Arquivo: jsdbgapi.cpp Projeto: funkaster/Spidermonkey-1

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;
