编译 kernel 时如何关闭警告？

Question

I'm trying to compile an android kernel using clang and I'm getting warnings that I don't care about. For compilation I use the command make -j3 CC=clang O=output , so I cannot just add the -Wno-everything argument as if I were using the command clang file.c . As I understand it, I can disable some warnings by adding #pragma to the file that causes the error. But also I have one strange error that does not reference any file:

warning: unknown warning option '-Wno-vectorizer-no-neon' [-Wunknown-warning-option]

How can I turn off all warnings? Or at least this one.

PS: Sorry for my English.

The solution was to add the -Wno-everything argument to the ARCH_CPPFLAGS parameter in the Makefile .
