is_breg_access_indirect(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to is_breg_access_indirect(9) from the Kernel API Manual — this is the little helper that does a vibe check on whether breg based access implies type dereference, and honestly it's giving "tiny function, big brain" energy. 💅✨

🌸 NAME 🌸

is_breg_access_indirect — check if breg based access implies type dereference. That's the mission, no cap.

🎀 SYNOPSIS 🎀

bool is_breg_access_indirect (Dwarf_Op *ops , size_t nops );

🫶 ARGUMENTS 🫶

  • ops — DWARF operations array. That's the ops pile, bestie.
  • nops — number of operations in ops. Literally how many ops are in ops.

🔥 DESCRIPTION 🔥

Okay so here's the tea: it returns true if the DWARF expression evaluates to the variable's value, so the memory access on that register needs type dereference. It returns false if the expression evaluates to the variable's address. And p.s. this is called after check_allowed_ops, so like, after that gate check this one swoops in. ✨
