7431 | 1) only read/write when the register number is explicitly encoded in the | |

7433 | 2) only read CFM when accessing a rotating GR, FR, or PR. mov pr only | |
197865e8 | 7434 | accesses CFM when qualifying predicate is in the rotating region. |
800eeca4 JW |
7435 | 3) general register value is used to specify an indirect register; not |
7436 | determinable statically. | |
7437 | 4) only read the given resource when bits 7:0 of the indirect index | |
7438 | register value does not match the register number of the resource; not | |
7439 | determinable statically. | |
7440 | 5) all rules are implementation specific. | |
7441 | 6) only when both the index specified by the reader and the index specified | |
7442 | by the writer have the same value in bits 63:61; not determinable | |
197865e8 | 7443 | statically. |
800eeca4 | 7444 | 7) only access the specified resource when the corresponding mask bit is |
197865e8 | 7445 | set |
800eeca4 JW |
7446 | 8) PSR.dfh is only read when these insns reference FR32-127. PSR.dfl is |
7447 | only read when these insns reference FR2-31 | |
7448 | 9) PSR.mfl is only written when these insns write FR2-31. PSR.mfh is only | |
7449 | written when these insns write FR32-127 | |
7450 | 10) The PSR.bn bit is only accessed when one of GR16-31 is specified in the | |
7451 | instruction | |
7452 | 11) The target predicates are written independently of PR[qp], but source | |
7453 | registers are only read if PR[qp] is true. Since the state of PR[qp] | |
7454 | cannot statically be determined, all source registers are marked used. | |
7455 | 12) This insn only reads the specified predicate register when that | |
7456 | register is the PR[qp]. | |
7457 | 13) This reference to ld-c only applies to teh GR whose value is loaded | |
197865e8 | 7458 | with data returned from memory, not the post-incremented address register. |
800eeca4 JW |
7459 | 14) The RSE resource includes the implementation-specific RSE internal |
7460 | state resources. At least one (and possibly more) of these resources are | |
7461 | read by each instruction listed in IC:rse-readers. At least one (and | |
7462 | possibly more) of these resources are written by each insn listed in | |
197865e8 | 7463 | IC:rse-writers. |
800eeca4 | 7464 | 15+16) Represents reserved instructions, which the assembler does not |
197865e8 | 7465 | generate. |
800eeca4 JW |
7466 | |
7467 | Memory resources (i.e. locations in memory) are *not* marked or tracked by | |
7468 | this code; there are no dependency violations based on memory access. | |
