Please note that the data produced by "-g -fvar-tracking" is consumed by tools like systemtap, perf, crash, and makes a significant difference to the observability of debug AND non-debug kernels. (The presence of compiled-in DEBUG_* self-checking code is orthogonal to kernel observability via debuginfo.) Please consider only disabling var-tracking optionally/temporarily to work around this already-fixed compiler bug, but not losing high-quality dwarf data permanently. - FChE -- 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/
