How to use hcc_hsail in Rocm 1.3

[bshaozi]

I had compiled my code successful and run correctly in rocm 1.2 envrionment(Kaveri).
But after I update the rocm to 1.3, I found it seems the hcc_hsail had been deprecated.
So, I use '/opt/rocm/hcc/' instead of /opt/rocm/hcc-hsail/. (for instance , use /opt/rocm/hcc/bin/hcc /opt/rocm/hcc/bin/hcc-config --cxxflags --ldflags -I /opt/rocm/hcc/include/ xxx.cpp -o xxx to compile). It compiles successful.
But it returns error when running.follows is the error information.

HCC STATUS_CHECK Error: HSA_STATUS_ERROR_INCOMPATIBLE_ARGUMENTS (0x100d) at file:/home/scchan/code/github/radeonopencompute/hcc.1.3/hcc/lib/hsa/mcwamp_hsa.cpp line:2504

Abortado (`core' generado)

How can I compile my code in Kaveri envrionment with rocm 1.3?

could you try add "--amdgpu-target=AMD:AMDGPU:8:0:1" in your compile option? The default compiler backend now generates GCN instructions instead of HSAIL by default, and --amdgpu-target= let's you specify GCN ISA for your APU or dGPU.

Thank you for the reply. I had added the '--amdgpu-target=AMD:AMDGPU:8:0:1' in my compile option. But when I run the program, it still crash and return error information as follows:

HCC STATUS_CHECK Error: HSA_STATUS_ERROR_INCOMPATIBLE_ARGUMENTS (0x100d) at file:/home/scchan/code/github/radeonopencompute/hcc.1.3/hcc/lib/hsa/mcwamp_hsa.cpp line:2504

Aborted (core dumped)

Follows is my compile command(in ROCM 1.3) ,it doesn't work:
/opt/rocm/hcc/bin/hcc /opt/rocm/hcc/bin/hcc-config --cxxflags --ldflags --amdgpu-target=AMD:AMDGPU:8:0:1 xxx.cpp -o xxx

Before I update ROCM to 1.3. My compile command as follows and it works well:
/opt/rocm/hcc-hsail/bin/hcc /opt/rocm/hcc-hsail/bin/hcc-config --cxxflags --ldflags -I /opt/rocm/hcc-hsail/include/ xxx.cpp -o xxx

What should I do to fix it?

Thanks.

I add '--amdgpu-target=AMD:AMDGPU:7:0:0' instead of '--amdgpu-target=AMD:AMDGPU:8:0:1.
It works fine.

Thanks again!
