/* The opcode table.
|
|
|
|
The format of the opcode table is:
|
|
|
|
NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.
|
|
|
|
The table is organised such that, where possible, all instructions with
|
|
the same mnemonic are together in a block. When the assembler searches
|
|
for a suitable instruction the entries are checked in table order, so
|
|
more specific, or specialised cases should appear earlier in the table.
|
|
|
|
As an example, consider two instructions 'add a,b,u6' and 'add
|
|
a,b,limm'. The first takes a 6-bit immediate that is encoded within the
|
|
32-bit instruction, while the second takes a 32-bit immediate that is
|
|
encoded in a follow-on 32-bit, making the total instruction length
|
|
64-bits. In this case the u6 variant must appear first in the table, as
|
|
all u6 immediates could also be encoded using the 'limm' extension,
|
|
however, we want to use the shorter instruction wherever possible.
|
|
|
|
It is possible though to split instructions with the same mnemonic into
|
|
multiple groups. However, the instructions are still checked in table
|
|
order, even across groups. The only time that instructions with the
|
|
same mnemonic should be split into different groups is when different
|
|
variants of the instruction appear in different architectures, in which
|
|
case, grouping all instructions from a particular architecture together
|
|
might be preferable to merging the instruction into the main instruction
|
|
table.
|
|
|
|
An example of this split instruction groups can be found with the 'sync'
|
|
instruction. The core arc architecture provides a 'sync' instruction,
|
|
while the nps instruction set extension provides 'sync.rd' and
|
|
'sync.wr'. The rd/wr flags are instruction flags, not part of the
|
|
mnemonic, so we end up with two groups for the sync instruction, the
|
|
first within the core arc instruction table, and the second within the
|
|
nps extension instructions. */
