c-attribs.c (handle_packed_attribute): Test DECL_C_BIT_FIELD rather than DECL_INITIAL.
c-family/
* c-attribs.c (handle_packed_attribute): Test DECL_C_BIT_FIELD
rather than DECL_INITIAL.
(common_handle_aligned_attribute): Likewise.
c/
* c-decl.c (grokfield): Use SET_DECL_C_BIT_FIELD here if
width is non-NULL.
(finish_struct): Test DECL_C_BIT_FIELD instead of DECL_INITIAL,
don't SET_DECL_C_BIT_FIELD here.
cp/
* class.c (check_bitfield_decl): Retrieve and clear width from
DECL_BIT_FIELD_REPRESENTATIVE rather than DECL_INITIAL.
(check_field_decls): Test DECL_BIT_FIELD_REPRESENTATIVE rather than
DECL_INITIAL.
(remove_zero_width_bit_fields): Adjust comment.
* decl2.c (grokbitfield): Stash width into
DECL_BIT_FIELD_REPRESENTATIVE rather than DECL_INITIAL.
* pt.c (tsubst_decl): For DECL_C_BIT_FIELD, tsubst_expr
DECL_BIT_FIELD_REPRESENTATIVE rather than DECL_INITIAL for width.
objc/
* objc-act.c (check_ivars, gen_declaration): For OBJCPLUS look at
DECL_BIT_FIELD_REPRESENTATIVE rather than DECL_INITIAL.
