gdb: Add new 'print nibbles' feature
Make an introduction of a new print setting that can be set by 'set print nibbles [on|off]'. The default value if OFF, which can be changed by user manually. Of course, 'show print nibbles' is also included in the patch. The new feature displays binary values by group, with four bits per group. The motivation for this work is to enhance the readability of binary values. Here's a GDB session before this patch is applied. (gdb) print var_a $1 = 1230 (gdb) print/t var_a $2 = 10011001110 With this patch applied, we can use the new print setting to display the new form of the binary values. (gdb) print var_a $1 = 1230 (gdb) print/t var_a $2 = 10011001110 (gdb) set print nibbles on (gdb) print/t var_a $3 = 0100 1100 1110 Tested on x86_64 openSUSE Tumbleweed.
