Nothing can happen until 4.2.0 for this issue really as we need a real copy
prop for structs.

Steven, if we increased the priority of the bug, what solution would you
envision? This is not in any way meant to be a rhetorical or sarcastic
question. My reading of the audit trail is that this bug is essentially a
feature request for a new optimization; given that, I don't think we can make
it release-critical. Am I misunderstanding?
Thanks,
-- Mark

* tree-sra.c (instantiate_element): Use BYTES_BIG_ENDIAN for
bit-field layout.
(sra_build_assignment): Likewise. Set up mask depending on
precision, not type.
(sra_build_bf_assignment): Use BYTES_BIG_ENDIAN. Don't overflow
computing bit masks.
(sra_build_elt_assignment): Don't view-convert from signed to
unsigned.
(sra_explode_bitfield_assignment): Use bit-field type if
possible. Use BYTES_BIG_ENDIAN.
