749 %b print branch destination
750 %c print condition code (always bits 28-31)
751 %m print register mask for ldm/stm instruction
752 %o print operand2 (immediate or register + shift)

754 %t print 't' iff bit 21 set and bit 24 clear
755 %B print arm BLX(1) destination
756 %C print the PSR sub type.
757 %U print barrier type.
758 %P print address for pli instruction.
759
760 %<bitfield>r print as an ARM register
761 %<bitfield>d print the bitfield in decimal
762 %<bitfield>W print the bitfield plus one in decimal
763 %<bitfield>x print the bitfield in hex
764 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"
