💖 DESCRIPTION 💖

lto-dump is a tool you can use in conjunction with GCC to dump link time optimization object files. That's the whole job, and it does it beautifully. No cap. 🔥

👑 OPTIONS 👑

Every flag, in order, no skipping, we don't do that here 💅

  • -list — dumps a list of details of functions and variables. The classic. The starter pack. 🍓
  • -demangle — dumps the demangled output. Because reading mangled names is a personal attack and we don't deserve that. 😭
  • -defined-only — dumps only the defined symbols. Unbothered. Filtered. Boundaries set. 🫶
  • -print-value — dumps the initial values of the variables. Receipts! 💖
  • -name-sort — sorts the symbols alphabetically. Organized queen behavior. 🔤
  • -size-sort — sorts the symbols according to size. Big ones, little ones, all valid. 🐘🐜
  • -reverse-sort — dumps the symbols in reverse order. Main character energy: starts from the end. 💀
  • -no-sort — dumps the symbols in order of occurrence. Chaos, but make it intentional. 🌈
  • -symbol= — dumps the details of a specific symbol. Just the one. Very me-core. ⭐
  • -objects — dumps the details of LTO objects. All the objects. 💜
  • -type-stats — dumps the statistics of tree types. Numbers. Stats. We love data. 📊
  • -tree-stats — dumps the statistics of trees. Yes, more trees. No, not those trees. 🌳
  • -gimple-stats — dumps the statistics of gimple statements. Gimple! Say it with me: GIMPLE. 🧚
  • -dump-level= — for deciding the optimization level of body. You supply the value, it decides. 🤝
  • -dump-body= — dumps the specific gimple body. One body. Specifically that one. 🎯
  • -help — displays the dump tool help. When in doubt, ask for help. Literally. 🙈
