79 %u print condition code (unconditional in ARM mode)
80 %A print address for ldc/stc/ldf/stf instruction
81 %B print vstm/vldm register list
82 %I print cirrus signed shift immediate: bits 0..3|4..6
83 %F print the COUNT field of a LFM/SFM instruction.
84 %P print floating point precision in arithmetic insn
85 %Q print floating point precision in ldf/stf insn
86 %R print floating point rounding mode
88 %<bitfield>r print as an ARM register
89 %<bitfield>R as %<>r but r15 is UNPREDICTABLE
90 %<bitfield>ru as %<>r but each u register must be unique.
91 %<bitfield>d print the bitfield in decimal
92 %<bitfield>k print immediate for VFPv3 conversion instruction
93 %<bitfield>x print the bitfield in hex
94 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"
95 %<bitfield>f print a floating point constant if >7 else a
96 floating point register
97 %<bitfield>w print as an iWMMXt width field - [bhwd]ss/us
98 %<bitfield>g print as an iWMMXt 64-bit register
99 %<bitfield>G print as an iWMMXt general purpose or control register
100 %<bitfield>D print as a NEON D register
101 %<bitfield>Q print as a NEON Q register
103 %y<code> print a single precision VFP reg.

109 %<bitfield>`c print specified char iff bitfield is all zeroes
110 %<bitfield>?ab... select from array of values in big endian order
112 %L print as an iWMMXt N/M width field.
113 %Z print the Immediate of a WSHUFH instruction.
114 %l like 'A' except use byte offsets for 'B' & 'H'
116 %i print 5-bit immediate in bits 8,3..0

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.

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.

1307 %K print a 16-bit immediate from hw2[3:0],hw1[3:0],hw2[11:4]
1308 %S print a possibly-shifted Rm
1310 %a print the address of a plain load/store

1312 %m print register mask for ldm/stm
1314 %E print the lsb and width fields of a bfc/bfi instruction

1316 %b print a conditional 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.

1323 %x print warning if conditional an not at end of IT block"
1324 %X print "\t; unpredictable <IT:code>" if conditional
1326 %<bitfield>d print bitfield in decimal
1327 %<bitfield>W print bitfield*4 in decimal

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. */
