It is rare to report an error in BackendUtil.cpp . So I checked the other Diags.Report instance and noticed that -split-dwarf-file a.dwo -split-dwarf-output a.dwo (when a.dwo is not writable) suppresses the output. So there is no reason that -fbasic-block-sections=list= should not follow the convention.
