* expmed.c (strict_volatile_bitfield_p): Add bitregion_start
and bitregion_end parameters. Test for compliance with C++
memory model.
(store_bit_field): Adjust call to strict_volatile_bitfield_p.
Add fallback logic for cases where -fstrict-volatile-bitfields
is supposed to apply, but cannot.
(extract_bit_field): Likewise. Use narrow_bit_field_mem and
extract_fixed_bit_field_1 to do the extraction.
(extract_fixed_bit_field): Revert to previous mode selection algorithm.
Call extract_fixed_bit_field_1 to do the real work.
(extract_fixed_bit_field_1): New function.
testsuite:
* gcc.dg/pr23623.c: Update to test interaction with C++
memory model.
