The RISC-V specification does not take a hard stance on non-conforming extensions. It should not be consider "abusing". Whether a non-concforming extensions is allowed is up to indvidual platform requirements. We have discussed in the past about taking patches for the T-Head 0.7 vector extension. I think we were willing to take it if there was a promise of continued maintenance. https://github.com/llvm/llvm-project/pull/133031 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
