; The old SPIRVEmitNonSemanticDI MachineFunctionPass emitted DebugSource and
; DebugCompilationUnit instructions as MachineInstructions, which were tested via
; --print-after=spirv-nonsemantic-debug-info (CHECK-MIR prefix).
; SPIRVNonSemanticDebugHandler replaces that pass. It emits NSDI instructions
; directly as MCInsts at print time, with no MIR representation. CHECK-SPIRV
; tests the same instructions at the SPIR-V text output level.
