// precompiled-dxil.slang

// A test that uses slang-modules with embedded precompiled DXIL.
// The test compiles both library slang (export-library.slang) to a slang-module using -embed-downstream-ir.
// The result is linked together with this module (precompiled-dxil.slang) in a second slangc invocation.
// Internally, slang does not use the IR in the modules to link, but rather their embedded DXIL.
// The test passes if there is no errror thrown.
// TODO: Check if final linkage used only the precompiled dxil.
