In Verilog/SystemVerilog language, the basic type is bit or bit vector, and length is arbitrary, insert/extract bits are common features in language. Introducing corresponding intrinsics could help gradually lower it and bring more optimization opportunities in llc. Otherwise, many shift/and/or are needed to be translated and then depends on code pattern matching to recognize and optimize them. https://github.com/llvm/llvm-project/pull/79672 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
