/* Basic 80960 instruction formats.
|
||
|
|
*
|
||
|
|
* The 'COJ' instructions are actually COBR instructions with the 'b' in
|
||
|
|
* the mnemonic replaced by a 'j'; they are ALWAYS "de-optimized" if necessary:
|
||
|
|
* if the displacement will not fit in 13 bits, the assembler will replace them
|
||
|
|
* with the corresponding compare and branch instructions.
|
||
|
|
*
|
||
|
|
* All of the 'MEMn' instructions are the same format; the 'n' in the name
|
||
|
|
* indicates the default index scale factor (the size of the datum operated on).
|
||
|
|
*
|
||
|
|
* The FBRA formats are not actually an instruction format. They are the
|
||
|
|
* "convenience directives" for branching on floating-point comparisons,
|
||
|
|
* each of which generates 2 instructions (a 'bno' and one other branch).
|
||
|
|
*
|
||
|
|
* The CALLJ format is not actually an instruction format. It indicates that
|
||
|
|
* the instruction generated (a CTRL-format 'call') should have its relocation
|
||
|
|
* specially flagged for link-time replacement with a 'bal' or 'calls' if
|
||
|
|
* appropriate.
