Subject: [x86] Add a bunch of test cases where we have different shuffle patterns
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7da57cf5b44afd5dc1860ac3374952e46b931380;p=oota-llvm.git

[x86] Add a bunch of test cases where we have different shuffle patterns
in the high and low 128-bit lanes of a v8f32 vector.

No functionality change yet, but wanted to set up the baseline for my
next patch which will make these quite a bit better. =]
