[cfe-commits] [PATCH] Optimize vec3 loads/stores

[Sean Silva]

I know vectors aren't part of C11/C++11, but doesn't this violate the
memory model? In particular, doesn't it introduce spurious stores?

Forgive me if there's some context behind this that I'm missing which
makes this concern irrelevant.
