7749 | beginning of the mnemonic. | |
7750 | ||
7751 | This is not simply a hash table lookup, because of conditional | |
7752 | variants. Most instructions have conditional variants, which are | |
7753 | expressed with a _conditional affix_ to the mnemonic. If we were | |
7754 | to encode each conditional variant as a literal string in the opcode | |
7755 | table, it would have approximately 20,000 entries. | |
7756 | ||
7757 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
7758 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
7759 | instructions take the affix as an infix, notably the s-variants of | |
7760 | the arithmetic instructions. Of those instructions, all but six | |
7761 | have the infix appear after the third character of the mnemonic. | |
7762 | ||
7763 | Accordingly, the algorithm for looking up primary opcodes given | |
7764 | an identifier is: | |
7765 | ||
7766 | 1. Look up the identifier in the opcode table. | |
7767 | If we find a match, go to step U. | |
7768 | ||
7769 | 2. Look up the last two characters of the identifier in the | |
7770 | conditions table. If we find a match, look up the first N-2 | |
7771 | characters of the identifier in the opcode table. If we | |
7772 | find a match, go to step CE. | |
7773 | ||
7774 | 3. Look up the fourth and fifth characters of the identifier in | |
7775 | the conditions table. If we find a match, extract those | |
7776 | characters from the identifier, and look up the remaining | |
7777 | characters in the opcode table. If we find a match, go | |
7778 | to step CM. | |
7779 | ||
7780 | 4. Fail. | |
7781 | ||
7782 | U. Examine the tag field of the opcode structure, in case this is | |
7783 | one of the six instructions with its conditional infix in an | |
7784 | unusual place. If it is, the tag tells us where to find the | |
7785 | infix; look it up in the conditions table and set inst.cond | |
7786 | accordingly. Otherwise, this is an unconditional instruction. | |
7787 | Again set inst.cond accordingly. Return the opcode structure. | |
7788 | ||
7789 | CE. Examine the tag field to make sure this is an instruction that | |
7790 | should receive a conditional suffix. If it is not, fail. | |
7791 | Otherwise, set inst.cond from the suffix we already looked up, | |
7792 | and return the opcode structure. | |
7793 | ||
7794 | CM. Examine the tag field to make sure this is an instruction that | |
7795 | should receive a conditional infix after the third character. | |
7796 | If it is not, fail. Otherwise, undo the edits to the current | |
7797 | line of input and proceed as for case CE. */ | |
