It also applies to constant and private / local address spaces. I don't think those hit 4 GiB yet but it's more feasible than shared. Making address space 3 32-bit by default would make sense to me. https://github.com/llvm/llvm-project/pull/111682 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
