C++ (Cpp) cleanseInlineBits Examples

Example #1

File: BitVector.cpp Project: RobotsAndPencils/JavaScriptCore-iOS

void BitVector::mergeSlow(const BitVector& other)
{
    if (other.isInline()) {
        ASSERT(!isInline());
        *bits() |= cleanseInlineBits(other.m_bitsOrPointer);
        return;
    }
    
    ensureSize(other.size());
    ASSERT(!isInline());
    ASSERT(!other.isInline());
    
    OutOfLineBits* a = outOfLineBits();
    const OutOfLineBits* b = other.outOfLineBits();
    for (unsigned i = a->numWords(); i--;)
        a->bits()[i] |= b->bits()[i];
}
