Hi,recently when gentoo switches from gcc to clang for compiling chromium,
It starting to show some warning all over the place with the following text:

warning: unknown warning option '-Wno-enum-compare-switch'; did you mean '-Wno-enum-compare'? [-Wunknown-warning-option]
warning: unknown warning option '-Wno-null-pointer-arithmetic'; did you mean '-Wno-null-arithmetic'? [-Wunknown-warning-option]
2 warnings generated.


So it seems gcc have some parameters that are not supported by clang.

My concern is I am not sure if this parameters are important for security measurements. "no null arithmetic" seems important.

If this is only for stop showing warnings then this issue can be closed if you want.



PS: my cflags are: CFLAGS="-march=native -O2 -pipe"


Thank you for your work.
