map__rip_2objdump(9)

✨ map__rip_2objdump ✨

okay so real talk bestie, we're deep in the Kernel API Manual today and this one is a little baby function that does exactly one (1) glow-up: it takes a symbol start address and turns it into the kind of address objdump actually understands. it's giving translator era 💅

---

🎀 NAME 🎀

map__rip_2objdump — convert symbol start address to objdump address.

like, literally just a glow-up service for addresses. no cap. ✨

---

🦋 SYNOPSIS 🦋

u64 map__rip_2objdump (const struct map *map , u64 rip );

she takes two things and gives you back a u64, that's the whole vibe 🫶

---

🌸 ARGUMENTS 🌸

• map — memory map. the whole memory map, bestie. she needs the context, she's not doing guesswork 🙈
• rip — symbol start address. the address you're trying to translate, the main character of this operation 👑

---

💖 DESCRIPTION 💖

okay so here's the tea, and it's actually important so listen up 🍓

objdump wants/reports absolute IPs for ET_EXEC, and RIPs for ET_DYN. so depending on what kind of binary you're dealing with, objdump is speaking a different dialect and someone has to translate. that someone is this function. she's bilingual, we stan 🌈

also, map->dso->adjust_symbols==1 for ET_EXEC-like cases — except ET_REL, which is relative to section start. so like, ET_REL is the exception, the one who refuses to follow the dress code 💀 keep that straight or you'll get nonsense addresses and then you'll be sad, and i don't want that for you 😭

no fr, the ET_REL exception is not a vibe-check-optional detail. relative to section start, periodt.

---

⭐ RETURN ⭐

Address suitable for passing to "objdump --start-address="

that's it. that's the return value. she hands you back something and you go plug it straight into "objdump --start-address=" and it just works 🧚 obsessed

so yeah, that's map__rip_2objdump from the ./tools/perf/util directory, October 2026 era — go forth, translate your addresses, and slay 💜🎀✨
