/* 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.

   %-escapes defined for these instructions:

       %%		%
       %<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"

       %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
       %A		print the address of a coprocessor 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 an unconditional branch offset
       %b		print a conditional branch offset
       %s		print the shift field of an SSAT instruction
       %R		print the rotation field of an SXT instruction

   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.  */
