Question

尝试编译LLVM IR时，像这样

 llc main.ll -o main.s && g++ main.s -O3 -o main -pthread

我收到以下错误。同样的事情在我的Ubuntu 10系统上编译，但在CentOS中我得到以下错误。知道这里发生了什么，为什么LLVM会发疯？最后，如何解决这个问题？

Answer 1

看起来您的系统编译器错误编译了LLVM。有关已知损坏编译器的列表，请参阅http://llvm.org/docs/GettingStarted.html#brokengcc。

解决方案很简单 - 使用其他版本的编译器（在您的情况下为gcc）来编译LLVM。

Answer 2

这有一个类似的问题，这里漂浮在这里。答案是检查gcc和llvm的版本。原来一个是另外64位的32位。因人而异。

LLVM无法从IR编译
