   %A			print address for ldc/stc/ldf/stf instruction
   %I                   print cirrus signed shift immediate: bits 0..3|4..6
   %F			print the COUNT field of a LFM/SFM instruction.
   %P			print floating point precision in arithmetic insn
   %Q			print floating point precision in ldf/stf insn
   %R			print floating point rounding mode

   %<bitfield>r		print as an ARM register
   %<bitfield>d		print the bitfield in decimal
   %<bitfield>x		print the bitfield in hex
   %<bitfield>X		print the bitfield as 1 hex digit without leading "0x"
   %<bitfield>f		print a floating point constant if >7 else a
			floating point register
   %<bitfield>w         print as an iWMMXt width field - [bhwd]ss/us
   %<bitfield>g         print as an iWMMXt 64-bit register
   %<bitfield>G         print as an iWMMXt general purpose or control register

   %<code>y		print a single precision VFP reg.
			  Codes: 0=>Sm, 1=>Sd, 2=>Sn, 3=>multi-list, 4=>Sm pair
   %<code>z		print a double precision VFP reg
			  Codes: 0=>Dm, 1=>Dd, 2=>Dn, 3=>multi-list
   %<bitnum>'c		print specified char iff bit is one
   %<bitnum>`c		print specified char iff bit is zero
   %<bitnum>?ab		print a if bit is one else print b

   %L			print as an iWMMXt N/M width field.
   %Z			print the Immediate of a WSHUFH instruction.
   %l			like 'A' except use byte offsets for 'B' & 'H'
			versions.  */

   %b			print branch destination
   %c			print condition code (always bits 28-31)
   %m			print register mask for ldm/stm instruction
   %o			print operand2 (immediate or register + shift)
   %p			print 'p' iff bits 12-15 are 15
   %t			print 't' iff bit 21 set and bit 24 clear
   %B			print arm BLX(1) destination
   %C			print the PSR sub type.
   %U			print barrier type.
   %P			print address for pli instruction.

   %<bitfield>r		print as an ARM register
   %<bitfield>d		print the bitfield in decimal
   %<bitfield>W         print the bitfield plus one in decimal
   %<bitfield>x		print the bitfield in hex
   %<bitfield>X		print the bitfield as 1 hex digit without leading "0x"

   %<bitnum>'c		print specified char iff bit is one
   %<bitnum>`c		print specified char iff bit is zero
   %<bitnum>?ab		print a if bit is one else print b

   %e                   print arm SMI operand (bits 0..7,8..19).
   %E			print the LSB and WIDTH fields of a BFI or BFC instruction.
   %V                   print the 16-bit immediate field of a MOVT or MOVW instruction.  */

/* Thumb32 opcodes use the same table structure as the ARM opcodes.
   We adopt the convention that hw1 is the high 16 bits of .value and
   .mask, hw2 the low 16 bits.

   print_insn_thumb32 recognizes the following format control codes:

       %%		%

       %I		print a 12-bit immediate from hw1[10],hw2[14:12,7:0]
       %M		print a modified 12-bit immediate (same location)
       %J		print a 16-bit immediate from hw1[3:0,10],hw2[14:12,7:0]
       %K		print a 16-bit immediate from hw2[3:0],hw1[3:0],hw2[11:4]
       %S		print a possibly-shifted Rm

       %a		print the address of a plain load/store
       %w		print the width and signedness of a core load/store
       %m		print register mask for ldm/stm

       %E		print the lsb and width fields of a bfc/bfi instruction
       %F		print the lsb and width fields of a sbfx/ubfx instruction
       %b		print a conditional branch offset
       %B		print an unconditional branch offset
       %s		print the shift field of an SSAT instruction
       %R		print the rotation field of an SXT instruction
       %U		print barrier type.
       %P		print address for pli instruction.

       %<bitfield>d	print bitfield in decimal
       %<bitfield>W	print bitfield*4 in decimal
       %<bitfield>r	print bitfield as an ARM register
       %<bitfield>c	print bitfield as a condition code

       %<bitnum>'c	print "c" iff bit is one
       %<bitnum>`c	print "c" iff bit is zero
       %<bitnum>?ab	print "a" if bit is one, else "b"

   With one exception at the bottom (done because BL and BLX(1) need
   to come dead last), this table was machine-sorted first in
   decreasing order of number of bits set in the mask, then in
   increasing numeric order of mask, then in increasing numeric order
   of opcode.  This order is not the clearest for a human reader, but
   is guaranteed never to catch a special-case bit pattern with a more
   general mask, which is important, because this instruction encoding
   makes heavy use of special-case bit patterns.  */
