* 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: JSVAL_TO_BOOLEAN(JSVAL_VOID)
* INT32_RETRY: any negative value
* STRING_RETRY: NULL
* OBJECT_RETRY_NULL: NULL
* JSVAL_RETRY: JSVAL_ERROR_COOKIE
*
* _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 cse flag. 1 if the builtin call can be optimized away by common
* subexpression elimination; otherwise 0. This should be 1 only if the
* function is idempotent and the return value is determined solely by the
* arguments.
*
* - The fold flag. Reserved. The same as cse for now.
