74 * TODO lift the restriction
75 * 'i' 32 bit integer
76 * 'l' target long (32 or 64 bit)
77 * 'M' just like 'l', except in user mode the value is
78 * multiplied by 2^20 (think Mebibyte)
79 * 'f' double
80 * user mode accepts an optional G, g, M, m, K, k suffix,
81 * which multiplies the value by 2^30 for suffixes G and
82 * g, 2^20 for M and m, 2^10 for K and k
83 * 'T' double
84 * user mode accepts an optional ms, us, ns suffix,
85 * which divides the value by 1e3, 1e6, 1e9, respectively
86 * '/' optional gdb-like print format (like "/10x")
87 *
88 * '?' optional type (for all types, except '/')
89 * '.' other form of optional type (for 'i' and 'l')
90 * 'b' boolean
91 * user mode accepts "on" or "off"
92 * '-' optional parameter (eg. '-f')
