790 %s print address for ldr/str halfword/signextend instruction
791 %S like %s but allow UNPREDICTABLE addressing
792 %b print branch destination
793 %c print condition code (always bits 28-31)
794 %m print register mask for ldm/stm instruction
795 %o print operand2 (immediate or register + shift)
796 %p print 'p' iff bits 12-15 are 15
797 %t print 't' iff bit 21 set and bit 24 clear
798 %B print arm BLX(1) destination
799 %C print the PSR sub type.
800 %U print barrier type.
801 %P print address for pli instruction.
803 %<bitfield>r print as an ARM register
804 %<bitfield>R as %r but r15 is UNPREDICTABLE
805 %<bitfield>{r|R}u as %{r|R} but if matches the other %u field then is UNPREDICTABLE
806 %<bitfield>{r|R}U as %{r|R} but if matches the other %U field then is UNPREDICTABLE
807 %<bitfield>d print the bitfield in decimal
808 %<bitfield>W print the bitfield plus one in decimal
809 %<bitfield>x print the bitfield in hex
810 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"
812 %<bitfield>'c print specified char iff bitfield is all ones
813 %<bitfield>`c print specified char iff bitfield is all zeroes
814 %<bitfield>?ab... select from array of values in big endian order
816 %e print arm SMI operand (bits 0..7,8..19).
817 %E print the LSB and WIDTH fields of a BFI or BFC instruction.

1339 increasing numeric order of mask, then in increasing numeric order
1340 of opcode. This order is not the clearest for a human reader, but
1341 is guaranteed never to catch a special-case bit pattern with a more
1342 general mask, which is important, because this instruction encoding
