[PATCH] D125747: [RISCV] Enable scalable vectorization by default for RVV

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

Downstream we have had to patch a lot of TTI functions to avoid crashing with scalable vectors. So I'm also thinking we're not ready for this to be enabled by default. I've been meaning to try and find some solid test cases to show this off but I agree with @reames .
