[PATCH] D88154: Initial support for vectorization using Libmvec (GLIBC vector math library).

[Venkataramanan Kumar via Phabricator via cfe-commits]

venkataramanan.kumar.llvm updated this revision to Diff 297925.
venkataramanan.kumar.llvm added a comment.

Updated the patch as per review comments received.

The test cases are updated the checks based on the below comment from Francesco.

---Snip--
I think you are over-testing here. It is enough to check that inside the vector body there is a call to the vector function you have listed in the mapping.
---Snip--  
Florian also suggesting the same.

I still use metadata suggested by Sanjay . Currently testing only VF=4 . This is because we have float and double type lib calls in the test case and libmvec has vector call support for VF=4 .    For VF say 8  there is vector call support for double types.

I can add few more test with meta data to cover floats with VF=8.   please let me know your suggestions.
