> How are the bits numbered in there, IOW is bit 0 always the LSB or not?
Answering to myself: no, they are numbered in memory order, which is
problematic because, in the implementation model, stand-alone

Thanks. The problem is indeed the BIT_FIELD_REF of a scalar, which is an
undocumented extension of GENERIC:

dst$val_9 = _1;
_2 = BIT_FIELD_REF ;
_3 = _2 & 64;
if (_3 != 0)
