Port Bernd's fix to volatile bitfields
2010-12-02 Bernd Schmidt <bernds_cb1@t-online.de>
* expr.c (store_field): Avoid a direct store if the mode is larger
than the size of the bit field.
* stor-layout.c (layout_decl): If flag_strict_volatile_bitfields,
treat non-volatile bit fields like volatile ones.
* toplev.c (process_options): Disallow combination of
-fstrict-volatile-bitfields and ABI versions less than 2.
* config/arm/arm.c (arm_option_override): Don't enable
flag_strict_volatile_bitfields if the ABI version is less than 2.
