| 180 // Double Registers | |
| 181 // The rules of ADL require that double registers be defined in pairs. | |
| 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 | |
| 185 // CPU stores such a register pair to memory, the word associated with | |
| 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 | |
| 191 // with the macroassembler, using reg_to_DoubleFloatRegister_object(). | |
| 605 | 192 // 255 is a flag meaning "don't go here". |
| 0 | 193 // I believe we can't handle callee-save doubles D32 and up until |
| 194 // the place in the sparc stack crawler that asserts on the 255 is | |
| 195 // fixed up. | |

| 1907 //----------ENCODING BLOCK----------------------------------------------------- | |
| 1908 // This block specifies the encoding classes used by the compiler to output | |
| 1909 // byte streams. Encoding classes are parameterized macros used by | |
| 1910 // Machine Instruction Nodes in order to generate the bit encoding of the | |
| 1911 // instruction. Operands specify their base encoding interface with the | |
| 1912 // interface keyword. There are currently supported four interfaces, | |
| 1913 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
| 1914 // operand to generate a function which returns its register number when | |
| 1915 // queried. CONST_INTER causes an operand to generate a function which | |
| 1916 // returns the value of the constant when queried. MEMORY_INTER causes an | |
| 1917 // operand to generate four functions which return the Base Register, the | |
| 1918 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 1919 // queried. COND_INTER causes an operand to generate six functions which | |
| 1920 // return the encoding code (ie - encoding bits for the instruction) | |
| 1921 // associated with each basic boolean condition for a conditional instruction. | |
| 1922 // | |
| 1923 // Instructions specify two basic values for encoding. Again, a function | |
| 1924 // is available to check if the constant displacement is an oop. They use the | |
| 1925 // ins_encode keyword to specify their encoding classes (which must be | |
| 1926 // a sequence of enc_class names, and their parameters, specified in | |
| 1927 // the encoding block), and they use the | |
| 1928 // opcode keyword to specify, in order, their primary, secondary, and | |
| 1929 // tertiary opcode. Only the opcode sections which a particular instruction | |
| 1930 // needs for encoding need to be specified. | |

| 9016 // Currently we hold longs in 2 registers. Comparing such values efficiently | |
| 9017 // is tricky. The flavor of compare used depends on whether we are testing | |
| 9018 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
| 9019 // The GE test is the negated LT test. The LE test can be had by commuting | |
| 9020 // the operands (yielding a GE test) and then negating; negate again for the | |
| 9021 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
| 9022 // NE test is negated from that. | |
| 9023 | |
| 9024 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
| 9025 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
| 9026 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |
| 9027 // are collapsed internally in the ADLC's dfa-gen code. The match for | |
| 9028 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
| 9029 // foo match ends up with the wrong leaf. One fix is to not match both | |
| 9030 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |
