/* The opcode table.
The format of the opcode table is:
- NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }. */
+ 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. */
