] [--output OUTFILE] [--binaryFormat=BINFORMAT] [--64bit] [--gpuType=GPUDEVICE] [--arch=ARCH] [--driverVersion=VERSION] [--forceAddSymbols] [--noWarnings] [--help] [--usage] [--version] [file...]

Input

An assembler read source from many files. If no input file specified an assembler will read source from standard input.

Program options

Following options clrxasm can recognize:

  • -D SYMBOL[=VALUE], --defsym=SYMBOL[=VALUE]

    Define symbol. Value is optional and if it is not given then assembler set 0 by default. This option can be occurred many times to defining many symbols.

  • -I PATH, --includePath=PATH

    Add an include path to search path list. Assembler begins search from current directory and follows to next include paths. This option can be occurred many times to adding many include paths.

  • -o FILENAME, --output=FILENAME

    Set output file name. By default assembler write output to the 'a.out' file.

  • -b BINFORMAT, --binaryFormat=BINFORMAT

    Set output binary format. This settings can be overriden in source code. Assembler accepts following formats: 'amd', 'gallium', 'rawcode'.

  • -6, --64bit

    Enable generating of the 64-bit binaries (only for AMD catalyst format).

  • -g GPUDEVICE, --gpuType=GPUDEVICE

    Choose device type. Device type name is case-insensitive. Currently is supported: CapeVerde, Pitcairn, Tahiti, Oland, Bonaire, Spectre, Spooky, Kalindi, Hainan, Hawaii, Iceland, Tonga, Mullins, Fiji and Carrizo.

  • -A ARCH, --arch=ARCH

    Choose device architecture. Architecture name is case-insensitive. List of supported architectures: GCN1.0, GCN1.1 and GCN1.2.

  • -t VERSION, --driverVersion=VERSION

    Choose AMD Catalyst OpenCL driver version. Version can retrieved from clinfo program that display field 'Driver version' where version is. Version is number in that form: MajorVersion*100 + MinorVersion.

  • -S, --forceAddSymbols

    Add all non-local symbols to binaries. By default any assembler does not add any symbols to keep compatibility with original format.

  • -w, --noWarnings

    Do not print all warnings.

  • -?, --help

    Print help and list of the options.

  • --usage

    Print usage for this program

  • --version

    Print version

Output

An assembler generates single output binary. If no output specified an assembler will generate a.out binary file. clrxasm returns 0 if succeeded, otherwise it returns 1 and prints an error messages to stderr.
