[PATCH] D129352: [CodeGen] Limit building time for CodeGenPrepare

[Xiang Zhang via Phabricator via llvm-commits]

xiangzhangllvm updated this revision to Diff 446014.
xiangzhangllvm added a comment.

Refine:
1 Add SetVector FreshBBs to trace the BBs need to be optimized.
2 Add enum ModifyDT {  NotModifyDT,  ModifyBBDT,  ModifyInstDT } to spilt out the iteration for instruction in single BB.
3 Modify some operations to re-optimized updated BBs

(All lit tests pass, my local big case still works well: 30mins --> 5 mins)
