ClrxDisasm
The CLRadeonExtender provides a disassembler that can disassemble code
for the Radeon GPU's based on the GCN 1.0/1.1/1.2 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.
The clrxdisasm
can be invoked in following way:
clrxdisasm [-mdcCfhar?] [-g GPUDEVICE] [-a ARCH] [-t VERSION] [--metadata] [--data] [--calNotes] [--config] [--floats] [--hexcode] [--all] [--raw] [--gpuType=GPUDEVICE] [--arch=ARCH] [--driverVersion=VERSION] [--buggyFPLit] [--help] [--usage] [--version] [file...]
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.
-
-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. Currently is supported: CapeVerde, Pitcairn, Tahiti, Oland, Bonaire, Spectre, Spooky, Kalindi, Hainan, Hawaii, Iceland, Tonga, Mullins, Fiji, Carrizo, Dummy, Goose, Horse, Stoney, Ellesmere, and Baffin.
-
-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 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.
-
--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
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 an error messages to stderr
Below is sample usage of the clrxdisasm
:
clrxdisasm -a DCT.amd.0
