How to unwrap .dat files to examine assembly?

[mysoreanoop]

When running hipblaslt-bench, I am able to observe certain kernels being launched like named below. I want to examine the corresponding assembly code. When I grep for this string, I see it appearing in hipblaslt/build/release/Tensile/library/*.dat file. How can I unwrap the assembly from there? If not, is there any other way I can get the assembly execution trace?

I see the associated .co file with the same file name. Is there a way to disassemble it?

Hi @mysoreanoop, you can use llvm-objdump to examine the assembly code associated with a .co file. For example,

/opt/rocm/llvm/bin/llvm-objdump --disassemble <.co file>

For more information on this, you can reference the documentation at llvm-objdump.

/opt/rocm/llvm/bin/llvm-objdump: error: '../../Tensile/library/TensileLibrary_BB_BB_HA_Bias_SAV_Type_BB_HPA_Contraction_l_Alik_Bljk_Cijk_Dijk_gfx90a.co': The file was not recognized as a valid object file

I tried it with various .co files. This is also what was selected when I invoked hipblaslt-bench.
