  "message": "Revert \"[utils] Adds Span::FillBytes as a workaround for ASAN timeouts.\"\n\nThis reverts commit d0dc9fd134a521b7e68605a7bc6769c273e3e51b.\n\nReason for revert: memset probably needs to be wrapped in unsafe.\n\nFailure Link: https://ci.chromium.org/ui/p/dawn/builders/ci/dawn-win-x64-builder-asan/3517/overview\n\nOriginal change\u0027s description:\n\u003e [utils] Adds Span::FillBytes as a workaround for ASAN timeouts.\n\u003e\n\u003e - In the bug below, we identified that as a part of spanification,\n\u003e   we updated some memset calls to std::ranges::fill. While this\n\u003e   was good for normal builds, this caused timeout issues in ASAN\n\u003e   builds because under ASAN std::ranges::fill obscures the loop\n\u003e   structure from the compiler\u0027s loop recognition. When dealing\n\u003e   with large buffers, this translates to billions of instrumented\n\u003e   stores causing timeouts.\n\u003e - This change introduces the Span::FillBytes helper that addresses\n\u003e   these timeouts by falling back to using memset when built for\n\u003e   ASAN.\n\u003e\n\u003e Bug: 545842615\n\u003e Change-Id: I431d16af99036cf8a2ba45ef173aa119e115804f\n\u003e Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/338335\n\u003e Commit-Queue: dan sinclair \u003cdsinclair@chromium.org\u003e\n\u003e Auto-Submit: Loko Kung \u003clokokung@google.com\u003e\n\u003e Reviewed-by: dan sinclair \u003cdsinclair@chromium.org\u003e\n\u003e Reviewed-by: Antonio Maiorano \u003camaiorano@google.com\u003e\n\nTBR\u003ddsinclair@chromium.org,amaiorano@google.com,dawn-scoped@luci-project-accounts.iam.gserviceaccount.com,lokokung@google.com\n\nNo-Presubmit: true\nNo-Tree-Checks: true\nNo-Try: true\nBug: 545842615\nChange-Id: I179f09ee41cd9d39ad1838653bc10a385f6f0be5\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/338775\nReviewed-by: Shrek Shao \u003cshrekshao@google.com\u003e\nReviewed-by: Kai Ninomiya \u003ckainino@chromium.org\u003e\nCommit-Queue: Kai Ninomiya \u003ckainino@chromium.org\u003e\nReviewed-by: Loko Kung \u003clokokung@google.com\u003e\nBot-Commit: rubber-stamper@appspot.gserviceaccount.com \u003crubber-stamper@appspot.gserviceaccount.com\u003e\n",
