| 182 // Each pair must be two 32-bit values, but not necessarily a pair of | |
| 183 // single float registers. In each pair, ADLC-assigned register numbers | |
| 184 // must be adjacent, with the lower number even. Finally, when the | |

| 186 // the lower ADLC-assigned number must be stored to the lower address. | |
| 187 | |
| 188 // These definitions specify the actual bit encodings of the sparc | |
| 189 // double fp register numbers. FloatRegisterImpl in register_sparc.hpp | |
| 190 // wants 0-63, so we have to convert every time we want to use fp regs | |

| 1913 // This block specifies the encoding classes used by the compiler to output | |
| 1914 // byte streams. Encoding classes are parameterized macros used by | |
| 1915 // Machine Instruction Nodes in order to generate the bit encoding of the | |
| 1916 // instruction. Operands specify their base encoding interface with the | |
| 1917 // interface keyword. There are currently supported four interfaces, | |
| 1918 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
| 1919 // operand to generate a function which returns its register number when | |
| 1920 // queried. CONST_INTER causes an operand to generate a function which | |
| 1921 // returns the value of the constant when queried. MEMORY_INTER causes an | |
| 1922 // operand to generate four functions which return the Base Register, the | |
| 1923 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 1924 // queried. COND_INTER causes an operand to generate six functions which | |
| 1925 // return the encoding code (ie - encoding bits for the instruction) | |
| 1926 // associated with each basic boolean condition for a conditional instruction. | |
| 1927 // | |
| 1928 // Instructions specify two basic values for encoding. Again, a function | |
| 1929 // is available to check if the constant displacement is an oop. They use the | |
| 1930 // ins_encode keyword to specify their encoding classes (which must be | |
| 1931 // a sequence of enc_class names, and their parameters, specified in | |
| 1932 // the encoding block), and they use the | |
| 1933 // opcode keyword to specify, in order, their primary, secondary, and | |
| 1934 // tertiary opcode. Only the opcode sections which a particular instruction | |

| 9086 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
| 9087 // The GE test is the negated LT test. The LE test can be had by commuting | |
| 9088 // the operands (yielding a GE test) and then negating; negate again for the | |
| 9089 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
| 9090 // NE test is negated from that. | |
| 9091 | |
| 9092 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
| 9093 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
| 9094 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |

| 9096 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
| 9097 // foo match ends up with the wrong leaf. One fix is to not match both | |
| 9098 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |

| 9746 // All peephole optimizations can be turned off using -XX:-OptoPeephole | |
| 9747 // | |
| 9748 // Each peephole rule is given an identifying number starting with zero and | |
| 9749 // increasing by one in the order seen by the parser. An individual peephole | |
| 9750 // can be enabled, and all others disabled, by using -XX:OptoPeepholeAt=# | |
| 9751 // on the command-line. | |
| 9752 // | |
| 9753 // ---------CURRENT LIMITATIONS---------------------------------------------- | |
| 9754 // | |
| 9755 // Only match adjacent instructions in same basic block | |
| 9756 // Only equality constraints | |
| 9757 // Only constraints between operands, not (0.dest_reg == EAX_enc) | |
| 9758 // Only one replacement instruction | |
| 9759 // | |
