// Exported via the XLA HLO Importer
// The resulting MLIR was modified by hand by changing all large constants to be
// splats of 0.42, removing the leading "module" wrapper, removing "name"
// attributes, removing extraneous 0s from float constants, and cleaning up
// extra whitespace. On top of that, the result was further trimmed by removing
// some calls from @main and the call graphs of the removed callees.
