To get the data flow yes, but of course the FRE issue is that the SSO attribution is lost and we generate wrong code, so actual SSO attribution is needed for that. I was mostly questioning SSO on bitfields given bitfield layout might be special. I suppose avoiding padding in S0 might make this more portable (so signed/unsigned char for f7/f6). The testcase fails with that as well before the fix.
