'C' => print 's' or 'l' ('w' or 'd' in Intel mode) depending on operand

|

'E' => print 'e' if 32-bit form of jcxz
|

'F' => print 'w' or 'l' depending on address size prefix (loop insns)
|

'H' => print ",pt" or ",pn" branch hint
|

'I' => honor following macro letter even in Intel mode (implemented only
|

. for some of the macro letters)
|

'J' => print 'l'
|
||
'L' => print 'l' if suffix_always is true
|

'N' => print 'n' if instruction has no wait "prefix"
|

'O' => print 'd', or 'o'
|

'P' => print 'w', 'l' or 'q' if instruction has an operand size prefix,

. or suffix_always is true. print 'q' if rex prefix is present.

'Q' => print 'w', 'l' or 'q' if no register operands or suffix_always

'R' => print 'w', 'l' or 'q' ("wd" or "dq" in intel mode)

'S' => print 'w', 'l' or 'q' if suffix_always is true
|
||
'T' => print 'q' in 64bit mode and behave as 'P' otherwise
|

'U' => print 'q' in 64bit mode and behave as 'Q' otherwise
|

'V' => print 'q' in 64bit mode and behave as 'S' otherwise
|

'W' => print 'b' or 'w' ("w" or "de" in intel mode)

'X' => print 's', 'd' depending on data16 prefix (for XMM)
|

'Y' => 'q' if instruction has an REX 64bit overwrite prefix

Many of the above letters print nothing in Intel mode. See "putop"
