/* |

* Supported types for builtin functions. |
| 130 |
* |
| 131 |
* Types with -- for the two string fields are not permitted as argument types |
| 132 |
* in JS_DEFINE_TRCINFO. |
| 133 |
* |
| 134 |
* There are three kinds of traceable-native error handling. |
| 135 |
* |
| 136 |
* - If a traceable native's return type ends with _FAIL, it always runs to |
| 137 |
* completion. It can either succeed or fail with an error or exception; |
| 138 |
* on success, it may or may not stay on trace. There may be side effects |
| 139 |
* in any case. If the call succeeds but bails off trace, we resume in the |
| 140 |
* interpreter at the next opcode. |
| 141 |
* |
| 142 |
* _FAIL builtins indicate failure or bailing off trace by setting bits in |
| 143 |
* cx->interpState->builtinStatus. |
| 144 |
* |
| 145 |
* - If a traceable native's return type contains _RETRY, it can either |
| 146 |
* succeed, fail with a JS exception, or tell the caller to bail off trace |
| 147 |
* and retry the call from the interpreter. The last case happens if the |
| 148 |
* builtin discovers that it can't do its job without examining the JS |
| 149 |
* stack, reentering the interpreter, accessing properties of the global |
| 150 |
* object, etc. |
| 151 |
* |
| 152 |
* The builtin must detect the need to retry before committing any side |
| 153 |
* effects. If a builtin can't do this, it must use a _FAIL return type |
| 154 |
* instead of _RETRY. |
| 155 |
* |
| 156 |
* _RETRY builtins indicate failure with a special return value that |
| 157 |
* depends on the return type: |
| 158 |
* |
| 159 |
* BOOL_RETRY: JSVAL_TO_BOOLEAN(JSVAL_VOID) |
| 160 |
* INT32_RETRY: any negative value |
| 161 |
* STRING_RETRY: NULL |
| 162 |
* OBJECT_RETRY_NULL: NULL |
| 163 |
* JSVAL_RETRY: JSVAL_ERROR_COOKIE |
| 164 |
* |
| 165 |
* _RETRY function calls are faster than _FAIL calls. Each _RETRY call |
| 166 |
* saves two writes to cx->bailExit and a read from state->builtinStatus. |
| 167 |
* |
| 168 |
* - All other traceable natives are infallible (e.g. Date.now, Math.log). |
| 169 |
* |
| 170 |
* Special builtins known to the tracer can have their own idiosyncratic |
| 171 |
* error codes. |
| 172 |
* |
| 173 |
* When a traceable native returns a value indicating failure, we fall off |
| 174 |
* trace. If an exception is pending, it is thrown; otherwise, we assume the |
| 175 |
* builtin had no side effects and retry the current bytecode in the |
| 176 |
* interpreter. |
| 177 |
* |
| 178 |
* So a builtin must not return a value indicating failure after causing side |
| 179 |
* effects (such as reporting an error), without setting an exception pending. |
| 180 |
* The operation would be retried, despite the first attempt's observable |
| 181 |
* effects. |

/* |

* This macro is used for builtin functions that can be called from JITted |
| 271 |
* code. It declares a C function named <op> and a CallInfo struct named |
| 272 |
* <op>_ci so the tracer can call it. The <N> in JS_DEFINE_CALLINFO_<N> is |
| 273 |
* the number of arguments the builtin takes. Builtins with no arguments |
| 274 |
* are not supported. Using a macro is clunky but ensures that the types |
| 275 |
* for each C function matches those for the corresponding CallInfo struct; |
| 276 |
* mismatched types can cause subtle problems. |
| 277 |
* |
| 278 |
* The macro arguments are: |
| 279 |
* |
| 280 |
* - The linkage for the function and the associated CallInfo global. It |
| 281 |
* can be extern, static, or FRIEND, which specifies JS_FRIEND_API linkage |
| 282 |
* for the function. |
| 283 |
* |
| 284 |
* - The return type. This identifier must name one of the _JS_TYPEINFO_* |
| 285 |
* macros defined in jsbuiltins.h. |
| 286 |
* |
| 287 |
* - The builtin name. |
| 288 |
* |
| 289 |
* - The parameter types. |
| 290 |
* |
| 291 |
* - The cse flag. 1 if the builtin call can be optimized away by common |
| 292 |
* subexpression elimination; otherwise 0. This should be 1 only if the |
| 293 |
* function is idempotent and the return value is determined solely by the |
| 294 |
* arguments. |
| 295 |
* |
| 296 |
* - The fold flag. Reserved. The same as cse for now. |
