* ================================================================
* SPL VM ABI (ir2vm 的正式约定；布局知识唯一来源)
* ================================================================
*
* 栈值槽 spl_val_t = sizeof(usize) = 8 字节。
* SIR 指令 type 只表达标量 tag（SPL_I8..SPL_PTR），聚合无 tag——
* 聚合值在 vreg 中是字节块，整体搬运用 NCALL vm_memcpy。
*
* ── 函数栈帧（字节坐标系，基址 = (char*)&stacks[fp]）─────────────
*
* [canary] fp-8 .. 0 （VM CALL 自动插入，ir2vm 不触碰）
* [params 区] fp+0 .. fp+Na （Na = C ABI 参数区字节数）
* [locals / vreg] fp+Na .. fp+Na+L
*
* ALLOC ceil((Na+L)/8) 一条 prologue；epilogue 走 RET。
* LADDR(imm) 的 imm 是字节偏移；canary 在 fp-1 槽，编译码不可见。
*
* ── 参数区 = C ABI（聚合值按值） ─────────────────────────────────
* 标量参数：align_up(off,8) 后占 8 字节（一槽）。
* 聚合参数：按聚合 size 排布跨多槽（align8 + size）。
* 调用方：标量 ld/PUSH 一槽；聚合逐 8 字节块压栈（聚合 vreg 强制 8 对齐）。
* 被调方：标量参数映射参数槽；聚合参数在 prologue memcpy 参数区 → param vreg，
* emit_value(param) 取 vreg 地址。参数槽数 = ceil(param_bytes/8) = CALL nargs。
*
* ── locals = 虚拟寄存器区 ────────────────────────────────────────
* 每个产生值的 IR 节点 = 一个 vreg（locals 区按类型对齐的字节块）。
* 纯值节点（type.const / mem.global_alloc / mem.alloca / 折叠 sizeof 等）不落 vreg，
* 引用处重算（PUSH / GADDR / LADDR）；其余产生值节点落 vreg，引用处 LOAD。
* 聚合 vreg 引用处返回其地址（LADDR），搬运经 vm_memcpy。
* mem.alloca(tid)(cnt) 的 vreg 槽即缓冲区本体，节点值 = LADDR(vreg_off)。
* 所有运算走 load/store：ld A; ld B; op; st Dst；立即数直接 PUSH。
*
* ── 调用 ──────────────────────────────────────────────────────────
* 调用方：逐参数压栈（标量一槽；聚合按 C ABI 逐 8 字节块）→ push fn_addr(或
* native_idx) → CALL n / NCALL n。返回值落 call 节点 vreg。
* 原生函数：IR 中 nodes 为空的函数（@extern 声明）→ 注册进 prog.natives，
* 加载时由 spl_syscall_register 填 impl；调用改 PUSH nat_idx + NCALL。
* 变参 nargs = 实际参数槽数。
*
* ── enum（不展开，直接保留）─────────────────────────────────────
* IR 层保留 enum 类型（不再展开为 struct）。enum 布局 = tag(usize, offset 0)
* + payload(offset 8，最大变体）。构造：agg.construct(enum)(tag, payload)；
* match：先取 tag 判定变体，再 extract(enum, 1) 一跳取 payload，
* field_tid = 变体具体类型（由 ast2ir 传入）。
*
* ── 返回 ──────────────────────────────────────────────────────────
* 标量：ld vreg(val); RET(tag)（RET 的 type 决定 VM 是否弹出返回值）。
* 聚合返回 = sret（自展开，不改 VM）：
* 被调函数签名尾部追加隐藏 *T 参数（最后一个）；返回时把聚合 vreg
* memcpy 到 sret 地址，RET(void)。
* 调用方在 locals 预留聚合槽（= call 节点 vreg），压其地址为最后实参；
* call 完成后聚合值已在该槽。
* 返回 void：RET(SPL_VOID)。
*
* ── 全局数据 ──────────────────────────────────────────────────────
* 任何聚合类型下（含 $root 顶层）的 var/const 属全局数据区。gdata 是
* spl_ir_node_vec_t，每条 = 一个 value 节点（type.const：标量折叠值，
* 聚合/无 init 零）。ir2vm 遍历求值 → SIR gdata 条目（字节 blob）。
* mem.global_alloc(tid, const_node) 的 const_node = gdata 向量索引，
* 降级为 GADDR(idx)。符号(def) → gdata 索引的解析在 ast2ir 收集期
* （gdata_ref 表），ir2vm 按索引直接用。
*
* ── 类型布局（C ABI，唯一实现处）────────────────────────────────
* type_align / type_size / field_offset：标量按 bits/8 对齐；
* struct 顺序对齐 + 尾填充；union 取最大字段；enum = tag(8) + 最大 payload；
* slice/range = [ptr, len] 各 8 字节；array = len * elem。
*
* ── 分支 ──────────────────────────────────────────────────────────
* control.br/jmp/select 的 label 是 IR node ref（基本块首指令）。两遍发射：
* 第一遍逐节点发指令并记录 label 节点 → 指令地址；第二遍回填
* JMP/BZ/BNZ 相对偏移 imm = target_addr - (jmp_addr + 1)。
