错误：表达式需要 'double' 类型支持，但 ABI 'aapcs' 不支持

Question

我正在使用最新的 Clang (19) 编译 Android 内核，并且显示了该错误。

这是错误输出：

这是我正在使用的 Clang 工具链：https://github.com/XSans0/WeebX-Clang/releases/latest

这是内核源代码：https://github.com/LineageOS/android_kernel_xiaomi_vayu

也许我应该降级我的 Clang 编译器？或者有人知道怎么解决吗

我尝试启用 LLVM_IAS 但结果相同:(

在此提交中修复：https://github.com/llvm/llvm-project/commit/ea9ec80b7aa1bd34edd5b544cd41450573f2cbff

也许我应该使用稳定的 Clang 🤔
