  "message": "[M146] [tint] Fix loop analysis for limit cases\n\n\u003e We handled limit cases for \u003e\u003d and \u003c\u003d, but not for \u003e and \u003c.\n\u003e\n\u003e This causes us to add infinite loop mitigations for loops that store\n\u003e their bounds in a `let` (see the modified E2E tests), since we\n\u003e conservatively assume that the let may contain the problematic limit\n\u003e value. With some extra work we should be able to make the analysis\n\u003e avoid these false positives for common cases, but that will be left to\n\u003e a future CL.\n\u003e\n\u003e Fixed: 502206907\n\u003e Change-Id: I30224cdc47125e7603d3dc07daf0619c886f92e4\n\u003e Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/302776\n\u003e Reviewed-by: dan sinclair \u003cdsinclair@chromium.org\u003e\n\u003e Commit-Queue: James Price \u003cjrprice@google.com\u003e\n\n(cherry picked from commit 4bb845fa408205b58a060f2b474cecfdb3d53fe0)\n\nBug: 503211611, 502206907\nChange-Id: I30fd0f4bc8853f360201d2f2db6a07ae2cac1118\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/304117\nReviewed-by: dan sinclair \u003cdsinclair@chromium.org\u003e\nCommit-Queue: James Price \u003cjrprice@google.com\u003e\n",
