Currently, the ClangIR pipeline emits certain DINodes regardless of whether the -g option is specified. This occurs because the LLVM translation process automatically collects debug information from FusedLoc and other well-known constructs in the LLVM dialect, leading to their emission.

I haven't found any option to disable this behavior directly. A straightforward solution is to strip the debug information from the final LLVM module, similar to opt -strip-debug.

Stripping would probably cost even more build time, perhaps the LLVM translation process could be made flexible instead and we'd get it for free
