PR preprocessor/63831
* c-cppbuiltin.c (c_cpp_builtins): Don't define __has_attribute
and __has_cpp_attribute here.
* c-ppoutput.c (init_pp_output): Set cb->has_attribute to
c_common_has_attribute.
* c-common.h (c_common_has_attribute): New prototype.
* c-lex.c (init_c_lex): Set cb->has_attribute to
c_common_has_attribute instead of cb_has_attribute.
(get_token_no_padding): New function.
(cb_has_attribute): Renamed to ...
(c_common_has_attribute): ... this. No longer static. Use
get_token_no_padding, require ()s, don't build TREE_LIST
unnecessarily, fix up formatting, adjust diagnostics, call
init_attributes.
* directives.c (lex_macro_node): Remove __has_attribute__ handling.
* internal.h (struct spec_node): Remove n__has_attribute__ field.
(struct lexer_state): Remove in__has_attribute__ field.
* macro.c (_cpp_builtin_macro_text): Handle BT_HAS_ATTRIBUTE.
* identifiers.c (_cpp_init_hashtable): Remove __has_attribute__
handling.
* init.c (builtin_array): Add __has_attribute and __has_cpp_attribute.
(cpp_init_special_builtins): Don't initialize __has_attribute
or __has_cpp_attribute if CLK_ASM or pfile->cb.has_attribute is NULL.
* traditional.c (enum ls): Remove ls_has_attribute,
ls_has_attribute_close.
(_cpp_scan_out_logical_line): Remove __has_attribute__ handling.
* include/cpplib.h (enum cpp_builtin_type): Add BT_HAS_ATTRIBUTE.
* pch.c (cpp_read_state): Remove __has_attribute__ handling.
* expr.c (eval_token): Likewise.
(parse_has_attribute): Removed.
* c-c++-common/cpp/pr63831-1.c: New test.
* c-c++-common/cpp/pr63831-2.c: New test.
