Currently nsAtom::mString points to the interior of an nsStringBuffer. For static atoms this requires the use of nsFakeStringBuffer, which is pretty gross. This patch changes things so that nsAtom::mString points to a static char buffer for static atoms. This simplifies a number of things: - nsFakeStringBuffer and CheckStaticAtomSizes are no longer needed. - FakeBufferRefCountHelper is no longer needed. - nsAtom's constructor for static atoms is simpler. - RegisterStaticAtoms() is simpler. On the flip-side, a couple of things get more complicated. - nsAtom::ToString() treats static and dynamic atoms differently. - nsAtom::GetStringBuffer() is now only valid for dynamic atoms. This function is only used in two places, both involving DOMString, so those locations are updated appropriately. This also requires updating some other code assigning nsStrings to DOMStrings, because we can't assume that nsStrings are shared. On Linux64 this change reduces the size of the binary by 8752 B, and moves 81968 B from the .data to the .rodata section, where it can be shared between processes. --HG-- extra : rebase_source : 0f6fcdec1c525aa66222e208b66a9f9026f69bcb |
