93 * 'l' target long (32 or 64 bit)
94 * 'M' Non-negative target long (32 or 64 bit), in user mode the
95 * value is multiplied by 2^20 (think Mebibyte)
96 * 'o' octets (aka bytes)
97 * user mode accepts an optional E, e, P, p, T, t, G, g, M, m,
98 * K, k suffix, which multiplies the value by 2^60 for suffixes E
99 * and e, 2^50 for suffixes P and p, 2^40 for suffixes T and t,
100 * 2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k
101 * 'T' double
102 * user mode accepts an optional ms, us, ns suffix,
103 * which divides the value by 1e3, 1e6, 1e9, respectively
104 * '/' optional gdb-like print format (like "/10x")
105 *
106 * '?' optional type (for all types, except '/')
107 * '.' other form of optional type (for 'i' and 'l')
108 * 'b' boolean
