 > > From what I can see of the geode-gcc-4.2.patch on gnashdev.org, it
 does not do anything for the two new geode-specific 3dnow instructions,
 which include the very useful inverse sqrt.  Shall I take a look to see if
 it's in gcc 4.3 at all, and try my hand at pulling it into the patch, or
 adding a peephole optimization for it if it isn't supported in gcc yet?

 The patch was originally developed for the Geode GX, so yes, it would be a
 good idea to add this instruction as I believe it'll help performance on
 the LX.
