Is it possible to make this in a way so all the instruction set use
|
| 39 |
flags can be read from the use.desc by some simple epression?
|
| 40 |
|
| 41 |
Like 1. "is" prefix/postfix for Instruction Set or 2. include the
|
| 42 |
"\sinstruction set\s" in the description? or 3. have them listed in
|
| 43 |
special file for that or 4. whatever we can agree on is the proper way.
|
