Hi Diego,

     This is a backport for two upstream patches into our 4.6 branch.
I submitted the first patch by Julian a while ago for backport but
Richard Earnshaw pointed out a problem with the first patch.  The second
patch from Joey fixes that problem.  This was tested on x86 and ARM.

                * expr.c (expand_expr_real_1): Only use BLKmode for volatile
                accesses which are not naturally aligned.

                * expr.c (expand_expr_real_1): Correctly handle strict volatile
                bitfield loads smaller than mode size.

                * gcc.dg/volatile-bitfields-1.c: New.

OK.


Diego.
