C++ (Cpp) FencedLoad示例

示例#1

文件： backref.cpp 项目： Havoc/mangos-boost

void *getBackRef(BackRefIdx backRefIdx)
{
    // !backRefMaster means no initialization done, so it can't be valid memory
    // see addEmptyBackRefBlock for fences around lastUsed
    if (!FencedLoad((intptr_t&)backRefMaster)
        || backRefIdx.getMaster() > FencedLoad(backRefMaster->lastUsed)
        || backRefIdx.getOffset() >= BR_MAX_CNT)
        return NULL;
    return *(void**)((uintptr_t)backRefMaster->backRefBl[backRefIdx.getMaster()]
                     + sizeof(BackRefBlock)+backRefIdx.getOffset()*sizeof(void*));
}

示例#2

文件： large_objects.cpp 项目： jckarter/tbb

bool ExtMemoryPool::softCachesCleanup()
{
    // TODO: cleanup small objects as well
    return loc.regularCleanup(this, FencedLoad((intptr_t&)loCacheStat.age));
}

示例#3

文件： large_objects.cpp 项目： MarkusSR1984/Malloctest

bool LargeObjectCache::regularCleanup()
{
    return doCleanup(FencedLoad((intptr_t&)cacheCurrTime), /*doThreshDecr=*/false);
}

示例#4

{
    return doCleanup(FencedLoad((intptr_t&)cacheCurrTime), /*doThreshDecr=*/true);
}
