* See ValidateWriter::checkAccSet() for what each of these access regions
* mean.
*
* *** WARNING WARNING WARNING ***
*
* Any incorrect access region annotations on loads/stores/calls could lead to
* subtle bugs that manifest rarely, eg. when two loads are CSE'd that
* shouldn't be.
*
* If you add a new access region you will need to add some sanity checking to
* ValidateWriter::checkAccSet(). Do not skimp on this checking! Make it as
* strong as you can. Look at the existing cases for inspiration. This
* checking helps prevent these subtle bugs.
*
* Furthermore, do not add a "catch-all" region such as "ACCSET_OTHER". There
* are two reasons for this. First, no checking could be done on loads/stores
* bearing it. Second, it would be too easy for someone in the future who
* doesn't understand how AccSets work to use it inappropriately. Only
* ACCSET_ALL (the union of all access regions) should be used as a catch-all,
* it can always be used safely, but it reduces optimization possibilities.
*
* Most of the access regions are type-based, ie. all structs of a particular
* type combined together form a region. This is less precise than
* considering each struct separately, but also much simpler.
*
* - ACCSET_STATE: The TracerState struct.
* - ACCSET_STACK: The stack.
* - ACCSET_RSTACK: The return stack.
* - ACCSET_CX: All JSContext structs.
* - ACCSET_EOS: The globals area.
* - ACCSET_ALLOC: All memory blocks allocated with LIR_allocp (in
* other words, this region is the AR space).
* - ACCSET_FRAMEREGS: All JSFrameRegs structs.
* - ACCSET_STACKFRAME: All JSStackFrame objects.
* - ACCSET_RUNTIME: The JSRuntime object.
* - ACCSET_OBJ_CLASP: The 'clasp' field of all JSObjects.
* - ACCSET_OBJ_SHAPE: The 'shape' field of all JSObjects.
* - ACCSET_OBJ_PROTO: The 'proto' field of all JSObjects.
* - ACCSET_OBJ_PARENT: The 'parent' field of all JSObjects.
* - ACCSET_OBJ_PRIVATE: The 'private' field of all JSObjects.
* - ACCSET_OBJ_CAPACITY: The 'capacity' field of all JSObjects.
* - ACCSET_OBJ_SLOTS: The 'slots' field of all JSObjects.
* - ACCSET_SLOTS: The slots (be they fixed or dynamic) of all JSObjects.
* - ACCSET_TARRAY: All TypedArray structs.
* - ACCSET_TARRAY_DATA: All TypedArray data arrays.
* - ACCSET_ITER: All NativeIterator structs.
* - ACCSET_ITER_PROPS: The props_arrays of all NativeIterator structs.
* - ACCSET_STRING: All JSString structs.
* - ACCSET_STRING_MCHARS: All JSString mchars arrays.
* - ACCSET_TYPEMAP: All typemaps form a single region.
* - ACCSET_FCSLOTS: All fcslots arrays form a single region.
* - ACCSET_ARGS_DATA: All Arguments data arrays form a single region.

* Supported types for builtin functions.
*
* Types with -- for the two string fields are not permitted as argument types
* in JS_DEFINE_TRCINFO.
*
* There are three kinds of traceable-native error handling.
*
* - If a traceable native's return type ends with _FAIL, it always runs to
* completion. It can either succeed or fail with an error or exception;
* on success, it may or may not stay on trace. There may be side effects
* in any case. If the call succeeds but bails off trace, we resume in the
* interpreter at the next opcode.
*
* _FAIL builtins indicate failure or bailing off trace by setting bits in
* cx->interpState->builtinStatus.
*
* - If a traceable native's return type contains _RETRY, it can either
* succeed, fail with a JS exception, or tell the caller to bail off trace
* and retry the call from the interpreter. The last case happens if the
* builtin discovers that it can't do its job without examining the JS
* stack, reentering the interpreter, accessing properties of the global
* object, etc.
*
* The builtin must detect the need to retry before committing any side
* effects. If a builtin can't do this, it must use a _FAIL return type
* instead of _RETRY.
*
* _RETRY builtins indicate failure with a special return value that
* depends on the return type:
*
* BOOL_RETRY: JS_NEITHER
* INT32_RETRY: any negative value
* STRING_RETRY: NULL
* OBJECT_RETRY_NULL: NULL
*
* _RETRY function calls are faster than _FAIL calls. Each _RETRY call
* saves two writes to cx->bailExit and a read from state->builtinStatus.
*
* - All other traceable natives are infallible (e.g. Date.now, Math.log).
*
* Special builtins known to the tracer can have their own idiosyncratic
* error codes.
*
* When a traceable native returns a value indicating failure, we fall off
* trace. If an exception is pending, it is thrown; otherwise, we assume the
* builtin had no side effects and retry the current bytecode in the
* interpreter.
*
* So a builtin must not return a value indicating failure after causing side
* effects (such as reporting an error), without setting an exception pending.
* The operation would be retried, despite the first attempt's observable
* effects.

/*
* This macro is used for builtin functions that can be called from JITted
* code. It declares a C function named <op> and a CallInfo struct named
* <op>_ci so the tracer can call it. The <N> in JS_DEFINE_CALLINFO_<N> is
* the number of arguments the builtin takes. Builtins with no arguments
* are not supported. Using a macro is clunky but ensures that the types
* for each C function matches those for the corresponding CallInfo struct;
* mismatched types can cause subtle problems.
*
* The macro arguments are:
*
* - The linkage for the function and the associated CallInfo global. It
* can be extern, static, or FRIEND, which specifies JS_FRIEND_API linkage
* for the function.
*
* - The return type. This identifier must name one of the _JS_TYPEINFO_*
* macros defined in jsbuiltins.h.
*
* - The builtin name.
*
* - The parameter types.
*
* - The isPure flag. Set to 1 if:
* (a) the function's return value is determined solely by its arguments
* (ie. no hidden state, no implicit inputs used such as global
* variables or the result of an I/O operation); and
* (b) the function causes no observable side-effects (ie. no writes to
* global variables, no I/O output).
* Multiple calls to a pure function can be merged during CSE.
*
* - The storeAccSet. This indicates which memory access regions the function
* accesses. It must be ACCSET_NONE if the function is pure; use
* ACCSET_STORE_ANY if you're not sure. Used to determine if each call site
* of the function aliases any loads.
