ニーモニックランキング

独習アセンブラ 新版 (2021) 翔泳社 pp.273-275 で/usr/bin内の実行ファイルにおける機械語の命令の出現回数を数える方法が紹介されていたので、自分の環境（Docker ubuntu:24.04）でも試してみた。 cutがうまくいかなかったので、grepで作り直した。

#!/bin/sh
 
for i in /usr/bin/*
do
  file $i | grep ELF >/dev/null && objdump -d $i -M intel
done |
  grep -oP '^\s*[0-9A-Fa-f]+:\s+(?:[0-9A-Fa-f]{2}\s+)*\K[a-zA-Z][a-zA-Z0-9_]*' |
  sort | uniq -c |
  sort -rn

#!/usr/bin/env python3
import sys
 
def main():
    entries = []
    for line in sys.stdin:
        parts = line.strip().split()
        entries.append((int(parts[0]), parts[1]))
 
    total = sum(c for c, _ in entries)
    print('Rank | Percentile | Mnemonic')
    for rank, (count, mnemonic) in enumerate(entries, start=1):
        pct = count / total * 100
        print(f'{rank} | {pct:.2f} | {mnemonic}')
 
if __name__ == '__main__':
    main()
