Each row is one isel_diff.py campaign: every RISC-V CodeGen RUN line (plus mutants) compiled with SelectionDAG and GlobalISel. Counts are functions; "crash" counts configurations. Click "C" to compare a run with the previous run of the same label, "B" to compare with the latest main run. "Godbolt" counts findings that reproduce on Compiler Explorer trunk.

main uses the same mutation seeds every day, so its deltas come from LLVM changes. explore uses new seeds every day to find new problems; its "B" link lists what it found beyond main, and its own deltas are partly chance.
