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

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/CodeGen/CodeGenPrepare.cpp:573
       // Restart BB iteration if the dominator tree of the Function was changed
       if (ModifiedDTOnIteration)
         break;
----------------
Before introducing limits, can we try to remove this case? That is, continue simplifying the rest of the blocks before we start a new iteration? I expect that the current implementation looks like this to avoid some iterator invalidation issues, but there's probably a way to avoid that with a bit more effort.
