Quick question: IIRC, earlier aarch64 gcc versions did not generate __ILP32__ when -mabi=ilp32, they only removed __LP64__. When did the change happen? Could we assume that all compiler versions used to generate ILP32 would define this? -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
