  "message": "[Codegen][LLVMCPU] Hoist in-loop stack alloca (#24749)\n\n`HALDispatchABI::loadProcessorData` built its CPU-feature patch buffer\nwith an `alloca` at the ukernel call site instead of the function entry\nblock. `RewriteCallOpABI` materializes this after all MLIR-\u003eLLVM\nconversions are done, so no later pass can hoist it out of a loop if the\ncall happens to sit inside one, causing the stack to grow unboundedly on\nlarge matmuls.\n\nThe computation only depends on the function\u0027s `environment` argument\nand static target attributes, so it can safely move to the entry block.\n\nFixes #24744\n\n---------\n\nSigned-off-by: Federico Bruzzone \u003cfederico.bruzzone.i@gmail.com\u003e",
