The args field is a string describing the operands. The following
letters can appear in the args:
c - a 5-bit control register index
d - a 5-bit destination register index
s - a 5-bit left source register index
t - a 5-bit right source register index
D - a 3-bit encoded destination register
S - a 3-bit encoded left source register
T - a 3-bit encoded right source register
i - a 16-bit signed immediate
j - a 5-bit unsigned immediate
k - a (second) 5-bit unsigned immediate
l - a 8-bit custom instruction constant
m - a 26-bit unsigned immediate
o - a 16-bit signed pc-relative offset
u - a 16-bit unsigned immediate
I - a 12-bit signed immediate
M - a 6-bit unsigned immediate
N - a 6-bit unsigned immediate with 2-bit shift
O - a 10-bit signed pc-relative offset with 1-bit shift
P - a 7-bit signed pc-relative offset with 1-bit shift
U - a 7-bit unsigned immediate with 2-bit shift
V - a 5-bit unsigned immediate with 2-bit shift
W - a 4-bit unsigned immediate with 2-bit shift
X - a 4-bit unsigned immediate with 1-bit shift
Y - a 4-bit unsigned immediate
e - an immediate coded as an enumeration for addi.n/subi.n
f - an immediate coded as an enumeration for slli.n/srli.n
g - an immediate coded as an enumeration for andi.n
h - an immediate coded as an enumeration for movi.n
R - a reglist for ldwm/stwm or push.n/pop.n
B - a base register specifier and option list for ldwm/stwm
Literal ',', '(', and ')' characters may also appear in the args as
delimiters.
Note that the args describe the semantics and assembly-language syntax
of the operands, not their encoding into the instruction word.
The pinfo field is INSN_MACRO for a macro. Otherwise, it is a collection
of bits describing the instruction, notably any relevant hazard
information.
When assembling, the match field contains the opcode template, which
is modified by the arguments to produce the actual opcode
that is emitted. If pinfo is INSN_MACRO, then this is 0.
If pinfo is INSN_MACRO, the mask field stores the macro identifier.
Otherwise this is a bit mask for the relevant portions of the opcode
when disassembling. If the actual opcode anded with the match field
equals the opcode field, then we have found the correct instruction. */
