--- Comment #22 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Is it really pure RTL, therefore not used in tree? So the above patch using > BITS_BIG_ENDIAN for tree stuff would be incorrect to use it? I wouldn't say incorrect, just inappropriate and unnecessary. And, yes, it isn't used at the tree level and should stay so IMO. BYTES_BIG_ENDIAN alone already implicitly enforces a numbering on bits.
