Error when looping over function call about loopvectorization.jl HOT 2 CLOSED

Thanks for this bug report.

I realize that 0.4 introduced a major breaking change.
Now, instead of transforming a loop, @avx describes a loop and passes the description to a generated function.
Unless I'm mistaken, a generated function defined within LoopVectorization will only be able to call functions defined within LoopVectorization or its dependencies.

To get the old behavior, you can use @_avx.

Although, the old behavior was also broken...
For now, you can try

vmap!(xi -> clenshaw(xi, coef), y, x)

I'll leave this issue open until I fix @_avx. The problem is that it's trying to use LoopVectorization.clenshaw instead of Main.clenshaw.

from loopvectorization.jl.

I added your problem to the tests using the @_avx macro.
