GlobalObject.h Global object slots are reserved as follows: [0, APPLICATION_SLOTS) Pre-reserved slots in all global objects set aside for the embedding's use. As with all reserved slots these start out as UndefinedValue() and are traced for GC purposes. Apart from that the engine never touches these slots, so the embedding can do whatever it wants with them. [APPLICATION_SLOTS, APPLICATION_SLOTS + JSProto_LIMIT) Stores the original value of the constructor for the corresponding JSProtoKey. [APPLICATION_SLOTS + JSProto_LIMIT, APPLICATION_SLOTS + 2 * JSProto_LIMIT) Stores the prototype, if any, for the constructor for the corresponding JSProtoKey offset from JSProto_LIMIT. [APPLICATION_SLOTS + 2 * JSProto_LIMIT, RESERVED_SLOTS) Various one-off values: ES5 13.2.3's [[ThrowTypeError]], RegExp statics, the original eval for this global object (implementing |var eval = otherWindow.eval; eval(...)| as an indirect eval), a bit indicating whether this object has been cleared (see JS_ClearScope), and a cache for whether eval is allowed (per the global's Content Security Policy). The two JSProto_LIMIT-sized ranges are necessary to implement js::FindClassObject, and spec language speaking in terms of "the original Array prototype object", or "as if by the expression new Array()" referring to the original Array constructor. The actual (writable and even deletable) Object, Array, &c. properties are not stored in reserved slots. 36632

List.h The List specification type, ECMA-262 6.2.1. <https://tc39.github.io/ecma262/#sec-list-and-record-specification-type> Lists are simple mutable sequences of values. Many standards use them. Abstractly, they're not objects; they don't have properties or prototypes; they're for internal specification use only. ListObject is our most direct implementation of a List: store the values in the slots of a JSObject. We often implement Lists in other ways. For example, builtin/Utilities.js contains a completely unrelated List constructor that's used in self-hosted code. And AsyncGeneratorObject optimizes away the ListObject in the common case where its internal queue never holds more than one element. ListObjects must not be exposed to content scripts. 3013

MallocProvider.h Hierarchy of SpiderMonkey system memory allocators: - System {m,c,re}alloc/new/free: Overridden by jemalloc in most environments. Do not use these functions directly. - js_{m,c,re}alloc/new/free: Wraps the system allocators and adds a failure injection framework for use by the fuzzers as well as templated, typesafe variants. See js/public/Utility.h. - AllocPolicy: An interface for the js allocators, for use with templates. These allocators are for system memory whose lifetime is not associated with a GC thing. See js/public/AllocPolicy.h. - SystemAllocPolicy: No extra functionality over bare allocators. - TempAllocPolicy: Adds automatic error reporting to the provided JSContext when allocations fail. - ZoneAllocPolicy: Forwards to the Zone MallocProvider. - MallocProvider. A mixin base class that handles automatically updating the GC's state in response to allocations that are tied to a GC lifetime or are for a particular GC purpose. These allocators must only be used for memory that will be freed when a GC thing is swept. - gc::Zone: Automatically triggers zone GC. - JSRuntime: Automatically triggers full GC. - JSContext: Dispatches directly to the runtime. 8098

Probes-inl.h Many probe handlers are implemented inline for minimal performance impact, especially important when no backends are enabled. 2446
Probes.cpp These functions call the DTrace macros for the JavaScript USDT probes. Originally this code was inlined in the JavaScript code; however since a number of operations are called, these have been placed into functions to reduce any negative compiler optimization effect that the addition of a number of usually unused lines of code would cause. 2119
Probes.h Static probes The probe points defined in this file are scattered around the SpiderMonkey source tree. The presence of probes::SomeEvent() means that someEvent is about to happen or has happened. To the extent possible, probes should be inserted in all paths associated with a given event, regardless of the active runmode (interpreter/traceJIT/methodJIT/ionJIT). When a probe fires, it is handled by any probe handling backends that have been compiled in. By default, most probes do nothing or at least do nothing expensive, so the presence of the probe should have negligible effect on running time. (Probes in slow paths may do something by default, as long as there is no noticeable slowdown.) For some probes, the mere existence of the probe is too expensive even if it does nothing when called. For example, just having consistent information available for a function call entry/exit probe causes the JITs to de-optimize function calls. In those cases, the JITs may query at compile time whether a probe is desired, and omit the probe invocation if not. If a probe is runtime-disabled at compilation time, it is not guaranteed to fire within a compiled function if it is later enabled. Not all backends handle all of the probes listed here. 4310

The implementation in JSObject is incorrect for proxies since it doesn't take account of the handler type. 5617
Realm-inl.h static 3486
Realm.cpp As a hack, we clear our timezone cache every time we create a new realm. This ensures that the cache is always relatively fresh, but shouldn't interfere with benchmarks that create tons of date objects (unless they also create tons of iframes, which seems unlikely). 25277
Realm.h A single-entry cache for some base-10 double-to-string conversions. This helps date-format-xparb.js. It also avoids skewing the results for v8-splay.js when measured by the SunSpider harness, where the splay tree initialization (which includes many repeated double-to-string conversions) is erroneously included in the measurement; see bug 562553. 31529

SharedArrayObject.h SharedArrayRawBuffer A bookkeeping object always stored immediately before the raw buffer. The buffer itself is mmap()'d and refcounted. SharedArrayBufferObjects and structured clone objects may hold references. |<------ sizeof ------>|<- length ->| | waste | SharedArrayRawBuffer | data array | waste | Observe that if we want to map the data array on a specific address, such as absolute zero (bug 1056027), then the SharedArrayRawBuffer cannot be prefixed to the data array, it has to be a separate object, also in shared memory. (That would get rid of ~4KB of waste, as well.) Very little else would have to change throughout the engine, the SARB would point to the data array using a constant pointer, instead of computing its address. If preparedForWasm_ is true then length_ can change following initialization; it may grow toward maxSize_. See extensive comments above WasmArrayRawBuffer in ArrayBufferObject.cpp. length_ only grows when the lock is held. 10696

The locking mechanism is dead-simple and coarse grained: a single lock guards all of the internal table itself, the table's entries, and the entries' reference counts.

The differences between our implementation and the spec are minor: - We call the two phases "write" and "read". - Our algorithms use an explicit work stack, rather than recursion. - Serialized data is a flat array of bytes, not a (possibly cyclic) graph of "Records". - As a consequence, we handle non-treelike object graphs differently. We serialize objects that appear in multiple places in the input as backreferences, using sequential integer indexes. See `JSStructuredCloneReader::allObjs`, our take on the "memory" map in the spec's StructuredDeserialize. 113781

TraceLogging.cpp 53803
TraceLogging.h [SMDOC] Tracelogging overview. Tracelogging makes it possible to trace the occurrence of a single event and/or the start and stop of an event. This is implemented with as low overhead as possible to not interfere with running. Logging something is done in 3 stages. 1) Get the tracelogger of the current thread. cx may be omitted, in which case it will be fetched from TLS. - TraceLoggerForCurrentThread(cx); 2) Optionally create a TraceLoggerEvent for the text that needs to get logged. This step takes some time, so try to do this beforehand, outside the hot path and don't do unnecessary repetitions, since it will cripple performance. - TraceLoggerEvent event(logger, "foo"); There are also some predefined events. They are located in TraceLoggerTextId. They don't require to create an TraceLoggerEvent and can also be used as an argument to these functions. 3) Log the occurrence of a single event: - TraceLogTimestamp(logger, TraceLoggerTextId); Note: it is temporarily not supported to provide an TraceLoggerEvent as argument to log the occurrence of a single event. or log the start and stop of an event: - TraceLogStartEvent(logger, TraceLoggerTextId); - TraceLogStartEvent(logger, TraceLoggerEvent); - TraceLogStopEvent(logger, TraceLoggerTextId); - TraceLogStopEvent(logger, TraceLoggerEvent); or the start/stop of an event with a RAII class: - AutoTraceLog atl(logger, TraceLoggerTextId); - AutoTraceLog atl(logger, TraceLoggerEvent); 21092
TraceLoggingGraph.cpp 17953
TraceLoggingGraph.h The output of a tracelogging session is saved in /tmp/tl-data.json. The format of that file is a JS array per tracelogger (=thread), with a map containing: - dict: Name of the file containing a json table with the log text. All other files only contain a index to this table when logging. - events: Name of the file containing a flat list of log events saved in binary format. (64bit: Time Stamp Counter, 32bit index to dict) - tree: Name of the file containing the events with duration. The content is already in a tree data structure. This is also saved in a binary file. - treeFormat: The format used to encode the tree. By default "64,64,31,1,32". There are currently no other formats to save the tree. - 64,64,31,1,32 signifies how many bytes are used for the different parts of the tree. => 64 bits: Time Stamp Counter of start of event. => 64 bits: Time Stamp Counter of end of event. => 31 bits: Index to dict file containing the log text. => 1 bit: Boolean signifying if this entry has children. When true, the child can be found just right after this entry. => 32 bits: Containing the ID of the next event on the same depth or 0 if there isn't an event on the same depth anymore. /-> The position in the file. Id is this divided by size of entry. | So in this case this would be 1 (192bits per entry). | /-> Indicates there are children. The | | first child is located at current | | ID + 1. So 1 + 1 in this case: 2. | | Or 0x00180 in the tree file. | | /-> Next event on the same depth is | | | located at 4. So 0x00300 in the | | | tree file. 0x0000C0: [start, end, dictId, 1, 4] Example: 0x0: [start, end, dictId, 1, 0] | /----------------------------------\ | | 0xC0: [start, end, dictId, 0, 2] 0x180 [start, end, dictId, 1, 0] | /----------------------------------\ | | 0x240: [start, end, dictId, 0, 4] 0x300 [start, end, dictId, 0, 0] 9182
