Geza Lore	aa9cde22c8	Use SIMD intrinsics to render VCD traces (#2289) ... Use SIMD intrinsics to render VCD traces. I have measured 10-40% single threaded performance increase with VCD tracing on SweRV EH1 and lowRISC Ibex using SSE2 intrinsics to render the trace. Also helps a tiny bit with FST, but now almost all of the FST overhead is in the FST library. I have reworked the tracing routines to use more precisely sized arguments. The nice thing about this is that the performance without the intrinsics is pretty much the same as it was before, as we do at most 2x as much work as necessary, but in exchange there are no data dependent branches at all.	2020-04-30 00:09:09 +01:00
