This array holds either the current argument value or the magic
forwarding value. The latter means that the function has both a
CallObject and an ArgumentsObject AND the particular formal variable is
aliased by the CallObject. In such cases, the CallObject holds the
canonical value so any element access to the arguments object should load
the value out of the CallObject (which is pointed to by MAYBE_CALL_SLOT).

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.

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.

Many probe handlers are implemented inline for minimal performance impact,
especially important when no backends are enabled.
|
2362 |
| 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.
|
2208 |
| 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.

SharedArrayRawBuffer
A bookkeeping object always stored before the raw buffer. The buffer itself
is refcounted. SharedArrayBufferObjects and structured clone objects may hold
references.
WasmSharedArrayRawBuffer is a derived class that's used for Wasm buffers.
- Non-Wasm buffers are allocated with a single calloc allocation, like this:
|<------ sizeof ------>|<- length ->|
| SharedArrayRawBuffer | data array |
- Wasm buffers are allocated with MapBufferMemory (mmap), like this:
|<-------- sizeof -------->|<- length ->|
| waste | WasmSharedArrayRawBuffer | 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 {Wasm}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.
For Wasm buffers, length_ can change following initialization; it may grow
toward sourceMaxPages_. See extensive comments above WasmArrayRawBuffer in
ArrayBufferObject.cpp. length_ only grows when the lock is held.

The `SharedImmutableStringsCache` allows safely sharing and deduplicating
immutable strings (either `const char*` [any encoding, not restricted to
only Latin-1 or only UTF-8] or `const char16_t*`) between threads.
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. It is only safe to perform any mutation on the cache or any
data stored within the cache when this lock is acquired.

This file implements the structured data algorithms of
https://html.spec.whatwg.org/multipage/structured-data.html
The spec is in two parts:
- StructuredSerialize examines a JS value and produces a graph of Records.
- StructuredDeserialize walks the Records and produces a new JS value.
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.
