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

104 * 2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k
105 * 'T' double
106 * user mode accepts an optional ms, us, ns suffix,
107 * which divides the value by 1e3, 1e6, 1e9, respectively
108 * '/' optional gdb-like print format (like "/10x")
109 *
110 * '?' optional type (for all types, except '/')
111 * '.' other form of optional type (for 'i' and 'l')
