# ============================================================

# Extern2Test - ExternalDecl/StateDecl 重定义错误最小化复现
|

#
|

# 在 TransPyV Test 的 deco_test.py 中,这三个声明在生成的 .ll 中
|
||||
# 被声明两次(line 56-60 和 62-66),导致 llc 报错:
|
||||
# llc.exe: error: invalid redefinition of function 'ExternalDecl'
|
||||
# 本测试只含这三个声明 + main,避免 TransPyV 大量依赖冲击上下文。

# 声明一个外部函数,翻译器应生成 declare 而非 define
