'M' => print 'r' if intel_mnemonic is false.
'N' => print 'n' if instruction has no wait "prefix"
'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.
+ 'P' => behave as 'T' except with register operand outside of suffix_always
+ mode
'Q' => print 'w', 'l' or 'q' for memory operand or suffix_always
is true
'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 if instruction has no operand size
- prefix and behave as 'P' otherwise
- 'U' => print 'q' in 64bit mode if instruction has no operand size
- prefix and behave as 'Q' otherwise
- 'V' => print 'q' in 64bit mode if instruction has no operand size
- prefix and behave as 'S' otherwise
+ 'T' => print 'w', 'l'/'d', or 'q' if instruction has an operand size
+ prefix or if suffix_always is true.
+ 'U' unused.
+ 'V' unused.
'W' => print 'b', 'w' or 'l' ('d' in Intel mode)
'X' => print 's', 'd' depending on data16 prefix (for XMM)
'Y' unused.
'%' => add 1 upper case letter to the macro.
'^' => print 'w', 'l', or 'q' (Intel64 ISA only) depending on operand size
prefix or suffix_always is true (lcall/ljmp).
- '@' => print 'q' for Intel64 ISA, 'w' or 'q' for AMD64 ISA depending
- on operand size prefix.
- '&' => print 'q' in 64bit mode for Intel64 ISA or if instruction
- has no operand size prefix for AMD64 ISA, behave as 'P'
- otherwise
+ '@' => in 64bit mode for Intel64 ISA or if instruction
+ has no operand sizing prefix, print 'q' if suffix_always is true or
+ nothing otherwise; behave as 'P' in all other cases
2 upper case letter macros:
"XY" => print 'x' or 'y' if suffix_always is true or no register
