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

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.

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"
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
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.

1309 %S print a possibly-shifted Rm

1320 %R print the rotation field of an SXT instruction
1321 %U print barrier type.

1327 %<bitfield>d print bitfield in decimal

1338 to come dead last), this table was machine-sorted first in
1339 decreasing order of number of bits set in the mask, then in
1340 increasing numeric order of mask, then in increasing numeric order
1341 of opcode. This order is not the clearest for a human reader, but
1342 is guaranteed never to catch a special-case bit pattern with a more
1343 general mask, which is important, because this instruction encoding
1344 makes heavy use of special-case bit patterns. */
