[PATCH] D67148: [LoopVectorize][PowerPC] Estimate int and float register pressure separately in loop-vectorize

[Zixuan Wu (Zeson) via Phabricator via llvm-commits]

wuzish updated this revision to Diff 220278.
wuzish added a comment.

Address comments to simplify the default implementation for targets.

Use 1 and 0 to represent default register classes for vector and scalar type to keep other targets behavior as before.
Targets can reimplement it like PowerPC.
