  "message": "[IVDesc] Fix off-by-one error in FindFirstIV ranges (#174441)\n\nConstantRange::getNonEmpty was excluding MAX and MAX - 1 in FindFirstIV\nvectorization, and this was discovered in an i1 miscompile, where it\nreturns the full range: fix it to exclude MAX only. The change has also\nnecessitated fixing a test that\u0027s not supposed to be vectorized.\n\nFixes #173459.\n\nCo-authored-by: Nikita Popov \u003cnpopov@redhat.com\u003e",
