Represent column numbers using line-map's source_location.
The "next available source_location" is now managed internally by
line-maps.c rather than by clients.
* line-map.h (struct line_map): New field column_bits.
<from_line>: Rename field to start_location.
(struct line_maps): New fields highest_location and max_column_hint.
(linemap_check_files_exited): New declaration.
(linemap_line_start): New declaration.
(linemap_add): Remove from_line parameter; use highest_location field.
(SOURCE_LINE, LAST_SOURCE_LINE): Modify to use column_bits.
(SOURCE_COLUMN, LAST_SOURCE_LINE_LOCATION): New macros.
(CURRENT_LINE_MAP): Remove macro.
(linemap_position_for_column): New inline function.
* line-map.c (linemap_init): Clear new fields.
(linemap_check_files_exited): New function, extracted from ...
(linemap_free): Use linemap_check_files_exited.
(linemap_add): Remove from_line parameter. Various updates.
(linemap_line_start): New function.
(linemap_lookeup): Update for new field names.
* cpphash.h (struct cpp_reader) <map>: Field removed. Because
linemap_position_for_column may unpredictably change the current map,
it is cleaner and simpler for us to not cache it in cpp_reader.
(struct cpp_buffer): New sysp field.
Changed warned_cplusplus_comments and from_stage3 to bitfields.
* cppinit.c (cpp_read_min_file): pfile->map no longer exists.
* cpplib.c (do_line, do_linemarker, _cpp_do_file_change): Get
current map using linemap_lookup.
(do_linemarker): Also set buffer's sysp field.
(destringize_and_run): No longer need to decrement current line.
* cppfiles.c (_cpp_stack_file): Set sysp from and in buffer.
(search_path_head, open_file_failed): Use buffer's sysp.
(cpp_make_system_header): Get current map using linemap_lookup.
Also set buffer's sysp flag.
* cppmacro.c (_cpp_builtin_macro_text): Likewise use linemap_lookup.
* cpphash.h (CPP_INCREMENT_LINE): New macro.
(struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ...
(struct cpp_reader): ... and adding saved_line_base field.
* cpptrad.c (_cpp_overlay_buffer, _cpp_remove_overlay):
Update accordingly. Don't adjust line.
(_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE.
* cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ...
(cpp_in_system_header): ... new inline function, using buffer's sysp.
* cpperror.c (_cpp_begin_message): Update to use cpp_in_system_header.
* cpplex.c (_cpp_lex_direct): Likewise.
* cppmacro.c (_cpp_builtin_macro_text): Likewise.
* cppmacro.c (_cpp_create_definition): Use buffer's sysp field.
* cpplib.h (struct cpp_token): Rename line field to src_loc.
Remove col field as it is now subsumed by src_loc.
* cpperror.c: Update various field, parameter, and macro names.
(print_location): If col==0, try SOURCE_COLUMN of line.
(cpp_error): Use cur_token's src_loc field, rather than line+col.
* cpplib.c (do_diagnostic): Token's src_loc fields replaces line+col.
* cpplex.c (_cpp_process_line_notes, _cpp_lex_direct,
_cpp_skip_block_comment): Use CPP_INCREMENT_LINE.
(_cpp_temp_token): Replace cpp_token's line+col fields by src_loc.
(_cpp_get_fresh_line): Don't need to adjust line for missing newline.
(_cpp_lex_direct): Use linemap_position_for_column.
* c-ppoutput.c (maybe_print_line, print_line): Don't take map
parameter. Instead get it from the line_table global. Adjust callers.
(print): Remove map field. Replace line field to src_line.
(init_pp_output, account_for_newlines, maybe_print_line): Adjust.
(cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
(pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
* cpptrad.c (copy_comment): Rename variable.
* c-lex.c (map): Remove static variable, for same reason we removed
cpp_reader's map field.
(cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
to call linemap_lookup.
(cb_line_change): Token's line field replaced by src_loc.
(fe_file_change): Use MAINFILE_P and LAST_SOURCE_LINE macros.
Don't save new_map.
* cpphash.h, cpperror.c, cpplib.h: Some renames of fileline to
source_location.

linemap_position_for_column may unpredictably change the current map,
it is cleaner and simpler for us to not cache it in cpp_reader.
(struct cpp_buffer): New sysp field.
Changed warned_cplusplus_comments and from_stage3 to bitfields.
* cppinit.c (cpp_read_min_file): pfile->map no longer exists.

(init_pp_output, account_for_newlines, maybe_print_line): Adjust.
(cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
(pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
* cpptrad.c (copy_comment): Rename variable.
* c-lex.c (map): Remove static variable, for same reason we removed
cpp_reader's map field.
(cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
to call linemap_lookup.
(cb_line_change): Token's line field replaced by src_loc.
(fe_file_change): Use MAINFILE_P and LAST_SOURCE_LINE macros.
Don't save new_map.

c: C2x __has_c_attribute
C2x adds the __has_c_attribute preprocessor operator, similar to C++
__has_cpp_attribute.
GCC implements __has_cpp_attribute as exactly equivalent to
__has_attribute. (The documentation says they differ regarding the
values returned for standard attributes, but that's actually only a
matter of the particular nonzero value returned not being specified in
the documentation for __has_attribute; the implementation makes no
distinction between the two.)
I don't think having them exactly equivalent is actually correct,
either for __has_cpp_attribute or for __has_c_attribute.
Specifically, I think it is only correct for __has_cpp_attribute or
__has_c_attribute to return nonzero if the given attribute is
supported, with the particular pp-tokens passed to __has_cpp_attribute
or __has_c_attribute, with [[]] syntax, not if it's only accepted in
__attribute__ or with gnu:: added in [[]]. For example, they should
return nonzero for gnu::packed, but zero for plain packed, because
[[gnu::packed]] is accepted but [[packed]] is ignored as not a
standard attribute.
This patch implements that for __has_c_attribute, leaving any changes
to __has_cpp_attribute for the C++ maintainers. A new
BT_HAS_STD_ATTRIBUTE is added for __has_c_attribute (which I think,
based on the above, would actually be correct to use for
__has_cpp_attribute as well). The code in c_common_has_attribute that
deals with scopes has its C++ conditional removed; instead, whether
the language is C or C++ is used only to determine the numeric values
returned for standard attributes (and which standard attributes are
handled there at all). A new argument is passed to
c_common_has_attribute to distinguish BT_HAS_STD_ATTRIBUTE from
BT_HAS_ATTRIBUTE, and that argument is used to stop attributes with no
scope specified from being accepted with __has_c_attribute unless they
are one of the known standard attributes and so handled specially.
Although the standard specify constants ending with 'L' as the values
for the standard attributes, there is no correctness issue with the
lack of code in GCC to add that 'L' to the expansion:
__has_c_attribute and __has_cpp_attribute are expanded in #if after
other macro expansion has occurred, with no semantics being specified
if they occur outside #if, so there is no way for a conforming program
to inspect the exact text of the expansion of those macros, only to
use the resulting pp-number in a #if expression, where long and int
have the same set of values.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

Represent column numbers using line-map's source_location.
The "next available source_location" is now managed internally by
line-maps.c rather than by clients.
* line-map.h (struct line_map): New field column_bits.
<from_line>: Rename field to start_location.
(struct line_maps): New fields highest_location and max_column_hint.
(linemap_check_files_exited): New declaration.
(linemap_line_start): New declaration.
(linemap_add): Remove from_line parameter; use highest_location field.
(SOURCE_LINE, LAST_SOURCE_LINE): Modify to use column_bits.
(SOURCE_COLUMN, LAST_SOURCE_LINE_LOCATION): New macros.
(CURRENT_LINE_MAP): Remove macro.
(linemap_position_for_column): New inline function.
* line-map.c (linemap_init): Clear new fields.
(linemap_check_files_exited): New function, extracted from ...
(linemap_free): Use linemap_check_files_exited.
(linemap_add): Remove from_line parameter. Various updates.
(linemap_line_start): New function.
(linemap_lookeup): Update for new field names.
* cpphash.h (struct cpp_reader) <map>: Field removed. Because
linemap_position_for_column may unpredictably change the current map,
it is cleaner and simpler for us to not cache it in cpp_reader.
(struct cpp_buffer): New sysp field.
Changed warned_cplusplus_comments and from_stage3 to bitfields.
* cppinit.c (cpp_read_min_file): pfile->map no longer exists.
* cpplib.c (do_line, do_linemarker, _cpp_do_file_change): Get
current map using linemap_lookup.
(do_linemarker): Also set buffer's sysp field.
(destringize_and_run): No longer need to decrement current line.
* cppfiles.c (_cpp_stack_file): Set sysp from and in buffer.
(search_path_head, open_file_failed): Use buffer's sysp.
(cpp_make_system_header): Get current map using linemap_lookup.
Also set buffer's sysp flag.
* cppmacro.c (_cpp_builtin_macro_text): Likewise use linemap_lookup.
* cpphash.h (CPP_INCREMENT_LINE): New macro.
(struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ...
(struct cpp_reader): ... and adding saved_line_base field.
* cpptrad.c (_cpp_overlay_buffer, _cpp_remove_overlay):
Update accordingly. Don't adjust line.
(_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE.
* cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ...
(cpp_in_system_header): ... new inline function, using buffer's sysp.
* cpperror.c (_cpp_begin_message): Update to use cpp_in_system_header.
* cpplex.c (_cpp_lex_direct): Likewise.
* cppmacro.c (_cpp_builtin_macro_text): Likewise.
* cppmacro.c (_cpp_create_definition): Use buffer's sysp field.
* cpplib.h (struct cpp_token): Rename line field to src_loc.
Remove col field as it is now subsumed by src_loc.
* cpperror.c: Update various field, parameter, and macro names.
(print_location): If col==0, try SOURCE_COLUMN of line.
(cpp_error): Use cur_token's src_loc field, rather than line+col.
* cpplib.c (do_diagnostic): Token's src_loc fields replaces line+col.
* cpplex.c (_cpp_process_line_notes, _cpp_lex_direct,
_cpp_skip_block_comment): Use CPP_INCREMENT_LINE.
(_cpp_temp_token): Replace cpp_token's line+col fields by src_loc.
(_cpp_get_fresh_line): Don't need to adjust line for missing newline.
(_cpp_lex_direct): Use linemap_position_for_column.
* c-ppoutput.c (maybe_print_line, print_line): Don't take map
parameter. Instead get it from the line_table global. Adjust callers.
(print): Remove map field. Replace line field to src_line.
(init_pp_output, account_for_newlines, maybe_print_line): Adjust.
(cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
(pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
* cpptrad.c (copy_comment): Rename variable.
* c-lex.c (map): Remove static variable, for same reason we removed
cpp_reader's map field.
(cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
to call linemap_lookup.
(cb_line_change): Token's line field replaced by src_loc.
(fe_file_change): Use MAINFILE_P and LAST_SOURCE_LINE macros.
Don't save new_map.
* cpphash.h, cpperror.c, cpplib.h: Some renames of fileline to
source_location.

__has_attribute. The already parsed arguments

are put into a buffer, which is then preprocessed
|
|
|
|
and the result is fed to _cpp_push_text_context

|
with disabled expansion, where the ISO preprocessor
|

parses it. While in traditional preprocessing
|

macro arguments aren't immediately expanded, they in

the end are because the macro with replaced arguments

is preprocessed again. For the builtin function-like

if we don't preprocess them, they would behave

very differently from ISO preprocessor handling

of those builtin macros. So, this handling is
|
|
|
|
more similar to traditional preprocessing of

#if directives, where we also keep preprocessing
|
|
|
|
until everything is expanded, and then feed the

|
|
|
result with disabled expansion to ISO preprocessor

for handling the directives. */

(linemap_line_start): New declaration.
(linemap_add): Remove from_line parameter; use highest_location field.
(SOURCE_LINE, LAST_SOURCE_LINE): Modify to use column_bits.
(SOURCE_COLUMN, LAST_SOURCE_LINE_LOCATION): New macros.
(CURRENT_LINE_MAP): Remove macro.
(linemap_position_for_column): New inline function.
* line-map.c (linemap_init): Clear new fields.
(linemap_check_files_exited): New function, extracted from ...
(linemap_free): Use linemap_check_files_exited.
(linemap_add): Remove from_line parameter. Various updates.
(linemap_line_start): New function.
(linemap_lookeup): Update for new field names.
* cpphash.h (struct cpp_reader) <map>: Field removed. Because
linemap_position_for_column may unpredictably change the current map,
it is cleaner and simpler for us to not cache it in cpp_reader.
(struct cpp_buffer): New sysp field.
Changed warned_cplusplus_comments and from_stage3 to bitfields.
* cppinit.c (cpp_read_min_file): pfile->map no longer exists.
* cpplib.c (do_line, do_linemarker, _cpp_do_file_change): Get
current map using linemap_lookup.
(do_linemarker): Also set buffer's sysp field.
(destringize_and_run): No longer need to decrement current line.
* cppfiles.c (_cpp_stack_file): Set sysp from and in buffer.
(search_path_head, open_file_failed): Use buffer's sysp.
(cpp_make_system_header): Get current map using linemap_lookup.
Also set buffer's sysp flag.
* cppmacro.c (_cpp_builtin_macro_text): Likewise use linemap_lookup.
* cpphash.h (CPP_INCREMENT_LINE): New macro.
(struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ...
(struct cpp_reader): ... and adding saved_line_base field.
* cpptrad.c (_cpp_overlay_buffer, _cpp_remove_overlay):
Update accordingly. Don't adjust line.
(_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE.
* cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ...
(cpp_in_system_header): ... new inline function, using buffer's sysp.
* cpperror.c (_cpp_begin_message): Update to use cpp_in_system_header.
* cpplex.c (_cpp_lex_direct): Likewise.
* cppmacro.c (_cpp_builtin_macro_text): Likewise.
* cppmacro.c (_cpp_create_definition): Use buffer's sysp field.
* cpplib.h (struct cpp_token): Rename line field to src_loc.
Remove col field as it is now subsumed by src_loc.
* cpperror.c: Update various field, parameter, and macro names.
(print_location): If col==0, try SOURCE_COLUMN of line.
(cpp_error): Use cur_token's src_loc field, rather than line+col.
* cpplib.c (do_diagnostic): Token's src_loc fields replaces line+col.
* cpplex.c (_cpp_process_line_notes, _cpp_lex_direct,
_cpp_skip_block_comment): Use CPP_INCREMENT_LINE.
(_cpp_temp_token): Replace cpp_token's line+col fields by src_loc.
(_cpp_get_fresh_line): Don't need to adjust line for missing newline.
(_cpp_lex_direct): Use linemap_position_for_column.
* c-ppoutput.c (maybe_print_line, print_line): Don't take map
parameter. Instead get it from the line_table global. Adjust callers.
(print): Remove map field. Replace line field to src_line.
(init_pp_output, account_for_newlines, maybe_print_line): Adjust.
(cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
(pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
* cpptrad.c (copy_comment): Rename variable.
* c-lex.c (map): Remove static variable, for same reason we removed
cpp_reader's map field.
(cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
to call linemap_lookup.
(cb_line_change): Token's line field replaced by src_loc.
(fe_file_change): Use MAINFILE_P and LAST_SOURCE_LINE macros.
Don't save new_map.
* cpphash.h, cpperror.c, cpplib.h: Some renames of fileline to
source_location.

Preserve original spellings of extended identifiers.
This patch makes cpplib track the original spellings of extended
identifiers, as well as the canonical UTF-8 version, in order to
follow standard semantics properly without needing a convoluted and
undocumented canonicalization in translation phase 1 (see bug 9449
comments 39-46 regarding such a canonicalization).
The spelling is tracked in cpp_identifier and cpp_macro_arg without
making cpp_token any larger. The original spelling is used for checks
of duplicate macro definitions, stringizing (see the C++ tests added;
this case is only an issue for C++ not C because C makes it
implementation-defined whether a \ is inserted before the \ of a UCN
in a string or character constant when stringizing, while C++ does
not), pasting (relevant when the result is then stringized for C++)
and when macro definitions are output as text (e.g. for -d options).
Once a macro has been defined, only the original spelling of the
argument names needs keeping in the argument list. While it is being
defined, however, both spellings are needed: the original one for
subsequent saving for checks of duplicate macro definitions, and the
canonical one which is the node marked specially to generate macro
argument tokens rather than normal identifier tokens. The buffer that
is used to save the original values of the identifier tokens is
changed so that it stores both those original values and a pointer to
the canonical hash nodes, so that those canonical nodes can be found
when their values need restoring after the macro definition has been
parsed.
I believe this covers the known standards issues in extended
identifiers support (the remaining unimplemented C99 areas in GCC all
being floating-point-related), except for C++ translation of extended
characters to UCNs in phase 1 (which I have no plans to work on).
There are however probably issues left with handling of extended
identifiers in other places, as listed in
<https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00337.html> (those
issues are generally the sort of thing that could be addressed as bugs
outside development stage 1). (The bulk of the potential issues Zack
was concerned about in 2003-5, that resulted in extended identifiers
being disabled in the absence of -fextended-identifiers, were
effectively eliminated by the audit and fixes I did in 2009, however;
that todo list reflects what was left over after that audit.)
Bootstrapped with no regressions on x86_64-unknown-linux-gnu.
