annotate_get_basic_blocks(9)

✨ NAME ✨

okay so bestie, welcome to annotate_get_basic_blocks(9) from the Kernel API Manual — literally the function for Get basic blocks for given address range. no cap, that's the whole name. 🎀

🎀 SYNOPSIS 🎀

int annotate_get_basic_blocks (struct symbol *sym , s64 src , s64 dst ,
       struct list_head *head );

🌸 ARGUMENTS 🌸

• sym — symbol to annotate. main character energy. 🧚
• src — source address. where the journey starts. ✨
• dst — destination address. where we're headed. 🦋
• head — list head to save basic blocks. the collection point, periodt. 💅

🦋 DESCRIPTION 🦋

okay so here's the tea, bestie: this function traverses disasm_lines from src to dst and saves them in a list of annotated_basic_block to head. It uses BFS to find the shortest path between the two. The basic_block_link is to maintain parent links so that it can build a list of blocks from the start. slay. 💅
