%<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

%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
