Right. x86 will need this type of logic for 32-bit execs when they aren't not built on a 64-bit system, and for 64-bit execs when they aren't built on a 32-bit system. > > Something like... > > @for ARTIFACT in $(TEST_PROGS) $(TEST_PROGS_EXTENDED) $(TEST_FILES); do \ > if [ -f $$ARTIFACT ]; then \ > install -t $(INSTALL_PATH) $$ARTIFACT; \ > fi; \ > done; > I think it makes perfect sense to do this in INSTALL_RULE. As you said, this will avoid changes to test individual Makefiles and new test writers don't have to worry about adding this. Would you like make the necessary changes? thanks, -- Shuah -- Shuah Khan Sr. Linux Kernel Developer Open Source Innovation Group Samsung Research America (Silicon Valley) shuahkh@osg.samsung.com | (970) 217-8978 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
