💖 dwarf_frame_alloc_reg(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the totally iconic little page all about dwarf_frame_alloc_reg, and honestly? it's a vibe. 🦋

✨ NAME ✨

dwarf_frame_alloc_reg — allocate memory for a DWARF register 🎀

---

✨ SYNOPSIS ✨

struct dwarf_reg * dwarf_frame_alloc_reg (struct dwarf_frame *frame ,
unsigned int reg_num );

---

🌸 ARGUMENTS 🌸

• frame — the DWARF frame whose list of registers we insert on 💅
• reg_num — the register number, like, the actual number of the register ✨

---

💜 DESCRIPTION 💜

so here's the tea, bestie: this function allocates space for a dwarf reg — from dwarf_reg_pool, no cap — and initialises it, then inserts it onto the (unsorted) linked-list of dwarf registers for frame. it's giving "new kid joins the group chat, no particular order." 🙈

and then it returns the initialised DWARF reg. that's it, that's the whole slay. 🔥
