STRUCT ANNOTATED_INSN_LOC(9)

💅 struct annotated_insn_loc(9) 💅

okay so bestie, this is the kernel API manual page for struct annotated_insn_loc — it's literally the location info of an instruction, and it's tiny but iconic 🎀

✨ NAME ✨

struct annotated_insn_loc — location info of instruction 🦋

✨ SYNOPSIS ✨

struct annotated_insn_loc {
    struct annotated_op_loc ops[INSN_OP_MAX];
 };

like, that's the whole thing. no cap. she's small but she's doing her job 💅

💖 Members 💖

• ops — the array of location info for both the source and target operands ✨ so yeah, each slot in ops (and there are INSN_OP_MAX of them, iykyk) holds the location deets for one operand, and you've got source side and target side covered 🫶

ngl the members section is short here — one member, one job, main character energy fr fr 👑

🌈 SEE ALSO 🌈

• Kernel file ./tools/perf/util/annotate.h — that's where this lives, go look, it's giving source of truth 💜
• struct sym_hist(9) ⭐
• struct cyc_hist(9) ⭐
• struct annotated_source(9) ⭐
• struct annotated_branch(9) ⭐
• struct annotated_op_loc(9) ⭐ — the one that actually fills up that ops array, obsessed
• struct annotated_basic_block(9) ⭐

and that's the vibe check, bestie 💖 this page came out of ./tools/perf/util in October 2026, so when you're deep in the annotate headers at 2am, know that she said exactly that 🌸🎀✨
