// |

|
40 |
// can be used without saving upon entry to the method, & |
|
41 |
// that they do not need to be saved at call sites. |
|
42 |
// |
|

// SOC = Save-On-Call: The register allocator assumes that these registers |
|
44 |
// can be used without saving upon entry to the method, |
|
45 |
// but that they must be saved at call sites. |

// method, but they do not need to be saved at call |
|
50 |
// sites. |

// register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get |

// spilled with LoadP/StoreP. If the register supports both, use Op_RegI. |

// output byte streams. Encoding classes are parameterized macros |
|
1677 |
// used by Machine Instruction Nodes in order to generate the bit |
|
1678 |
// encoding of the instruction. Operands specify their base encoding |
|
1679 |
// interface with the interface keyword. There are currently |
|
1680 |
// supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, & |
|
1681 |
// COND_INTER. REG_INTER causes an operand to generate a function |
|
1682 |
// which returns its register number when queried. CONST_INTER causes |
|
1683 |
// an operand to generate a function which returns the value of the |
|
1684 |
// constant when queried. MEMORY_INTER causes an operand to generate |
|
1685 |
// four functions which return the Base Register, the Index Register, |
|
1686 |
// the Scale Value, and the Offset Value of the operand when queried. |
|
1687 |
// COND_INTER causes an operand to generate six functions which return |
|
1688 |
// the encoding code (ie - encoding bits for the instruction) |

// associated with each basic boolean condition for a conditional |

|
1695 |
// classes (which must be a sequence of enc_class names, and their |
|
1696 |
// parameters, specified in the encoding block), and they use the |
|

// opcode keyword to specify, in order, their primary, secondary, and |

// Question: Why is r15_RegP (the read-only TLS register) a match for rRegP? |
3535 |
// Answer: Operand match rules govern the DFA as it processes instruction inputs. |
|
3536 |
// It's fine for an instruction input which expects rRegP to match a r15_RegP. |
|
3537 |
// The output of an instruction is controlled by the allocator, which respects |
|
3538 |
// register class masks, not match rules. Unless an instruction mentions |
|
3539 |
// r15_RegP or any_RegP explicitly as its output, r15 will not be considered |
|
3540 |
// by the allocator as an input. |
