[Bug]: TensileCreateLibrary prepAsm error

[xuantengh]

Describe the bug

Tensile Python script reports error when building rocBLAS 5.5.0

To Reproduce

The CMake configure command is:

CXX=$HOME/opt/rocm/5.5.0/bin/hipcc \
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DAMDGPU_TARGETS="gfx1030" \
    -DROCM_PATH=$HOME/opt/rocm/5.5.0/lib/cmake \
    -DCMAKE_MODULE_PATH=$HOME/opt/rocm/5.5.0 \
    -DCMAKE_PREFIX_PATH=$HOME/opt/rocm/5.5.0 \
    -DTensile_LOGIC=asm_full \
    -DTensile_ARCHITECTURE="gfx1030" \
    -DTensile_CODE_OBJECT_VERSION=default \
    -DTensile_LIBRARY_FORMAT=yaml \
    -DRUN_HEADER_TESTING=OFF \
    -DCPACK_SET_DESTDIR=OFF \
    -DCMAKE_INSTALL_PREFIX=$HOME/opt/rocm/5.5.0

@Huangxt57 ,
Could you please provide the following information,
Make sure that ROCm is correctly installed and to capture detailed environment information run the following command:

printf '=== environment\n' > environment.txt &&
printf '\n\n=== date\n' >> environment.txt && date >> environment.txt &&
printf '\n\n=== Linux Kernel\n' >> environment.txt && uname -a  >> environment.txt &&
printf '\n\n=== rocm-smi' >> environment.txt && rocm-smi  >> environment.txt &&
printf '\n\n' >> environment.txt && hipconfig  >> environment.txt &&
printf '\n\n=== rocminfo\n' >> environment.txt && rocminfo  >> environment.txt &&
printf '\n\n=== lspci VGA\n' >> environment.txt && lspci | grep -i vga >> environment.txt

Attach environment.txt

Also, attach the build log as well.

environment.txt
cmake.log

The necessary attachments are uploaded.

It could be resolved after I use the 5.6.0 version and specify environment variable TENSILE_ROCM_ASSEMBLER_PATH to the path of clang.

@Huangxt57 ,
I am unable to reproduce the error.

From the attached cmake.log, I see that the Tensile build script is unable to resolve the hipcc and assembler path. could you check if the valid path is set?
