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

[Benyei, Guy]

Hi Tanya,
Looks good and usefull, but I'm not sure if it should be clang's decision if storing and loading vec4s is better than vec3.
Anyhow, shouldn't the test check the store shuffle too?

Thanks
    Guy

This patch treats vectors of size 3 like size 4 when loading and store which in turn will cause more optimal code to be emitted by the backend. I've included a test case.

Please review.

Thanks,
Tanya
