varasm.c (initializer_constant_valid_for_bitfield_p): Return true for REAL_CST as well.
* varasm.c (initializer_constant_valid_for_bitfield_p): Return true
for REAL_CST as well.
(output_constructor): Use RECORD_OR_UNION_TYPE_P predicate.
In the bitfield case, if the value is a REAL_CST, convert it first to
an INTEGER_CST.
