🌸 NAME 🌸

JUMP_TABLE_ENTRY — Create a jump table entry

✨ SYNOPSIS ✨

JUMP_TABLE_ENTRY (key , label );

---

🎀 ARGUMENTS 🎀

• key — Jump key identifier (typically a symbol address)
• label — Target label address

💅 DESCRIPTION 💅

This macro creates a jump table entry in the dedicated kernel section (__jump_table). Each entry contains the following information:

• Offset from current instruction to jump instruction (1b - .)
• Offset from current instruction to target label (label - .)
• Offset from current instruction to key identifier (key - .)

that's the whole breakdown, and yes, every one of those offsets is doing main character work ✨
