Maybe, it would mean that subsequent addresses may not be a multiple of rowsize though, which is useful. > > which are replaced with '** Skipped %u bytes of value 0x%x **' > > Using a custom message instead of just "*", like "hexdump" uses, will require > preprocessing the output when recovering the original binary data by > feeding it to e.g. "xxd". > This may sound worse than it is, though, as I never got "xxd" to work without > preprocessing anyway ;-) I think showing the details of the skipped values is useful when reading the output directly. In situations where binary extracts are desired, the feature can always be disabled. -- Alastair D'Silva mob: 0423 762 819 skype: alastair_dsilva msn: alast...@d-silva.org blog: http://alastair.d-silva.org Twitter: @EvilDeece _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
