CLRadeonExtender Disassembler

The CLRadeonExtender provides a disassembler that can disassemble code for the Radeon GPU's based on the GCN 1.0/1.1/1.2/1.4 (AMD VEGA) architecture. Program is called clrxdisasm.

Disassembler can handle the AMD Catalyst(tm) OpenCL(tm) kernel binaries and the GalliumCompute kernel binaries. It displays instructions of the code and optionally structure of the binaries (kernels and their configuration). Output of that program can be used as input to the CLRX assembler if option '--all' will be used.

A disassembler can detect automatically binary format, bitness of the binary.

Invoking a disassembler

The clrxdisasm can be invoked in following way:

clrxdisasm [-mdcCfsHLhar?] [-g GPUDEVICE] [-a ARCH] [-t VERSION] [--metadata] [--data] [--calNotes] [--config] [--floats] [--hexcode] [--setup] [--HSAConfig] [--HSALayout] [--all] [--raw] [--gpuType=GPUDEVICE] [--arch=ARCH] [--driverVersion=VERSION] [--llvmVersion=VERSION] [--buggyFPLit] [--help] [--usage] [--version] [file...]

Program Options

Following options clrxdisasm can recognize:

• <-m>, --metadata>

  Print metadata from AMD Catalyst binaries to output. For a AMD Catalyst binaries, disassembler prints internal metadata. For a GalliumCompute binaries disassembler prints argument of the kernel and proginfo entries.

• -d, --data

  Print data section from binaries. For AMD Catalyst binaries disassembler prints global constant data, and '.data' section for particular kernel executables. For GalliumCompute binaries disassembler prints a global constant data.

• -c, --calNotes

  Print list of the ATI CAL notes and their content from AMD Catalyst binaries to output.

• -C, --config

  Print human-readable configuration instead of metadatas, headers and ATI CAL notes.

• -f, --float

  Print floating point literals in instructions if instructions accept float point values and their has a constant literal. Floating point values will be inside comment.

• -h, --hexcode

  Print hexadecimal code before disassembled instruction in comment. Hexadecimal code will be printed in 4-byte words.

• -s, --setup

  Print AMD OpenCL 2.0 kernel setup data.

• -H, --HSAConfig

  Print AMD OpenCL 2.0 kernel setup configuration as AMD HSA configuration.

• -L, --HSALayout

  Print AMD OpenCL 2.0 code like Gallium or ROCm: print text section as program code with kernel names.

• -a, --all

  Enable all options -mdcfh (except -C).

• -r, --raw

  Treat input as raw code. By default, disassembler assumes that input code is for the GCN1.0 architecture.

• -g GPUDEVICE, --gpuType=GPUDEVICE

  Choose device type. Device type name is case-insensitive. List of supported GPUs: Baffin, Bonaire, CapeVerde, Carrizo, Dummy, Ellesmere, Fiji, GFX700, GFX701, GFX801, GFX802, GFX803, GFX804, GFX900, GFX901, GFX902, GFX903, GFX904, GFX905, GFX906, GFX907, Goose, Hainan, Hawaii, Horse, Iceland, Kalindi, Mullins, Oland, Pitcairn, Polaris10, Polaris11, Polaris12, Polaris20, Polaris21, Polaris22, Raven, Spectre, Spooky, Stoney, Tahiti, Tonga, Topaz, Vega10, Vega11, Vega12 and Vega20.

• -A ARCH, --arch=ARCH

  Choose device architecture. Architecture name is case-insensitive. List of supported architectures: SI, VI, CI, VEGA, VEGA20, GFX6, GFX7, GFX8, GFX9, GFX906, GCN1.0, GCN1.1, GCN1.2, GCN1.4 and GCN1.4.1.

• -t VERSION, --driverVersion=VERSION

  Choose AMD Catalyst OpenCL driver version for which binaries are generated. Version can retrieved from clinfo program that display field 'Driver version' where version is. Version is number in that form: MajorVersion*100 + MinorVersion. Used for AMD OpenCL 2.0 binaries.

• --llvmVersion=VERSION

  Choose LLVM version that generates binaries. Version is number in that form: MajorVersion*100 + MinorVersion.

• --buggyFPLit

  Choose old and buggy floating point literals rules (to 0.1.2 version) for compatibility.

• -?, --help

  Print help and list of the options.

• --usage

  Print usage for this program

• --version

  Print version

Output

clrxdisasm prints a disassembled code to standard output and errors to standard error output. clrxdisasm returns 0 if succeeded, otherwise it returns 1 and prints the error messages to stderr

Sample usages

Following sample usages:

• clrxdisasm -aC source.clo

  Disassemble binary file source.clo. Print addresess, opcodes, metadata in human readable form.

• clrxdisasm -a source.clo

  Disassemble binary file source.clo. Print addresess, opcodes, metadata in machine readable form (enough rarely used).

• clrxdisasm -aC -t240400 source.clo

  Disassemble binary file source.clo including AMD driver version 240400. Print addresess, opcodes, metadata in human readable form.

• clrxdisasm -aCHL -t240400 source.clo

  Disassemble binary file AMD OpenCL 2.0 source.clo including AMD driver version 240400 in new HSA layout form (like ROCm). Print addresess, opcodes, metadata in human readable HSA config form.

• clrxdisasm -aC -gBonaire source.clo

  Disassemble binary file source.clo for Bonaire GPU device. It can be used while disassemblying GalliumCompute binaries. Print addresess, opcodes, metadata in human readable form.

• clrxdisasm -aC -t170000 --llvmVersion=40000 -gBonaire source.clo

  Disassemble new GalliumCompute (for new MesaOpenCL 17.0.0 or later and LLVM 4.0.0 or later) binary file source.clo for Bonaire GPU device. Print addresess, opcodes, metadata in human readable form.
