From: Andi Kleen on 10 Jun 2010 07:20 gcc 4.6 -Wall gained a new set but unused variable warning. First it was incredibly noisy, but when looking at it in detail it actually found some bugs. I haven't tried to fix all occurrences, but at least the major ones for my configuration. If someone is interested more work would be possible on this. There are still some warnings left, but no flood and there's really usually some code improvement. In a few cases I simply shut up the compiler, but in many other cases dead code is gone or a real problem has been fixed. Some of the changes need more review (especially marked and with suitable cc), but most are straight forward. I did not fix all bugs -- those that were too hard are just commented with the warning left in. I also marked areas that need more attention in the individual patches. Andrew, something for your tree? -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
