// ======================
// ===== 思路 =====
// 【试验性提交】单变量：微块内层循环的 **预取语义**。
// 现状：[1] 在 `micro24` 的入口与内层循环头部各有一条 `prefetchnta 384(%[b])`
// （384 B = 恰好一次循环迭代的 b 前进量 `add $384, %[b]`）。
// ★ 本发唯一改动：`prefetchnta` → `prefetcht0`（两条同改），其余一字不动。
// 机理（为什么预期为正）：mikro 是**每个 4 行 i-block 被调一次、j 面板复用**——
// 同一条 B 微块行会在**后续 i-block 里再次被读**。`prefetchnta` 的语义是"该行即将失效、
// 尽早驱逐"（non-temporal），也就是把**马上要发生的复用**提前扔掉；
// `prefetcht0` 保留正常 LRU 语义 ⇒ 复用时命中 L1/L2。
// 【定价】判题机 in-situ：本刀的局部读数在**加载很重的本机**上为 −3.3%（`a64` 臂 −1.0%），
// 但按 `§2.18.906`（内存/落位类轴的本地读数**不能定符号**），**符号与幅度以本发判题机读数为准**。
// 正确性：只改预取 hint，不触碰任何数据路径；`mx_chk` n=256/512/1024 三查全 0、
// FNV 与 #105545 逐位相同（`5996794521752134075`），`tools/gcc93check.py` COMPILE OK。
