/* Upper case letters in the instruction names here are macros.
'A' => print 'b' if no register operands or suffix_always is true
'B' => print 'b' if suffix_always is true
+ 'C' => print 's' or 'l' ('w' or 'd' in Intel mode) depending on operand
+ . size prefix
+ 'D' => print 'w' if no register operands or 'w', 'l' or 'q', if
+ . suffix_always is true
'E' => print 'e' if 32-bit form of jcxz
'F' => print 'w' or 'l' depending on address size prefix (loop insns)
+ 'G' => print 'w' or 'l' depending on operand size prefix (i/o 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'
+ 'O' => print 'd' or 'o' (or 'q' in Intel mode)
'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
. is true
- 'R' => print 'w', 'l' or 'q' ("wd" or "dq" in intel mode)
+ 'R' => print 'w', 'l' or 'q' ('d' for 'l' and 'e' 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', 'w' or 'l' ('d' in Intel mode)
'X' => print 's', 'd' depending on data16 prefix (for XMM)
- 'W' => print 'b' or 'w' ("w" or "de" in intel mode)
'Y' => 'q' if instruction has an REX 64bit overwrite prefix
+ 'Z' => print 'q' in 64bit mode and behave as 'L' otherwise
Many of the above letters print nothing in Intel mode. See "putop"
for the details.
