 * 'l'          target long (32 or 64 bit)
83 84
 * 'M'          just like 'l', except in user mode the value is

90 91 92
 * 'T'          double
 *              user mode accepts an optional ms, us, ns suffix,
 *              which divides the value by 1e3, 1e6, 1e9, respectively
93 94
 * '/'          optional gdb-like print format (like "/10x")
 *
95 96
