98 * 'l' target long (32 or 64 bit)
99 * 'M' Non-negative target long (32 or 64 bit), in user mode the
100 * value is multiplied by 2^20 (think Mebibyte)

106 * 'T' double
107 * user mode accepts an optional ms, us, ns suffix,
108 * which divides the value by 1e3, 1e6, 1e9, respectively
109 * '/' optional gdb-like print format (like "/10x")
110 *
111 * '?' optional type (for all types, except '/')
112 * '.' other form of optional type (for 'i' and 'l')
