/* The SystemV/386 SVR3.2 assembler, and probably all AT&T derived
   ix86 Unix assemblers, generate floating point instructions with
   reversed source and destination registers in certain cases.
   Unfortunately, gcc and possibly many other programs use this
   reversed syntax, so we're stuck with it.

   eg. `fsub %st(3),%st' results in st = st - st(3) as expected, but
   `fsub %st,%st(3)' results in st(3) = st - st(3), rather than
   the expected st(3) = st(3) - st

   This happens with all the non-commutative arithmetic floating point
   operations with two register operands, where the source register is
   %st, and destination register is %st(i).

   The affected opcode map is dceX, dcfX, deeX, defX.  */

   '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'
   'K' => print 'd' or 'q' if rex prefix is present.
   'L' => print 'l' if suffix_always is true
   '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.
   'Q' => print 'w', 'l' or 'q' if no register operands or suffix_always

   '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)
   '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.

   Braces '{' and '}', and vertical bars '|', indicate alternative
   mnemonic strings for AT&T, Intel, X86_64 AT&T, and X86_64 Intel
   modes.  In cases where there are only two alternatives, the X86_64
   instruction is reserved, and "(bad)" is printed.
