One function, every tell
Time to read a function the way you'll read real game code: several optimizer fingerprints layered in one listing, none of them announced. First, a small worked example — damp(x, k), which clamps x up to zero, then multiplies by k:
0: bgez a0, 0xc # x already ≥ 0? skip the clamp
4: nop # …a PLAIN branch, slot unfilled
8: or a0, zero, zero # x = 0
c: multu a0, a1
10: mflo v0
14: nop # the two-slot window, unfilled
18: nop
1c: jr ra
20: nop
Inventory the tells: a sign-test branch (bgez — "branch if greater than or equal to zero") steering around a one-instruction clamp; a nop in its slot, because IDO doesn't always pick a likely form — read what's there, don't assume; then the multiply ritual with its fully-padded window. Three lessons' worth of fingerprints in nine lines, and the C is two short statements.
That's the skill this chapter was building: you no longer decode instruction by instruction. You spot shapes — there's a clamp, there's a multiply window — and assemble the C at the statement level.
The target stacks bigger shapes: a loop you'll recognize on sight from earlier in the chapter, feeding a multiply that closes the function. Name each section, then write the few lines of C that generate all of it.
