| 1578 //----------ENCODING BLOCK----------------------------------------------------- | |
| 1579 // This block specifies the encoding classes used by the compiler to output | |
| 1580 // byte streams. Encoding classes generate functions which are called by | |
| 1581 // Machine Instruction Nodes in order to generate the bit encoding of the | |
| 1582 // instruction. Operands specify their base encoding interface with the | |
| 1583 // interface keyword. There are currently supported four interfaces, | |
| 1584 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
| 1585 // operand to generate a function which returns its register number when | |
| 1586 // queried. CONST_INTER causes an operand to generate a function which | |
| 1587 // returns the value of the constant when queried. MEMORY_INTER causes an | |
| 1588 // operand to generate four functions which return the Base Register, the | |
| 1589 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 1590 // queried. COND_INTER causes an operand to generate six functions which | |
| 1591 // return the encoding code (ie - encoding bits for the instruction) | |
| 1592 // associated with each basic boolean condition for a conditional instruction. | |
| 1593 // Instructions specify two basic values for encoding. They use the | |
| 1594 // ins_encode keyword to specify their encoding class (which must be one of | |
| 1595 // the class names specified in the encoding block), and they use the | |
| 1596 // opcode keyword to specify, in order, their primary, secondary, and | |
| 1597 // tertiary opcode. Only the opcode sections which a particular instruction | |
| 1598 // needs for encoding need to be specified. | |
| 1599 encode %{ | |
| 1600 // Build emit functions for each basic byte or larger field in the intel | |
| 1601 // encoding scheme (opcode, rm, sib, immediate), and call them from C++ | |
| 1602 // code in the enc_class source block. Emit functions will live in the | |
| 1603 // main source block for now. In future, we can generalize this by | |
| 1604 // adding a syntax that specifies the sizes of fields in an order, | |
| 1605 // so that the adlc can build the emit functions automagically | |

| 3256 // interpreter - such methods won't be compiled to use fast_lock and fast_unlock. | |
| 3257 // The interpreter provides two properties: | |
| 3258 // I1: At return-time the interpreter automatically and quietly unlocks any | |
| 3259 // objects acquired the current activation (frame). Recall that the | |
| 3260 // interpreter maintains an on-stack list of locks currently held by | |
| 3261 // a frame. | |
| 3262 // I2: If a method attempts to unlock an object that is not held by the | |
| 3263 // the frame the interpreter throws IMSX. | |
| 3264 // | |
| 3265 // Lets say A(), which has provably balanced locking, acquires O and then calls B(). | |
| 3266 // B() doesn't have provably balanced locking so it runs in the interpreter. | |
| 3267 // Control returns to A() and A() unlocks O. By I1 and I2, above, we know that O | |
| 3268 // is still locked by A(). | |
| 3269 // | |
| 3270 // The only other source of unbalanced locking would be JNI. The "Java Native Interface: | |
| 3271 // Programmer's Guide and Specification" claims that an object locked by jni_monitorenter | |
| 3272 // should not be unlocked by "normal" java-level locking and vice-versa. The specification | |

| 12341 // Long Compare | |
| 12342 // | |
| 12343 // Currently we hold longs in 2 registers. Comparing such values efficiently | |
| 12344 // is tricky. The flavor of compare used depends on whether we are testing | |
| 12345 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
| 12346 // The GE test is the negated LT test. The LE test can be had by commuting | |
| 12347 // the operands (yielding a GE test) and then negating; negate again for the | |
| 12348 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
| 12349 // NE test is negated from that. | |
| 12350 | |
| 12351 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
| 12352 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
| 12353 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |
| 12354 // are collapsed internally in the ADLC's dfa-gen code. The match for | |
| 12355 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
| 12356 // foo match ends up with the wrong leaf. One fix is to not match both | |
| 12357 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |
| 12358 // both forms beat the trinary form of long-compare and both are very useful | |
| 12359 // on Intel which has so few registers. | |
