Hi, in the UltraSPARC III user's manual, section 7.11 on page 175 describes
instruction formats. On page 176 the last two instructions are exactly the
same, i.e.
----------------------------------------
|op| fcn | op3 | --- |
----------------------------------------
----------------------------------------
|op| fcn | op3 | --- |
----------------------------------------
Is this a mistake or there is a reason for two identical diagrams for the same
instruction format??
Can you give a documentation part number and revision. In the documentation
I'm looking at the only encodings that match the above are:
----------------------------------------
|op | fcn | op3 | --- |
----------------------------------------
31 30 29 25 24 19 18 0
----------------------------------------
|op | rd | op3 | --- |
----------------------------------------
ie in the second there is an 'rd'.
I'm referring to some internal documentation for the particular
sparc v9 implementations of UltraSPARC-III and other processors;
it's based on the SPARC Arch Manual v9, and typically includes
all the fixed errata from that (You can download the errata from
sparc.org I think).
