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"
811
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
815
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.
818 %V print the 16-bit immediate field of a MOVT or MOVW instruction. */

1307 %K print a 16-bit immediate from hw2[3:0],hw1[3:0],hw2[11:4]
1308 %S print a possibly-shifted Rm
1309

1311 %w print the width and signedness of a core load/store

1315 %F print the lsb and width fields of a sbfx/ubfx instruction
1316 %b print a conditional branch offset
1317 %B print an unconditional branch offset
1318 %s print the shift field of an SSAT instruction
1319 %R print the rotation field of an SXT instruction
1320 %U print barrier type.
1321 %P print address for pli instruction.
1322 %c print the condition code
1323 %x print warning if conditional an not at end of IT block"
1324 %X print "\t; unpredictable <IT:code>" if conditional
1325
1326 %<bitfield>d print bitfield in decimal
1327 %<bitfield>W print bitfield*4 in decimal
1328 %<bitfield>r print bitfield as an ARM register

1336 With one exception at the bottom (done because BL and BLX(1) need
1337 to come dead last), this table was machine-sorted first in
1338 decreasing order of number of bits set in the mask, then in
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
1343 makes heavy use of special-case bit patterns. */
