I think you mean "swap without a temporary register". On other platforms, we need to allocate a register, and avoid conflicts with other allocated registers.

It looks funny, at first glance, to assign from something called "allocated registers" into something called "freeRegister". how about renaming "freeRegister" to "pushedRegister"?

Should we call this "attributeValueTestingRequiresCaseFoldingRegister"?
> Source/WebCore/cssjit/SelectorCompiler.cpp:1172 > + // We make the assumption that name matching fails in most case and we keep value matching outside
"cases"
> Source/WebCore/cssjit/SelectorCompiler.cpp:1189 > + if (attributeSelector.m_match == CSSSelector::Exact)
Can we make this an ASSERT?
