66 %I print cirrus signed shift immediate: bits 0..3|4..6
67 %F print the COUNT field of a LFM/SFM instruction.
68 %P print floating point precision in arithmetic insn
69 %Q print floating point precision in ldf/stf insn
70 %R print floating point rounding mode
71
72 %<bitfield>r print as an ARM register
73 %<bitfield>d print the bitfield in decimal
74 %<bitfield>x print the bitfield in hex

86 %<bitnum>'c print specified char iff bit is one
87 %<bitnum>`c print specified char iff bit is zero
88 %<bitnum>?ab print a if bit is one else print b
89
90 %L print as an iWMMXt N/M width field.

409 %<bitfield>x print the bitfield in hex
410 %<bitfield>X print the bitfield as 1 hex digit without leading "0x"

412 %<bitnum>'c print specified char iff bit is one
413 %<bitnum>`c print specified char iff bit is zero
414 %<bitnum>?ab print a if bit is one else print b

844 of opcode. This order is not the clearest for a human reader, but
845 is guaranteed never to catch a special-case bit pattern with a more
846 general mask, which is important, because this instruction encoding
847 makes heavy use of special-case bit patterns. */
