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.

820 %<bitfield>R as %r but r15 is UNPREDICTABLE
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"
827
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
831
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.

1336 %H print a 16-bit immediate from hw2[3:0],hw1[11:0]
1337 %S print a possibly-shifted Rm
1338

1342 %m print register mask for ldm/stm

1344 %E print the lsb and width fields of a bfc/bfi instruction
1345 %F print the lsb and width fields of a sbfx/ubfx instruction
1346 %b print a conditional branch offset
1347 %B print an unconditional branch offset
1348 %s print the shift field of an SSAT instruction
1349 %R print the rotation field of an SXT instruction
1350 %U print barrier type.
1351 %P print address for pli instruction.
1352 %c print the condition code
1353 %x print warning if conditional an not at end of IT block"
1354 %X print "\t; unpredictable <IT:code>" if conditional
1355
1356 %<bitfield>d print bitfield in decimal
1357 %<bitfield>W print bitfield*4 in decimal
1358 %<bitfield>r print bitfield as an ARM register

1366 With one exception at the bottom (done because BL and BLX(1) need
1367 to come dead last), this table was machine-sorted first in
1368 decreasing order of number of bits set in the mask, then in
1369 increasing numeric order of mask, then in increasing numeric order
1370 of opcode. This order is not the clearest for a human reader, but
1371 is guaranteed never to catch a special-case bit pattern with a more
1372 general mask, which is important, because this instruction encoding
1373 makes heavy use of special-case bit patterns. */
