编译流水线 Pass 文档索引

前端到后端流水线

1. SimplExpr：CompCert C (Csyntax) → Clight
2. SimplLocals：Clight → Clight（局部变量提升/规整化）
3. Cshmgen：Clight → Csharpminor
4. Cminorgen：Csharpminor → Cminor
5. Selection：Cminor → CminorSel
6. RTLgen：CminorSel → RTL
7. Tailcall：RTL → RTL
8. Inlining：RTL → RTL
9. Renumber：RTL → RTL
10. Constprop：RTL → RTL
11. CSE：RTL → RTL
12. Deadcode：RTL → RTL
13. Unusedglob：RTL 程序级清理
14. Allocation：RTL → LTL（寄存器分配 + 校验）
15. Tunneling：LTL → LTL
16. Linearize：LTL → Linear
17. CleanupLabels：Linear → Linear
18. Debugvar：Linear → Linear（调试信息）
19. Stacking：Linear → Mach
20. Asmgen：Mach → Asm（架构相关）
21. Asmexpand：Asm → Asm（架构相关扩展）
