rv64im_min_hot_report.nx

rv64im_min_hot_report.nx -- silicon-feedback loop closure. Takes a sim that has run with per-PC cycle attribution on + the kernel ELF byte buffer; produces: 1. Top-N hot functions by cycle count (function name + cycles + % of total) 2. A silicon-acceleration candidate list -- one entry per hot function with a proposed silicon instruction add + an estimated ROI score (cycle savings / silicon gate cost) Compositional: stitches together rv64im_min_sim (per-PC cycle attribution, commit 4365e77) + rv64im_min_elf_loader (loaded the kernel into sim mem) + rv64im_min_symtab (parsed FUNC symbols from .symtab) This is the FIRST measurement-driven silicon-design-decision tool in the Nishi stack. Per [[feedback-honest-perf-verdict]]: silicon instruction additions need cycle evidence per function, not guesses. This is the producer. Per ZERO_TO_ADVANCED.md M3: "first silicon-feedback-informed spec edit" is the next milestone that uses this report's output to modify rv64im_min_target_spec.md with one or more new MUST/SHOULD instructions. Status: SEED. 2026-05-26. Reports + candidate-list shape; the silicon-cost estimator + per-instruction ROI scoring are hand-curated today; future commits learn the cost model from nishi-synth gate-count data.
