Also, it's sort of feels wrong to have -mcpu in a place where we're exclusively doing -march. Perhaps the fallback should be bog standard -march=armv7-a? (or the fallback for that one "-march=armv5t -Wa$(comma)-march=armv7-a")? -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project -- 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/
