This enables LoopStrengthReduce for loops with i32 induction variables, among other optimizations. +* MC layer support was added for the experimental Zca, Zcd, Zcf, Zihintntl, Ztso, + and Zawrs extensions. +* Codegen support was added for the experimental Zca extension and for the + Zfhmin extension. +* MC layer and codegen support was added for the custom XVentanaCondOps and + XTHeadVdot extensions. +* A target feature was introduced to force-enable atomics. +* Support was added for lowering HWASAN intrinsics. +* The short forward branch optimisation beneficial to the SiFive Series 7 was + implemented. +* A Syntacore SCR1 CPU model was added. +* Various codegen improvements.
