  "message": "[dawn] Make BitSetRangeIterator::Advance simpler to reason about\n\nThe calls to ScanForwardAndShiftBits with mBits inversion interspersed\nmade it difficult to reason about what\u0027s happening. The second call\nto ScanForwardAndShiftBits before the last mBits inversion introduced\nextra 1 bits on the left that had to be cleaned up.\n\nInstead inline ScanForwardAndShiftBits and use countr_one instead of\nshifting all of mBits. Finally guard the loop to run only when the\nbitset has more than 64 bits.\n\nSimplifies test code mildly.\n\nBug: None\nChange-Id: I81ad70f799e287e980fd1e994b239ec2f1c31e5c\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/244815\nReviewed-by: Shaobo Yan \u003cshaoboyan@microsoft.com\u003e\nReviewed-by: Geoff Lang \u003cgeofflang@chromium.org\u003e\nAuto-Submit: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Corentin Wallez \u003ccwallez@chromium.org\u003e\n",
