👑 OPTIONS 👑

okay here's the whole menu, no skipping, we're listing every single one because we're thorough queens:

• -list — dumps a whole list of details about functions and variables. the main-character move ✨
• -demangle — dumps the demangled output, so your eyes don't have to decode the mangled nonsense 😭
• -defined-only — only dumps the symbols that are defined. we're not doing undefined behavior of the symbol kind today 💀
• -print-value — dumps the initial values of the variables. the origin story, if you will 🌱
• -name-sort — sorts the symbols alphabetically 📖
• -size-sort — sorts the symbols according to size 📏
• -reverse-sort — dumps the symbols in reverse order 🙃
• -no-sort — dumps the symbols in order of occurrence, i.e. no sorting, just vibes in their natural state 🌈
• -symbol= — dumps the details of a specific symbol. pick your fave and obsess 🎯
• -objects — dumps the details of LTO objects 📦
• -type-stats — dumps the statistics of tree types 🌳
• -tree-stats — dumps the statistics of trees. yes, more trees. it's giving forest 🌲
• -gimple-stats — dumps the statistics of gimple statements 🧮
• -dump-level= — for deciding the optimization level of body 🎚️
• -dump-body= — dumps the specific gimple body 🫀
• -help — displays the dump tool help. when in doubt, ask for help, we love a self-aware icon 🆘
