[LLVMdev] Is there any llvm neon intrinsic that maps to vmla.f32 instruction ?

In that case, you must disable the pass when you call the back-end.

[LLVMdev] Is there any llvm neon intrinsic that maps to vmla.f32 instruction ?
Hi Renato,
Thanks for the answer, it confirms what I was suspecting. My problem is that this behavior is controlled by vmlx forwarding on cortex-a9 for which despite asking on this list, I couldn't get a clear understanding what this option is meant for.
So here are my new questions:
Why for cortex-a9 vmlx-forwarding is enabled by default ? Is it to guarantee correctness or for performance
