Content-Type: text/plain; charset="ISO-8859-1" Content-Transfer-Encoding: 7bit X-IsSubscribed: yes X-SW-Source: 2013-12/txt/msg00142.txt.bz2 This patch set is inspired by two previous patches I've posted: https://sourceware.org/ml/gdb-patches/2013-08/msg00305.html https://sourceware.org/ml/gdb-patches/2013-08/msg00309.html but I think can exist as a separate piece of work. The vector of unavailable parts of a value is currently byte based. Given that we can model a value down to the bit level, we can potentially loose information with the current implementation. After the patch we model the unavailable information in bits. Tested on x86-64 linux, including against native gdbserver. Thanks, Andrew
