  "message": "[uniformity] relax uniformity when loop bodies have returns\n\nSee https://github.com/gpuweb/gpuweb/issues/5364\n\nWhen a loop body has a return then it can cut off control flow\nentirely. Function calls that might have required uniformity\nmay no longer be reached, and should not cause a uniformity error.\n\nAlso, the return may be taken non-uniformly, and hence the other\nremaining invocations may complete the loop nonuniformily. In these\ncases code after the loop may now be exposed to nonuniform execution,\nwhich should trigger a uniformity error.\n\nThe tests add a small domain-specific language to test various\ncombinations of statement behaviours (break, return, next, continue)\nand various placements of uniformity \"attackers\" and \"detectors\".\n\nThis patch is part 1: loop without continuing.\n\nThis includes 4 cases that fail due to the conservatism.\n\n// \"\", \"_#b!\", \"\", \"\"\n// \"\", \"_#r!\", \"\", \"\"\n// \"\", \"_#b\u003dr!\", \"\", \"\"\n// \"\", \"_#bxr!\", \"\", \"\"\n\nBug: 452692768\nChange-Id: I6a6a696457f17dfa3be4e0c2fecd895bd058c254\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/272156\nReviewed-by: Alan Baker \u003calanbaker@google.com\u003e\nCommit-Queue: David Neto \u003cdneto@google.com\u003e\n",
