792 %S like %s but allow UNPREDICTABLE addressing
793 %b print branch destination
794 %c print condition code (always bits 28-31)
795 %m print register mask for ldm/stm instruction
796 %o print operand2 (immediate or register + shift)
797 %p print 'p' iff bits 12-15 are 15
798 %t print 't' iff bit 21 set and bit 24 clear
799 %B print arm BLX(1) destination
800 %C print the PSR sub type.
801 %U print barrier type.
802 %P print address for pli instruction.

804 %<bitfield>r print as an ARM register
805 %<bitfield>R as %r but r15 is UNPREDICTABLE
806 %<bitfield>{r|R}u as %{r|R} but if matches the other %u field then is UNPREDICTABLE
807 %<bitfield>{r|R}U as %{r|R} but if matches the other %U field then is UNPREDICTABLE
808 %<bitfield>d print the bitfield in decimal
809 %<bitfield>W print the bitfield plus one in decimal
810 %<bitfield>x print the bitfield in hex
811 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"
812
813 %<bitfield>'c print specified char iff bitfield is all ones
814 %<bitfield>`c print specified char iff bitfield is all zeroes
815 %<bitfield>?ab... select from array of values in big endian order
816
817 %e print arm SMI operand (bits 0..7,8..19).
818 %E print the LSB and WIDTH fields of a BFI or BFC instruction.
819 %V print the 16-bit immediate field of a MOVT or MOVW instruction. */

1319 %F print the lsb and width fields of a sbfx/ubfx instruction
1320 %b print a conditional branch offset
1321 %B print an unconditional branch offset
1322 %s print the shift field of an SSAT instruction
1323 %R print the rotation field of an SXT instruction
1324 %U print barrier type.
1325 %P print address for pli instruction.
1326 %c print the condition code
1327 %x print warning if conditional an not at end of IT block"
1328 %X print "\t; unpredictable <IT:code>" if conditional
1329
1330 %<bitfield>d print bitfield in decimal
1331 %<bitfield>W print bitfield*4 in decimal
1332 %<bitfield>r print bitfield as an ARM register

1340 With one exception at the bottom (done because BL and BLX(1) need
1341 to come dead last), this table was machine-sorted first in
1342 decreasing order of number of bits set in the mask, then in
1343 increasing numeric order of mask, then in increasing numeric order
1344 of opcode. This order is not the clearest for a human reader, but
1345 is guaranteed never to catch a special-case bit pattern with a more
1346 general mask, which is important, because this instruction encoding
1347 makes heavy use of special-case bit patterns. */
