升级 gcc 后如何修复编译器错误？

Question

我在 zlinux 机器上工作，我们将 gcc 从 v8.2.1 升级到 8.5.0。该代码在更新 gcc 之前有效。从那时起，我现在收到如下错误。这现在发生在多个文件上。它不可能是实际代码，因为它在升级之前都有效。这是由于 gcc 的升级而发生的变化。

这是生成的汇编代码中某些行末尾有垃圾字符的错误。

你可能想要 检查源代码以确保它可以工作（并在另一台机器上编译）或尝试另一个编译器。如果这些都不起作用，请尝试返回您使用的以前版本的 gcc。

这是一个语法问题，因此请使用新版本的 gcc 检查您的代码，看看是否有任何更改（可能没有）
