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. | |

1994 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
1995 // operand to generate a function which returns its register number when | |
1996 // queried. CONST_INTER causes an operand to generate a function which | |
1997 // returns the value of the constant when queried. MEMORY_INTER causes an | |
1998 // operand to generate four functions which return the Base Register, the | |
1999 // Index Register, the Scale Value, and the Offset Value of the operand when | |
2000 // queried. COND_INTER causes an operand to generate six functions which | |
2001 // return the encoding code (ie - encoding bits for the instruction) | |
2002 // associated with each basic boolean condition for a conditional instruction. | |

9208 // Long Compare | |

9212 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
9213 // The GE test is the negated LT test. The LE test can be had by commuting | |
9214 // the operands (yielding a GE test) and then negating; negate again for the | |
9215 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
9216 // NE test is negated from that. | |
9217 | |
9218 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
9219 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
9220 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |
9221 // are collapsed internally in the ADLC's dfa-gen code. The match for | |
9222 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
9223 // foo match ends up with the wrong leaf. One fix is to not match both | |
9224 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |
