if statements & difficulties using matrices vs vectors about loopvectorization.jl HOT 7 CLOSED

Attaching file with tests (just pull off the .txt required by Github to upload)

softmax3test.jl.txt

from loopvectorization.jl.

I'm working on these.

As a note

                # FIXME - would prefer to replace 2nd loop w/ if stmt
                # k <= maxk && (qq[i,k] = tmp)

Once it works, it'll probably be slower than the 2 loops, because it will evaluate the store on every iteration (but it'll apply a mask).

Thanks, @chriselrod!

Good to know about the if statement & two loops -- I'll keep them separate then.

I'm now testing basic conditionals and your softmax3 functions, based on the second (previously broken) version.

However, that FIXME wont work yet, because the library doesn't have much support for using the iterating variable for anything other than indexing.
(Also, FWIW, the 1 versions, with @avx on the inner loop, like you wrote, got slightly better performance.)

Oh, fantastic! Thanks, @chriselrod!

Closed because adding the store to the same loop has now been fixed and added to the testsuite.
