  "message": "[DirectX] Expand {u,s}mul.with.overflow in DXILIntrinsicExpansion (#207297)\n\nDXIL has no op for the llvm.{u,s}mul.with.overflow intrinsics. These can\nbe emulated by performing the full multiply using double-width values\nand then checking the high-part of the result. However, this should be\navoided for 32-bit values since we don\u0027t want to make the shader start\nusing 64-bit values if it wasn\u0027t before. In this case we can use the\nUMul and IMul DXIL operations that return the result as separate low \u0026\nhigh values.\n\nWider (64-bit) multiplies, which can\u0027t widen further, compute the high\nhalf with same-width arithmetic instead.\n\nFixes #207090\n\n---------\n\nCo-authored-by: Copilot \u003c223556219+Copilot@users.noreply.github.com\u003e\nCo-authored-by: Farzon Lotfi \u003cfarzonl@gmail.com\u003e",
