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 invisible to the allocator (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)

1083 // for a volatile write
1084 //
1085 // dmb ish

1087 // dmb ish
1088 //
1089 // We can also use ldaxr and stlxr to implement compare and swap CAS

1091 // sequence like the following
1092 //
1093 // dmb ish
1094 // retry:

1101 // cset r0, eq
1102 // dmb ishld
1103 //
1104 // Note that the exclusive store is already using an stlxr
1105 // instruction. That is required to ensure visibility to other
1106 // threads of the exclusive write (assuming it succeeds) before that
1107 // of any subsequent writes.
1108 //
1109 // The following instruction sequence is an improvement on the above

1116 // cbnz rval retry

1120 // We don't need the leading dmb ish since the stlxr guarantees
1121 // visibility of prior writes in the case that the swap is
1122 // successful. Crucially we don't have to worry about the case where
1123 // the swap is not successful since no valid program should be
1124 // relying on visibility of prior changes by the attempting thread
1125 // in the case where the CAS fails.
1126 //
1127 // Similarly, we don't need the trailing dmb ishld if we substitute
1128 // an ldaxr instruction since that will provide all the guarantees we
1129 // require regarding observation of changes made by other threads
1130 // before any change to the CAS address observed by the load.
1131 //
1132 // In order to generate the desired instruction sequence we need to
1133 // be able to identify specific 'signature' ideal graph node
1134 // sequences which i) occur as a translation of a volatile reads or
1135 // writes or CAS operations and ii) do not occur through any other
1136 // translation or graph transformation. We can then provide
1137 // alternative aldc matching rules which translate these node
1138 // sequences to the desired machine code sequences. Selection of the
1139 // alternative rules can be implemented by predicates which identify
1140 // the relevant node sequences.
1141 //
1142 // The ideal graph generator translates a volatile read to the node

1144 //
1145 // LoadX[mo_acquire]

1150 //
1151 // LoadN[mo_acquire]
1152 // DecodeN
1153 // MemBarAcquire
1154 //
1155 // A volatile write is translated to the node sequence
1156 //
1157 // MemBarRelease
1158 // StoreX[mo_release] {CardMark}-optional
1159 // MemBarVolatile
1160 //
1161 // n.b. the above node patterns are generated with a strict
1162 // 'signature' configuration of input and output dependencies (see
1163 // the predicates below for exact details). The card mark may be as
1164 // simple as a few extra nodes or, in a few GC configurations, may
1165 // include more complex control flow between the leading and
1166 // trailing memory barriers. However, whatever the card mark
1167 // configuration these signatures are unique to translated volatile
1168 // reads/stores -- they will not appear as a result of any other
1169 // bytecode translation or inlining nor as a consequence of
1170 // optimizing transforms.
1171 //
1172 // We also want to catch inlined unsafe volatile gets and puts and
1173 // be able to implement them using either ldar<x>/stlr<x> or some
1174 // combination of ldr<x>/stlr<x> and dmb instructions.
1175 //
1176 // Inlined unsafe volatiles puts manifest as a minor variant of the
1177 // normal volatile put node sequence containing an extra cpuorder
1178 // membar
1179 //
1180 // MemBarRelease
1181 // MemBarCPUOrder
1182 // StoreX[mo_release] {CardMark}-optional
1183 // MemBarCPUOrder
1184 // MemBarVolatile
1185 //
1186 // n.b. as an aside, a cpuorder membar is not itself subject to
1187 // matching and translation by adlc rules. However, the rule
1188 // predicates need to detect its presence in order to correctly
1189 // select the desired adlc rules.
1190 //
1191 // Inlined unsafe volatile gets manifest as a slightly different
1192 // node sequence to a normal volatile get because of the
1193 // introduction of some CPUOrder memory barriers to bracket the
1194 // Load. However, but the same basic skeleton of a LoadX feeding a
1195 // MemBarAcquire, possibly thorugh an optional DecodeN, is still
1196 // present
1197 //
1198 // MemBarCPUOrder
1199 // || \\
1200 // MemBarCPUOrder LoadX[mo_acquire]
1201 // || |
1202 // || {DecodeN} optional
1203 // || /
1204 // MemBarAcquire
1205 //
1206 // In this case the acquire membar does not directly depend on the
1207 // load. However, we can be sure that the load is generated from an
1208 // inlined unsafe volatile get if we see it dependent on this unique
1209 // sequence of membar nodes. Similarly, given an acquire membar we
1210 // can know that it was added because of an inlined unsafe volatile
1211 // get if it is fed and feeds a cpuorder membar and if its feed
1212 // membar also feeds an acquiring load.
1213 //
1214 // Finally an inlined (Unsafe) CAS operation is translated to the
1215 // following ideal graph
1216 //
1217 // MemBarRelease
1218 // MemBarCPUOrder
1219 // CompareAndSwapX {CardMark}-optional
1220 // MemBarCPUOrder
1221 // MemBarAcquire
1222 //
1223 // So, where we can identify these volatile read and write
1224 // signatures we can choose to plant either of the above two code
1225 // sequences. For a volatile read we can simply plant a normal
1226 // ldr<x> and translate the MemBarAcquire to a dmb. However, we can
1227 // also choose to inhibit translation of the MemBarAcquire and
1228 // inhibit planting of the ldr<x>, instead planting an ldar<x>.
1229 //
1230 // When we recognise a volatile store signature we can choose to
1231 // plant at a dmb ish as a translation for the MemBarRelease, a
1232 // normal str<x> and then a dmb ish for the MemBarVolatile.
1233 // Alternatively, we can inhibit translation of the MemBarRelease
1234 // and MemBarVolatile and instead plant a simple stlr<x>
1235 // instruction.
1236 //
1237 // when we recognise a CAS signature we can choose to plant a dmb
1238 // ish as a translation for the MemBarRelease, the conventional
1239 // macro-instruction sequence for the CompareAndSwap node (which
1240 // uses ldxr<x>) and then a dmb ishld for the MemBarAcquire.
1241 // Alternatively, we can elide generation of the dmb instructions
1242 // and plant the alternative CompareAndSwap macro-instruction
1243 // sequence (which uses ldaxr<x>).
1244 //
1245 // Of course, the above only applies when we see these signature
1246 // configurations. We still want to plant dmb instructions in any
1247 // other cases where we may see a MemBarAcquire, MemBarRelease or
1248 // MemBarVolatile. For example, at the end of a constructor which
1249 // writes final/volatile fields we will see a MemBarRelease
1250 // instruction and this needs a 'dmb ish' lest we risk the
1251 // constructed object being visible without making the
1252 // final/volatile field writes visible.
1253 //
1254 // n.b. the translation rules below which rely on detection of the
1255 // volatile signatures and insert ldar<x> or stlr<x> are failsafe.
1256 // If we see anything other than the signature configurations we
1257 // always just translate the loads and stores to ldr<x> and str<x>

2465 //----------ENCODING BLOCK-----------------------------------------------------
2466 // This block specifies the encoding classes used by the compiler to
2467 // output byte streams. Encoding classes are parameterized macros
2468 // used by Machine Instruction Nodes in order to generate the bit
2469 // encoding of the instruction. Operands specify their base encoding
2470 // interface with the interface keyword. There are currently
2471 // supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, &
2472 // COND_INTER. REG_INTER causes an operand to generate a function
2473 // which returns its register number when queried. CONST_INTER causes
2474 // an operand to generate a function which returns the value of the
2475 // constant when queried. MEMORY_INTER causes an operand to generate
2476 // four functions which return the Base Register, the Index Register,
2477 // the Scale Value, and the Offset Value of the operand when queried.
2478 // COND_INTER causes an operand to generate six functions which return
2479 // the encoding code (ie - encoding bits for the instruction)
2480 // associated with each basic boolean condition for a conditional
2481 // instruction.
2482 //
2483 // Instructions specify two basic values for encoding. Again, a
2484 // function is available to check if the constant displacement is an
2485 // oop. They use the ins_encode keyword to specify their encoding
2486 // classes (which must be a sequence of enc_class names, and their
2487 // parameters, specified in the encoding block), and they use the
2488 // opcode keyword to specify, in order, their primary, secondary, and
2489 // tertiary opcode. Only the opcode sections which a particular
2490 // instruction needs for encoding need to be specified.
2491 encode %{
2492 // Build emit functions for each basic byte or larger field in the
2493 // intel encoding scheme (opcode, rm, sib, immediate), and call them
2494 // from C++ code in the enc_class source block. Emit functions will
2495 // live in the main source block for now. In future, we can
