This is fine for options used to > build the kernel itself, however some components like the x86 boot code > use a different set of flags. > > Add the new macro cc-option-raw which serves the same purpose as > cc-option but has additional parameters. One parameter is the compiler > with which the check should be performed, the other the compiler options > to be used instead KBUILD_C*FLAGS. The compiler parameter allows other > macros like hostcc-option to be implemented on top of cc-option-raw. > > Also rework cc-option to make use of cc-option-raw. > > Suggested-by: Arnd Bergmann <arnd@xxxxxxxx> > Suggested-by: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx> > Signed-off-by: Matthias Kaehlcke <mka@xxxxxxxxxxxx> > --- > Changes in v2: > - Changed macro name from Add cc-option-no-kbuild to cc-option-raw > - Added compiler as parameter to the macro > - Reworked cc-option to make use of cc-option-raw > - Updated commit message > > scripts/Kbuild.include | 9 +++++++-- > 1 file changed, 7 insertions(+), 2 deletions(-) > Acked-by: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx> (if nothing better pops up) -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
