  "message": "[tint] Collapse nested subgroupMin/Max ops on AMD\n\nOn some AMD GPUs on Windows, nested subgroupMin/Max operations can\ntrigger a crash.\n\nThis change collapses multiple nested subgroupMin/Max calls to a single\ncall, the innermost subgroupMin/Max operation. This is safe because the\nresult of a subgroupMin/Max call is necessarily subgroup uniform.\n\nThis bug exists in both the Vulkan and D3D12 drivers on Windows, and on\nMac. On Windows it is fixed in later versions, but because it\u0027s a\nharmless optimizing transform it\u0027s applied broadly to all versions on\naffected backend platforms.\n\nBug: 508265321\nChange-Id: I658d0ddece1887d9211ad9ea2eb07a96ada0e3ce\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/311521\nCommit-Queue: Natalie Chouinard \u003cchouinard@google.com\u003e\nReviewed-by: dan sinclair \u003cdsinclair@chromium.org\u003e\n",
