[PATCH] D86519: [SystemZ] New pass for domain reassignment from integer to vector.

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa updated this revision to Diff 299336.
jonpa added a comment.

Patch still experimental.

Latest improvements include:

- only do a reassignment when it seems beneficial (given the number of live virtual regs)
- managed to enable MachineCSE for the generated VLEI instructions.
