The only place where I can se it doing this legally is for structure offsets. For example where a "load 4 byte word" instruction takes an offsetable address composed of a reg and an integer offset where the integer offset must be a multiple of 4.
This rule we do abide by in the kernel, because PARISC requires this.
Anything more is asking for trouble, I wouldn't want to use such a compiler in the real world :) - 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/
