# ROCm Code Object tooling
|
||||
|
||||
ROCm compiler generated code objects (executables, object files, and shared object libraries) can be examined and code objects extracted with the following tools.
|
||||
|
||||
## URI syntax:
|
||||
|
||||
ROCm Code Objects can be listed/accessed using the following URI syntax:
|
||||
```
|
||||
code_object_uri ::== file_uri | memory_uri
|
||||
file_uri ::== file:// extract_file [ range_specifier ]
|
||||
memory_uri ::== memory:// process_id range_specifier
|
||||
range_specifier ::== [ # | ? ] offset= number & size= number
|
||||
extract_file ::== URI_ENCODED_OS_FILE_PATH
|
||||
process_id ::== DECIMAL_NUMBER
|
||||
number ::== HEX_NUMBER | DECIMAL_NUMBER | OCTAL_NUMBER
|
||||
```
|
||||
Example: file://dir1/dir2/hello_world#offset=133&size=14472
|
||||
memory://1234#offset=0x20000&size=3000
|
||||
|
||||
|
||||
## List available ROCm Code Objects: rocm-obj-ls
|
||||
|
||||
Use this tool to list available ROCm code objects. Code objects are listed using URI syntax.
|
||||
|
||||
Usage: roc-obj-ls [-v|h] executable...
|
||||
List the URIs of the code objects embedded in the specfied host executables.
|
||||
-v Verbose output (includes Entry ID)
|
||||
-h Show this help message
|
||||
|
||||
|
||||
## Extract ROCm Code Objects: rocm-obj-extract
|
||||
|
||||
Extracts available ROCm code objects from specified URI.
|
||||
|
||||
Usage: rocm-obj-extract [-o|v|h] URI...
|
||||
- URIs can be read from STDIN, one per line.
|
||||
- From the URIs specified, extracts code objects into files named: <executable_name>-[pid<number>]-offset<number>-size<number>.co
|
||||
|
||||
Options:
|
||||
-o <path> Path for output. If "-" specified, code object is printed to STDOUT.
|
||||
-v Verbose output (includes Entry ID).
|
||||
-h Show this help message
|
||||
|
||||
Note, when specifying a URI argument to roc-obj-extract, if cut and pasting the output from roc-obj-ls you need to escape the '&' character or your shell will interpret it as the option to run the command as a background process.
|
||||
As an example, if roc-obj-ls generates a URI like this ```file://my_exe#offset=24576&size=46816xxi```, you need to use the following argument to roc-obj-extract: ```file://my_exe#offset=24576\&size=46816```
|
||||
|
||||
## Examples:
|
||||
|
||||
### Dump all code objects to current directory:
|
||||
roc-obj-ls <exe> | roc-obj-extract
|
||||
|
||||
### Dump the ISA for gfx906:
|
||||
roc-obj-ls -v <exe> | grep "gfx906" | awk '{print $2}' | roc-obj-extract -o - | llvm-objdump -d - > <exe>.gfx906.isa
|
||||
|
||||
### Check the e_flags of the gfx908 code object:
|
||||
roc-obj-ls -v <exe> | grep "gfx908" | awk '{print $2}' | roc-obj-extract -o - | llvm-readelf -h - | grep Flags
|
||||
|
||||
### Disassemble the fourth code object:
|
||||
roc-obj-ls <exe> | sed -n 4p | roc-obj-extract -o - | llvm-objdump -d -
|
||||
|
||||
### Sort embedded code objects by size:
|
||||
for uri in $(roc-obj-ls <exe>); do printf "%d: %s\n" "$(roc-obj-extract -o - "$uri" | wc -c)" "$uri"; done | sort -n
|
||||
|
||||
### Compare disassembly of gfx803 and gfx900 code objects:
|
||||
dis() { roc-obj-ls -v <exe> | grep "$1" | awk '{print $2}' | roc-obj-extract -o - | llvm-objdump -d -; }
|
||||
diff <(dis gfx803) <(dis gfx900)
