🎀 NAME 🎀

hist_entry__get_data_type — find data type for given hist entry

🦋 SYNOPSIS 🦋

struct annotated_data_type * hist_entry__get_data_type (struct
       hist_entry *he );

🌸 ARGUMENTS 🌸

• he — the hist entry, aka the main character of this whole lookup. 💫

💜 DESCRIPTION 💜

Here's the tea: this function is a two-step situation, and it absolutely eats. 🍴

First, it annotates the instruction at he->ip and extracts register and offset info from it. Then it searches the DWARF debug info to get a variable and type information using the address, register, and offset. it's giving forensic fangirl behavior, and honestly? iconic. 🔥
