In the args field, the following characters are unused:
- ' " & - / 34 6789:;< > @'
+ ' " - / 34 6789:;< > @'
' C M [\] '
- ' e g l y } '
+ ' e g } '
Here are all the characters:
i 11 bit immediate value at 31
j 14 bit immediate value at 31
k 21 bit immediate value at 31
+ l 16 bit immediate value at 31 (wide mode only, unusual encoding).
n nullification for branch instructions
N nullification for spop and copr instructions
w 12 bit branch displacement
# 14bit offset for double precision FP load long/store.
J Yet another 14bit offset with an unusual encoding.
K Yet another 14bit offset with an unusual encoding.
+ y 16bit offset for single precision FP long load/store (PA2.0 wide).
+ & 16bit offset for double precision FP long load/store (PA2.0 wide).
Y %sr0,%r31 -- implicit target of be,l instruction.
@ implicit immediate value of 0
fB operand 2 register with L/R halves at 15
fC operand 3 register with L/R halves at 16:18,21:23
fe Like fT, but encoding is different.
+ fE Same as fe, except prints a space before register during disasm.
+ fx target register at 15 (only for PA 2.0 long format FLDD/FSTD).
Float registers for fmpyadd and fmpysub:
