Challenge yourself with complex addressing modes and strict stack lifecycle rules.

Knowledge Check
What does the addressing mode `[x29, w21, SXTW]` accomplish?
Knowledge Check
When variables are allocated dynamically within a block of code (like an if-statement) by decrementing the SP, how are they typically accessed?
Knowledge Check
If a memory allocation requires 32 bytes (including the frame record), what does the stack layout look like immediately after `stp x29, x30, [sp, -32]!` executes?
Knowledge Check
Why does the `ldp x29, x30, [sp], 16` instruction use a post-indexed addressing mode rather than pre-indexed?
Knowledge Check
If you need to scale a 64-bit register offset by 8 bytes before adding it to the base register, what syntax is required?
