Andrea Di Biagio e0900f285b [MCA] Improved cost computation for loop carried dependencies in the bottleneck analysis. ... This patch introduces a cut-off threshold for dependency edge frequences with the goal of simplifying the critical sequence computation. This patch also removes the cost normalization for loop carried dependencies. We didn't really need to artificially amplify the cost of loop-carried dependencies since it is already computed as the integral over time of the delay (in cycle). In the absence of backend stalls there is no need for computing a critical sequence. With this patch we early exit from the critical sequence computation if no bottleneck was reported during the simulation. llvm-svn: 372337		2019-09-19 16:05:11 +00:00
