tra added a comment. This particular change is largely cosmetic. I've just spotted this nit while I was debugging a different problem.
It's also related to module ID. We're trying to compile NCCL 2.3 with -fcuda-rdc and we were getting duplicate symbols when we tried to link multiple object files compiled from the same source file. E.g. clang++ -DPART1 -o foo-1.o foo.cu clang++ -DPART2 -o foo-2.o foo.cu ... nvlink .... The stubs generated by nvlink ended up with conflicting names (based on module ID) that were identical for all foo-*.o. It appears that clang generates ID based on the source file name only, so all foo-*.o end up with identical ID. NVCC, on the other hand, appears to generate ID based on some other factors (compiler flags? preprocessed TU source?) so each object file gets a unique ID. For now we've worked around this by renaming the source files before compilation of each part, but we will need to find a better solution. https://reviews.llvm.org/D52938 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
