flavors of floating point semantics.
Just 2 days ago a colleague had a clever implementation of something he
needed to do in gecko gfx code, and had to
Can somebody get us less-circumstantial evidence that the stuff from

Totally agree that 1% is probably still too much to drop, but the 4x drop
over the past two years makes me hopeful that we'll be able to drop
non-SSE2, eventually.
SSE2 is not just about SIMD. The most important thing it buys us IMHO is to
be able to not use x87 instructions anymore and instead us
What does requiring SSE2 buy us? 1% of hundreds of millions of Firefox
