* css/CSSRule.cpp:
(WebCore::CSSRule::reportMemoryUsage): we manually implement polymorphic
call here to avoid adding vtable pointer to all CSSRule objects. Descendants
are expected to report their memory via reportDescendantMemoryUsage. The name
is intentionally different from reportMemoryUsage to avoid accidential infitite
recursion: if the descendants overrode non-virtual CSSRule::reportMemoryUsage,
it would be easy to add a new descendant type to the switch in
CSSRule::reportMemoryUsage without providing proper override for reportMemoryUsage
and CSSRule::reportMemoryUsage would end up calling itself.
(WebCore):
(WebCore::CSSRule::reportBaseClassMemoryUsage): again we cannot use
MemoryClassInfo::visitBaseClass like we do for virtual methods because it would
lead to a recursive call of CSSRule::reportMemoryUsage. This is why we use
reportBaseClassMemoryUsage to allow descendants to report objects referenced
from their base class.
