ud ui5, also known as amswap.w rd,$r1,rj(rd==rj), is displayed as
"ud ui5" by default during disassembly. Alternatively, the original
instruction can be printed using the objdump -M no-aliases.
To implement this support, a format specifier "ru0:5,ru5:5" for ud is
applied exclusively during disassembly. This specifier indicates that
registers should be printed using their corresponding numeric values,
and when the instruction is identified as ud, only a single parameter
is displayed.
