This intrinsic was introduced by #81331, which is a lot like `llvm.readcyclecounter`. For the RISCV implementation, we rename `ReadCycleWide` pseudo to `ReadCounterWide` and make it accept two operands (the low and high parts of the counter). As for legalization and lowering parts, we reuse the code of `ISD::READCYCLECOUNTER` (make it able to handle both intrinsics). Tests using Clang builtins are runned on real hardware and it works as excepted. _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
