compilation fails with -cl-opt-disable
When compiling with -cl-opt-disable, I get the following errors (one for each kernel function):
: error: can't create dynamic relocation R_AMDGPU_REL32_LO against symbol: norm2 in readonly segment; recompile object files with -fPIC
>>> defined in /tmp/t_20283_71-5d7565.o

Need more info then this, we need to know which driver your using 1.7, is it the stock OpenCL runtime
run clinfo
G
Apologies for the missing details. I'm using GROMACS v2018, with default flags plus -cl-opt-disable (note this cab be repro-d by passing the GMX_OCL_NOOPT=1 env var to GROMACS). Admittedly, I was hoping this overrides all other command line options, including optimization options, though it may not; still, I'd hope for a more friendly error if that's the issue.
Here's the generated list of command line option (minus the -D's): -cl-opt-disable -cl-fast-relaxed-math
I'm using 1.7.1-rc5 (IIRC), here's the clinfo output:

Hi @pszi1ard,
I fixed similar issue earlier. Can you try with the newer version of compiler, which includes this commit: https://github.com/RadeonOpenCompute/clang/commit/217f7efd9759e285b74a1368dfbd054368d7d9f3#diff-6e55490bc6f998368636d91d111084a2 ?
@kzhuravl will this be in 1.7.1 (asking because I'm short on time so I'd rather wait for the release and test it).
