Sparc instructions have well-defined formats, you should rarely need to use `InstSP` as the base class, if ever. `0b00010110001` should be broken down into `fcn=0b00010` (or decimal equivalent) and `op3=0b110001`. `F3_1` looks the most appropriate base class of all existing classes, but it may also make sense to introduce a new class for this kind of instructions. https://github.com/llvm/llvm-project/pull/138400 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
