  "message": "[tint][hlsl] Only polyfill trunc on FXC\n\nThe HLSL polyfill for trunc was added in:\nhttps://dawn-review.googlesource.com/c/dawn/+/125420\nto work around an FXC bug, but causes issues on newer Intel devices\nusing DXC, which have different flushing to zero behavior for subnormals\n(see https://crbug.com/42251226), which then affects the polyfill of\nremainder causing incorrect values for some f16 cases.\n\nWe can avoid this affecting remainder on Intel by limiting the polyfill\nof trunc to FXC where it\u0027s actually needed.\n\nAs a follow up we should confirm whether there is a driver issue on\nIntel that still needs to be covered by a new CTS test for use of\nfloor/ceil directly in WGSL.\n\nBug: 390458364\nChange-Id: I79aec18393afa19f3c9047dd3ecaed0d6a6a6964\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/302655\nReviewed-by: dan sinclair \u003cdsinclair@chromium.org\u003e\nCommit-Queue: Natalie Chouinard \u003cchouinard@google.com\u003e\n",
