Well, the list of problems is endless it seems - we are not consistent in
how we build accesses for
declD.1.u1.a.align = 13;
vs.
decl$u1$a$align_5 = BIT_FIELD_REF MEM[(unnamed-unsigned:24 *)declD.2],
24, 0;

wip patch
Testcase that shows this behavior is gcc.dg/tree-ssa/vrp14.c which is
miscompiled.

Martin, can you have a look here? All this build_ref_for_offset should
now be very easy. But we need to have the original access tree that we
replace as well. The built access should simply be
fold_build2

prototype
sth like this, with the FIXME resolved (it's not clear which is the reference
we are replacing at each
--- Comment #7 from rguenth at gcc dot gnu dot org 2010-07-18 21:22 ---
More like
if (TREE_CODE (*expr) == MEM_REF
TREE_OPERAND (*expr, 0) != ADDR_EXPR)
*expr = fold_build2 (MEM_REF, exp_type,
TREE_OPERAND (*expr, 0),

In case it may help, let me mention that other test programs for our library
show:
internal compiler error: in refs_may_alias_p_1, at tree-ssa-alias.c:1023
or:
warning: '#'mem_ref' not supported by
17 matches
