807 %S like %s but allow UNPREDICTABLE addressing
808 %b print branch destination
809 %c print condition code (always bits 28-31)
810 %m print register mask for ldm/stm instruction
811 %o print operand2 (immediate or register + shift)
812 %p print 'p' iff bits 12-15 are 15
813 %t print 't' iff bit 21 set and bit 24 clear
814 %B print arm BLX(1) destination
815 %C print the PSR sub type.
816 %U print barrier type.
817 %P print address for pli instruction.

821 %<bitfield>{r|R}u as %{r|R} but if matches the other %u field then is UNPREDICTABLE
822 %<bitfield>{r|R}U as %{r|R} but if matches the other %U field then is UNPREDICTABLE
823 %<bitfield>d print the bitfield in decimal
824 %<bitfield>W print the bitfield plus one in decimal
825 %<bitfield>x print the bitfield in hex
826 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"
828 %<bitfield>'c print specified char iff bitfield is all ones
829 %<bitfield>`c print specified char iff bitfield is all zeroes
830 %<bitfield>?ab... select from array of values in big endian order
832 %e print arm SMI operand (bits 0..7,8..19).
833 %E print the LSB and WIDTH fields of a BFI or BFC instruction.
834 %V print the 16-bit immediate field of a MOVT or MOVW instruction.

1369 of opcode. This order is not the clearest for a human reader, but
1370 is guaranteed never to catch a special-case bit pattern with a more
1371 general mask, which is important, because this instruction encoding
