54 %% %
55 %<bitfield>d print the bitfield in decimal
56 %<bitfield>x print the bitfield in hex
57 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"
58 %<bitfield>W print the bitfield plus one in decimal
59 %<bitfield>r print as an ARM register
60 %<bitfield>f print a floating point constant if >7 else a
61 floating point register
62 %<code>y print a single precision VFP reg.
63 Codes: 0=>Sm, 1=>Sd, 2=>Sn, 3=>multi-list, 4=>Sm pair
64 %<code>z print a double precision VFP reg
65 Codes: 0=>Dm, 1=>Dd, 2=>Dn, 3=>multi-list
66 %c print condition code (always bits 28-31)
67 %P print floating point precision in arithmetic insn
68 %Q print floating point precision in ldf/stf insn
69 %R print floating point rounding mode
70 %<bitnum>'c print specified char iff bit is one
71 %<bitnum>`c print specified char iff bit is zero
72 %<bitnum>?ab print a if bit is one else print b
73 %p print 'p' iff bits 12-15 are 15
74 %t print 't' iff bit 21 set and bit 24 clear
75 %o print operand2 (immediate or register + shift)
76 %a print address for ldr/str instruction
77 %s print address for ldr/str halfword/signextend instruction

83 %F print the COUNT field of a LFM/SFM instruction.
84 %E print the LSB and WIDTH fields of a BFI or BFC instruction.
85 %V print the 16-bit immediate field of a MOVT or MOVW instruction.
86 IWMMXT specific format options:
87 %<bitfield>g print as an iWMMXt 64-bit register
88 %<bitfield>G print as an iWMMXt general purpose or control register
89 %<bitfield>w print as an iWMMXt width field - [bhwd]ss/us
90 %Z print the Immediate of a WSHUFH instruction.
91 %L print as an iWMMXt N/M width field.
92 %l like 'A' except use byte offsets for 'B' & 'H' versions
93 Thumb specific format options:
94 %D print Thumb register (bits 0..2 as high number if bit 7 set)
95 %S print Thumb register (bits 3..5 as high number if bit 6 set)
96 %<bitfield>I print bitfield as a signed decimal
97 (top bit of range being the sign bit)
98 %M print Thumb register mask
99 %N print Thumb register mask (with LR)
100 %O print Thumb register mask (with PC)
101 %T print Thumb condition code (always bits 8-11)
