Reduced testcase (-O -m32):
struct S { unsigned int len; };
struct S foo (struct S);
struct S
bar (struct S x)
{
return ({ struct S a = x; foo (a); });
}
The C FE isn't inserting CLEANUP_POINT_EXPRs everywhere, so I wonder if the
r181332 change to add the clobber must not be limited to C++ or if e.g.
gimplify_cleanup_point_expr shouldn't set some (new) flag in *gimplify_ctxp for
the duration of the embedded gimplify_stmt call (and restore it from previous
value afterwards) and use this flag to decide whether to add the cleanup or
not.
