38 // Register Save Types:
39 //
40 // NS = No-Save: The register allocator assumes that these registers
41 // can be used without saving upon entry to the method, &
42 // that they do not need to be saved at call sites.
43 //
44 // SOC = Save-On-Call: The register allocator assumes that these registers
45 // can be used without saving upon entry to the method,
46 // but that they must be saved at call sites.
47 //
48 // SOE = Save-On-Entry: The register allocator assumes that these registers
49 // must be saved before using them upon entry to the
50 // method, but they do not need to be saved at call
51 // sites.
52 //
53 // AS = Always-Save: The register allocator assumes that these registers
54 // must be saved before using them upon entry to the
55 // method, & that they must be saved at call sites.
56 //
57 // Ideal Register Type is used to determine how to save & restore a
58 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get
59 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI.
60 //
61 // The encoding number is the actual bit-pattern placed into the opcodes.
62
63 // We must define the 64 bit int registers in two 32 bit halves, the
64 // real lower register and a virtual upper half register. upper halves
65 // are used by the register allocator but are not actually supplied as
66 // operands to memory ops.
67 //
68 // follow the C1 compiler in making registers
69 //
70 // r0-r7,r10-r26 volatile (caller save)
71 // r27-r32 system (no save, no allocate)
72 // r8-r9 non-allocatable (so we can use them as scratch regs)
73 //
74 // as regards Java usage. we don't use any callee save registers
75 // because this makes it difficult to de-optimise a frame (see comment
76 // in x86 implementation of Deoptimization::unwind_callee_save_values)

150 // Double Registers
151
152 // The rules of ADL require that double registers be defined in pairs.
153 // Each pair must be two 32-bit values, but not necessarily a pair of
154 // single float registers. In each pair, ADLC-assigned register numbers
155 // must be adjacent, with the lower number even. Finally, when the
156 // CPU stores such a register pair to memory, the word associated with
157 // the lower ADLC-assigned number must be stored to the lower address.
158
159 // AArch64 has 32 floating-point registers. Each can store a vector of
160 // single or double precision floating-point values up to 8 * 32
161 // floats, 4 * 64 bit floats or 2 * 128 bit floats. We currently only
162 // use the first float or double element of the vector.
163
164 // for Java use float registers v0-v15 are always save on call whereas
165 // the platform ABI treats v8-v15 as callee save). float registers
166 // v16-v31 are SOC as per the platform spec
167
168 // For SVE vector registers, we simply extend vector register size to 8
169 // 'logical' slots. This is nominally 256 bits but it actually covers
170 // all possible 'physical' SVE vector register lengths from 128 ~ 2048
171 // bits. The 'physical' SVE vector register length is detected during
172 // startup, so the register allocator is able to identify the correct
173 // number of bytes needed for an SVE spill/unspill.
174 // Note that a vector register with 4 slots denotes a 128-bit NEON
175 // register allowing it to be distinguished from the corresponding SVE
176 // vector register when the SVE vector length is 128 bits.

1382 // we simply need
1383 //
1384 // ldar<x>
1385 //
1386 // and for a volatile write we need
1387 //
1388 // stlr<x>
1389 //
1390 // Alternatively, we can implement them by pairing a normal
1391 // load/store with a memory barrier. For a volatile read we need
1392 //
1393 // ldr<x>
1394 // dmb ishld
1395 //
1396 // for a volatile write
1397 //
1398 // dmb ish
1399 // str<x>
1400 // dmb ish
1401 //
1402 // We can also use ldaxr and stlxr to implement compare and swap CAS
1403 // sequences. These are normally translated to an instruction
1404 // sequence like the following
1405 //
1406 // dmb ish
1407 // retry:
1408 // ldxr<x> rval raddr
1409 // cmp rval rold
1410 // b.ne done
1411 // stlxr<x> rval, rnew, rold
1412 // cbnz rval retry
1413 // done:
1414 // cset r0, eq
1415 // dmb ishld
1416 //
1417 // Note that the exclusive store is already using an stlxr
1418 // instruction. That is required to ensure visibility to other
1419 // threads of the exclusive write (assuming it succeeds) before that
1420 // of any subsequent writes.
1421 //
1422 // The following instruction sequence is an improvement on the above
1423 //
1424 // retry:
1425 // ldaxr<x> rval raddr
1426 // cmp rval rold
1427 // b.ne done
1428 // stlxr<x> rval, rnew, rold
1429 // cbnz rval retry
1430 // done:
1431 // cset r0, eq
1432 //
1433 // We don't need the leading dmb ish since the stlxr guarantees
1434 // visibility of prior writes in the case that the swap is
1435 // successful. Crucially we don't have to worry about the case where
1436 // the swap is not successful since no valid program should be
1437 // relying on visibility of prior changes by the attempting thread
1438 // in the case where the CAS fails.
1439 //
1440 // Similarly, we don't need the trailing dmb ishld if we substitute
1441 // an ldaxr instruction since that will provide all the guarantees we
1442 // require regarding observation of changes made by other threads
1443 // before any change to the CAS address observed by the load.
1444 //
1445 // In order to generate the desired instruction sequence we need to
1446 // be able to identify specific 'signature' ideal graph node
1447 // sequences which i) occur as a translation of a volatile reads or
1448 // writes or CAS operations and ii) do not occur through any other
1449 // translation or graph transformation. We can then provide
1450 // alternative aldc matching rules which translate these node
1451 // sequences to the desired machine code sequences. Selection of the
1452 // alternative rules can be implemented by predicates which identify
1453 // the relevant node sequences.
1454 //
1455 // The ideal graph generator translates a volatile read to the node
1456 // sequence
1457 //
1458 // LoadX[mo_acquire]
1459 // MemBarAcquire
1460 //
1461 // As a special case when using the compressed oops optimization we
1462 // may also see this variant
1463 //
1464 // LoadN[mo_acquire]
1465 // DecodeN
1466 // MemBarAcquire
1467 //
1468 // A volatile write is translated to the node sequence
1469 //
1470 // MemBarRelease
1471 // StoreX[mo_release] {CardMark}-optional
1472 // MemBarVolatile
1473 //
1474 // n.b. the above node patterns are generated with a strict
1475 // 'signature' configuration of input and output dependencies (see
1476 // the predicates below for exact details). The card mark may be as
1477 // simple as a few extra nodes or, in a few GC configurations, may
1478 // include more complex control flow between the leading and
1479 // trailing memory barriers. However, whatever the card mark
1480 // configuration these signatures are unique to translated volatile
1481 // reads/stores -- they will not appear as a result of any other
1482 // bytecode translation or inlining nor as a consequence of
1483 // optimizing transforms.
1484 //
1485 // We also want to catch inlined unsafe volatile gets and puts and
1486 // be able to implement them using either ldar<x>/stlr<x> or some
1487 // combination of ldr<x>/stlr<x> and dmb instructions.
1488 //
1489 // Inlined unsafe volatiles puts manifest as a minor variant of the
1490 // normal volatile put node sequence containing an extra cpuorder
1491 // membar
1492 //
1493 // MemBarRelease
1494 // MemBarCPUOrder
1495 // StoreX[mo_release] {CardMark}-optional
1496 // MemBarCPUOrder
1497 // MemBarVolatile
1498 //
1499 // n.b. as an aside, a cpuorder membar is not itself subject to
1500 // matching and translation by adlc rules. However, the rule
1501 // predicates need to detect its presence in order to correctly
1502 // select the desired adlc rules.
1503 //
1504 // Inlined unsafe volatile gets manifest as a slightly different
1505 // node sequence to a normal volatile get because of the
1506 // introduction of some CPUOrder memory barriers to bracket the
1507 // Load. However, but the same basic skeleton of a LoadX feeding a
1508 // MemBarAcquire, possibly thorugh an optional DecodeN, is still
1509 // present
1510 //
1511 // MemBarCPUOrder
1512 // || \\
1513 // MemBarCPUOrder LoadX[mo_acquire]
1514 // || |
1515 // || {DecodeN} optional
1516 // || /
1517 // MemBarAcquire
1518 //
1519 // In this case the acquire membar does not directly depend on the
1520 // load. However, we can be sure that the load is generated from an
1521 // inlined unsafe volatile get if we see it dependent on this unique
1522 // sequence of membar nodes. Similarly, given an acquire membar we
1523 // can know that it was added because of an inlined unsafe volatile
1524 // get if it is fed and feeds a cpuorder membar and if its feed
1525 // membar also feeds an acquiring load.
1526 //
1527 // Finally an inlined (Unsafe) CAS operation is translated to the
1528 // following ideal graph
1529 //
1530 // MemBarRelease
1531 // MemBarCPUOrder
1532 // CompareAndSwapX {CardMark}-optional
1533 // MemBarCPUOrder
1534 // MemBarAcquire
1535 //
1536 // So, where we can identify these volatile read and write
1537 // signatures we can choose to plant either of the above two code
1538 // sequences. For a volatile read we can simply plant a normal
1539 // ldr<x> and translate the MemBarAcquire to a dmb. However, we can
1540 // also choose to inhibit translation of the MemBarAcquire and
1541 // inhibit planting of the ldr<x>, instead planting an ldar<x>.
1542 //
1543 // When we recognise a volatile store signature we can choose to
1544 // plant at a dmb ish as a translation for the MemBarRelease, a
1545 // normal str<x> and then a dmb ish for the MemBarVolatile.
1546 // Alternatively, we can inhibit translation of the MemBarRelease
1547 // and MemBarVolatile and instead plant a simple stlr<x>
1548 // instruction.
1549 //
1550 // when we recognise a CAS signature we can choose to plant a dmb
1551 // ish as a translation for the MemBarRelease, the conventional
1552 // macro-instruction sequence for the CompareAndSwap node (which

2800 // output byte streams. Encoding classes are parameterized macros
2801 // used by Machine Instruction Nodes in order to generate the bit
2802 // encoding of the instruction. Operands specify their base encoding
2803 // interface with the interface keyword. There are currently
2804 // supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, &
2805 // COND_INTER. REG_INTER causes an operand to generate a function
2806 // which returns its register number when queried. CONST_INTER causes
2807 // an operand to generate a function which returns the value of the
2808 // constant when queried. MEMORY_INTER causes an operand to generate
2809 // four functions which return the Base Register, the Index Register,
2810 // the Scale Value, and the Offset Value of the operand when queried.
2811 // COND_INTER causes an operand to generate six functions which return
2812 // the encoding code (ie - encoding bits for the instruction)
2813 // associated with each basic boolean condition for a conditional
2814 // instruction.
2815 //
2816 // Instructions specify two basic values for encoding. Again, a
2817 // function is available to check if the constant displacement is an
2818 // oop. They use the ins_encode keyword to specify their encoding
2819 // classes (which must be a sequence of enc_class names, and their
2820 // parameters, specified in the encoding block), and they use the
2821 // opcode keyword to specify, in order, their primary, secondary, and
