2013-10-21 Bernd Edlinger <bernd.edlinger@hotmail.de>
Fix DECL_BIT_FIELD depencency on flag_strict_volatile_bitfields
and get_inner_reference returning different pmode for non-volatile
bit-field members dependent on flag_strict_volatile_bitfields.
* stor-layout.c (layout_decl): Remove special handling of
flag_strict_volatile_bitfields.
* expr.c (get_inner_reference): Don't use DECL_BIT_FIELD
if flag_strict_volatile_bitfields > 0 and TREE_THIS_VOLATILE.
