示例1: ReleaseAllJITCode
JS_SetTopFrameAnnotation(JSContext *cx, void *annotation)
{
StackFrame *fp = cx->fp();
JS_ASSERT_IF(fp->beginsIonActivation(), !fp->annotation());
// Note that if this frame is running in Ion, the actual calling frame
// could be inlined or a callee and thus we won't have a correct |fp|.
// To account for this, ion::InvalidationBailout will transfer an
// annotation from the old cx->fp() to the new top frame. This works
// because we will never EnterIon on a frame with an annotation.
fp->setAnnotation(annotation);
JSScript *script = fp->script();
ReleaseAllJITCode(cx->runtime->defaultFreeOp());
// Ensure that we'll never try to compile this again.
JS_ASSERT(!script->hasIonScript());
script->ion = ION_DISABLED_SCRIPT;
