Heatmap collects samples grouped by buckets. The size is configurable via `--block-size`, with 64 bytes as the default (X86 cache line size). Define section utilization as the number of buckets mapped to the section with non-zero samples divided by the total number of buckets covering the section. Note that for buckets that cross section boundaries, we will attribute the utilization to the first overlapping section. Test Plan: updated heatmap-preagg.test _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
