| 1897 // interface keyword. There are currently supported four interfaces, | |
| 1898 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
| 1899 // operand to generate a function which returns its register number when | |
| 1900 // queried. CONST_INTER causes an operand to generate a function which | |
| 1901 // returns the value of the constant when queried. MEMORY_INTER causes an | |
| 1902 // operand to generate four functions which return the Base Register, the | |
| 1903 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 1904 // queried. COND_INTER causes an operand to generate six functions which | |
| 1905 // return the encoding code (ie - encoding bits for the instruction) | |
| 1906 // associated with each basic boolean condition for a conditional instruction. | |
| 1907 // | |

| 8562 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
| 8563 // The GE test is the negated LT test. The LE test can be had by commuting | |

| 8565 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
| 8566 // NE test is negated from that. | |
| 8567 | |
| 8568 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
| 8569 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
| 8570 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |

| 8572 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
| 8573 // foo match ends up with the wrong leaf. One fix is to not match both | |
| 8574 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |

| 9018 //----------PEEPHOLE RULES----------------------------------------------------- | |
| 9019 // These must follow all instruction definitions as they use the names | |
| 9020 // defined in the instructions definitions. | |
| 9021 // | |
| 9022 // peepmatch ( root_instr_name [preceeding_instruction]* ); | |
| 9023 // | |
| 9024 // peepconstraint %{ | |
| 9025 // (instruction_number.operand_name relational_op instruction_number.operand_name | |
| 9026 // [, ...] ); | |
| 9027 // // instruction numbers are zero-based using left to right order in peepmatch | |
| 9028 // | |
| 9029 // peepreplace ( instr_name ( [instruction_number.operand_name]* ) ); | |
| 9030 // // provide an instruction_number.operand_name for each operand that appears | |
| 9031 // // in the replacement instruction's match rule | |
| 9032 // | |
| 9033 // ---------VM FLAGS--------------------------------------------------------- | |
| 9034 // | |
| 9035 // All peephole optimizations can be turned off using -XX:-OptoPeephole | |
| 9036 // | |
| 9037 // Each peephole rule is given an identifying number starting with zero and | |
| 9038 // increasing by one in the order seen by the parser. An individual peephole | |
| 9039 // can be enabled, and all others disabled, by using -XX:OptoPeepholeAt=# | |
| 9040 // on the command-line. | |
| 9041 // | |
| 9042 // ---------CURRENT LIMITATIONS---------------------------------------------- | |
| 9043 // | |
| 9044 // Only match adjacent instructions in same basic block | |
| 9045 // Only equality constraints | |
| 9046 // Only constraints between operands, not (0.dest_reg == EAX_enc) | |
| 9047 // Only one replacement instruction | |
| 9048 // | |
