💖 DESCRIPTION 💖

lto-dump is the tool you can use alongside GCC to dump link time optimization object files. that's literally the vibe. you hand her an LTO object file, she tells you what's inside. iykyk. 🦋

🎀 OPTIONS 🎀

every single one, no skipping, we don't do that here:

• -list — dumps a whole list of details about functions and variables. the full rundown, bestie.
• -demangle — dumps the demangled output. because reading mangled names is giving headache energy and we do not have the time.
• -defined-only — dumps only the defined symbols. if it's not defined, she's not interested, periodt.
• -print-value — dumps the initial values of the variables. the "what did you come into this world holding" moment. 🌱
• -name-sort — sorts the symbols alphabetically. so organized. so A-to-Z coded.
• -size-sort — sorts the symbols according to size. biggest divas first (or whatever, she's sorting by size, that's the fact).
• -reverse-sort — dumps the symbols in reverse order. flip it and reverse it. 🔄
• -no-sort — dumps the symbols in order of occurrence. no reordering, just as they showed up. au naturel. ✨
• -symbol= — dumps the details of a specific symbol. put the one you want after the =. 🎯
• -objects — dumps the details of the LTO objects. the objects themselves get their moment.
• -type-stats — dumps the statistics of tree types. numbers!! stats!! we love data. 📊
• -tree-stats — dumps the statistics of trees. yes, another stats one, she's thorough.
• -gimple-stats — dumps the statistics of gimple statements. gimple gets stats too, obviously. 💀
• -dump-level= — for deciding the optimization level of body. you tell her the level after the =.
• -dump-body= — dumps the specific gimple body. name the one you want after the =. 🫶
• -help — displays the dump tool help. when in doubt, ask the tool herself.
