   %<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>r		print as an ARM register
   %<bitfield>f		print a floating point constant if >7 else a
			floating point 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
   %c			print condition code (always bits 28-31)
   %P			print floating point precision in arithmetic insn
   %Q			print floating point precision in ldf/stf insn
   %R			print floating point rounding mode
   %<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
   %p			print 'p' iff bits 12-15 are 15
   %t			print 't' iff bit 21 set and bit 24 clear
   %o			print operand2 (immediate or register + shift)
   %a			print address for ldr/str instruction
   %s                   print address for ldr/str halfword/signextend instruction
   %b			print branch destination
   %B			print arm BLX(1) destination
   %A			print address for ldc/stc/ldf/stf instruction
   %m			print register mask for ldm/stm instruction
   %C			print the PSR sub type.
   %F			print the COUNT field of a LFM/SFM instruction.
Thumb specific format options:
   %D                   print Thumb register (bits 0..2 as high number if bit 7 set)
   %S                   print Thumb register (bits 3..5 as high number if bit 6 set)
   %<bitfield>I         print bitfield as a signed decimal
   				(top bit of range being the sign bit)
   %M                   print Thumb register mask
   %N                   print Thumb register mask (with LR)
   %O                   print Thumb register mask (with PC)
   %T                   print Thumb condition code (always bits 8-11)
   %I                   print cirrus signed shift immediate: bits 0..3|4..6
   %<bitfield>B         print Thumb branch destination (signed displacement)
   %<bitfield>W         print (bitfield * 4) as a decimal
   %<bitfield>H         print (bitfield * 2) as a decimal
   %<bitfield>a         print (bitfield * 4) as a pc-rel offset + decoded symbol
