36 // Register Save Types: | |
37 // | |
38 // NS = No-Save: The register allocator assumes that these registers | |
39 // can be used without saving upon entry to the method, & | |
40 // that they do not need to be saved at call sites. | |
41 // | |
42 // SOC = Save-On-Call: The register allocator assumes that these registers | |
43 // can be used without saving upon entry to the method, | |
44 // but that they must be saved at call sites. | |
45 // | |
46 // SOE = Save-On-Entry: The register allocator assumes that these registers | |
47 // must be saved before using them upon entry to the | |
48 // method, but they do not need to be saved at call | |
49 // sites. | |

52 // must be saved before using them upon entry to the | |
53 // method, & that they must be saved at call sites. | |
54 // | |
55 // Ideal Register Type is used to determine how to save & restore a | |
56 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get | |
57 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI. | |

8648 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
8649 // The GE test is the negated LT test. The LE test can be had by commuting | |
8650 // the operands (yielding a GE test) and then negating; negate again for the | |
8651 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
8652 // NE test is negated from that. | |
8653 | |
8654 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
8655 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
8656 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |
8657 // are collapsed internally in the ADLC's dfa-gen code. The match for | |
8658 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
8659 // foo match ends up with the wrong leaf. One fix is to not match both | |
8660 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |
