Subject: [VPlan] Add printOperands helper to VPUser (NFC).
X-Git-Tag: llvmorg-13-init~6721
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=091c5c9a187f656a62f28b6c43d25bfb25c9107e;p=platform%2Fupstream%2Fllvm.git

[VPlan] Add printOperands helper to VPUser (NFC).

Factor out the code for printing operands of a VPUser so it can be
re-used when printing other recipes.
