I guess it's because constant prop. Could you try the following change

- if (sc == SHF_SC_L_SHF)
+ if (sc == SHF_SC_L_SHF && shift)
shift = 32 - shift;
emit_shf_indir is passing "0" as shift to __emit_shift which will
eventually be turned into 32 and it was OK because we truncate to
5-bit,
but before truncation, it will overflow the shift mask.
Yup, it silences the error for me.
