[PATCH] D96028: [RISCV] Add patterns for scalable-vector fabs & fcopysign

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck updated this revision to Diff 321419.
frasercrmck added a comment.

- add support for when the sign is trunc'd or extended from a different type
- we could probably improve some of the code generation in this case (fneg isn't caught)
