  "message": "[roll] Roll fuchsia [profiler] Add unwinding mechanism to stack sampler\n\nThe profiler now performs a full stack unwind instead of just capturing\nraw stack memory. This change enables the collection of Program Counter\n(PC) sequences for each sampled thread, providing structured call\nstacks.\n\nKey improvements include:\n* Introduced a BufferedStackMemory class to manage memory reads and\n  dynamically capture stack chunks during the unwinding process.\n* Implemented a mechanism to capture restricted states,\n  enabling the unwinder to do the Starnix-to-Android transition.\n\nOriginal-Bug: 483770015\nOriginal-Reviewed-on: https://fuchsia-review.googlesource.com/c/fuchsia/+/1483567\nOriginal-Revision: bb80e35bd9dd5b7544b9c346ed94355717d6a0d3\nGitOrigin-RevId: 78ac2e509919f53468e380e387fbe67756cbeaed\nChange-Id: I65aae5cf7373f138ef08f062284c913954f71886\n",
