After upgrading the rocm stack from 2.7 to version 2.9, opencl applications exit abnormally with an assertion failure in llvm-roc. The 2.7 rocm stack did not exhibit this behaviour. Reproducible: Always Steps to Reproduce: 1. install the 2.9 rocm stack 2. execute an opencl application (e.g., ``clinfo``). Actual Results: The following error message is printed to screen: clinfo: /var/tmp/portage/sys-devel/llvm-roc-2.9.0/work/llvm-roc-ocl-2.9.0/include/llvm/Support/CommandLine.h:813: void llvm::cl::parser<DataType>::addLiteralOption(llvm::StringRef, const DT&, llvm::StringRef) [with DT = llvm::FunctionPass* (*)(); DataType = llvm::FunctionPass* (*)()]: Assertion `findOption(Name) == Values.size() && "Option already exists!"' failed. [1] 47569 abort (core dumped) clinfo Expected Results: Application executing successfully. Vanilla linux kernel 5.3.5, GPU is an AMD radeon rx 570.
Can you please report this issue upstream? Unfortunately, I can't reproduce it :(
I can do that. Could you tell me which is the rocm repo corresponding to the gentoo llvm-roc package?
