That prevents a lot of optimizations with out of line code. In fact even gcc with the right options can generate code that violates this. Standard Linux constructions, such as exception handling, also violate this. If your tool needs that your tool is broken. BTW any other frame pointer requirement should be also optional, as it slows down a number of CPUs, such as Atoms. -Andi -- 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/
