37 // Register aliases for parts of the system:
39 // 64 bit values can be kept in g1-g5, o1-o5 and o7 and all 64 bits are safe
40 // across context switches in V8+ ABI. Of course, there are no 64 bit regs
41 // in V8 ABI. All 64 bits are preserved in V9 ABI for all registers.
43 // g2-g4 are scratch registers called "application globals". Their
44 // meaning is reserved to the "compilation system"--which means us!
45 // They are are not supposed to be touched by ordinary C code, although
46 // highly-optimized C code might steal them for temps. They are safe
47 // across thread switches, and the ABI requires that they be safe
48 // across function calls.
49 //
50 // g1 and g3 are touched by more modules. V8 allows g1 to be clobbered
51 // across func calls, and V8+ also allows g5 to be clobbered across
52 // func calls. Also, g1 and g5 can get touched while doing shared
53 // library loading.
54 //
55 // We must not touch g7 (it is the thread-self register) and g6 is
56 // reserved for certain tools. g0, of course, is always zero.

60 // %%%% The interpreter should be revisited to reduce global scratch regs.
62 // This global always holds the current JavaThread pointer:
64 REGISTER_DECLARATION(Register, G2_thread , G2);
65 REGISTER_DECLARATION(Register, G6_heapbase , G6);
67 // The following globals are part of the Java calling convention:
69 REGISTER_DECLARATION(Register, G5_method , G5);
70 REGISTER_DECLARATION(Register, G5_megamorphic_method , G5_method);
71 REGISTER_DECLARATION(Register, G5_inline_cache_reg , G5_method);
73 // The following globals are used for the new C1 & interpreter calling convention:
74 REGISTER_DECLARATION(Register, Gargs , G4); // pointing to the last argument
76 // This local is used to preserve G2_thread in the interpreter and in stubs:
77 REGISTER_DECLARATION(Register, L7_thread_cache , L7);
79 // These globals are used as scratch registers in the interpreter:
81 REGISTER_DECLARATION(Register, Gframe_size , G1); // SAME REG as G1_scratch
82 REGISTER_DECLARATION(Register, G1_scratch , G1); // also SAME
83 REGISTER_DECLARATION(Register, G3_scratch , G3);
84 REGISTER_DECLARATION(Register, G4_scratch , G4);
86 // These globals are used as short-lived scratch registers in the compiler:
88 REGISTER_DECLARATION(Register, Gtemp , G5);
90 // JSR 292 fixed register usages:
91 REGISTER_DECLARATION(Register, G5_method_type , G5);
92 REGISTER_DECLARATION(Register, G3_method_handle , G3);
93 REGISTER_DECLARATION(Register, L7_mh_SP_save , L7);
95 // The compiler requires that G5_megamorphic_method is G5_inline_cache_klass,
96 // because a single patchable "set" instruction (NativeMovConstReg,
97 // or NativeMovConstPatching for compiler1) instruction
98 // serves to set up either quantity, depending on whether the compiled
99 // call site is an inline cache or is megamorphic. See the function
100 // CompiledIC::set_to_megamorphic.
101 //
102 // If a inline cache targets an interpreted method, then the
103 // G5 register will be used twice during the call. First,
104 // the call site will be patched to load a compiledICHolder
105 // into G5. (This is an ordered pair of ic_klass, method.)
106 // The c2i adapter will first check the ic_klass, then load
107 // G5_method with the method part of the pair just before
108 // jumping into the interpreter.
109 //
110 // Note that G5_method is only the method-self for the interpreter,
111 // and is logically unrelated to G5_megamorphic_method.
112 //
113 // Invariants on G2_thread (the JavaThread pointer):
114 // - it should not be used for any other purpose anywhere
115 // - it must be re-initialized by StubRoutines::call_stub()
116 // - it must be preserved around every use of call_VM
118 // We can consider using g2/g3/g4 to cache more values than the
119 // JavaThread, such as the card-marking base or perhaps pointers into
120 // Eden. It's something of a waste to use them as scratch temporaries,
121 // since they are not supposed to be volatile. (Of course, if we find
122 // that Java doesn't benefit from application globals, then we can just
123 // use them as ordinary temporaries.)
124 //
125 // Since g1 and g5 (and/or g6) are the volatile (caller-save) registers,
126 // it makes sense to use them routinely for procedure linkage,
127 // whenever the On registers are not applicable. Examples: G5_method,
128 // G5_inline_cache_klass, and a double handful of miscellaneous compiler
129 // stubs. This means that compiler stubs, etc., should be kept to a
