cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.

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.

(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.

(skip_line_comment, skip_block_comment, skip_whitespace,
parse_number, parse_string, trigraph_ok, save_comment,
adjust_column, _cpp_get_line): New implementations.
(lex_token): New function. Lexes a token at a time, looking
forwards. Contains most of the guts of the old lex_line.
(lex_line): New implementation, using lex_token to obtain
individual tokens.
(cpp_scan_buffer): Use the token's line, not the list's line.
* cpplib.c (_cpp_check_directive, _cpp_check_linemarker):
New implementations.
(do_assert): Don't bother setting the answer's list's line.
(cpp_push_buffer): Initialise new pfile and read_ahead members

(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.

(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.

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.

* 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.

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.

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.

(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.

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.

* 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 ...

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.

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.

That buffer is used for growing allocations when saving macro

replacement lists in a #define, and when parsing an answer to an
|
|
|
|
|
assertion in #assert, #unassert or #if (and therefore possibly
|
|
|
|
|
whilst expanding macros). It therefore must not be used by any

|
|
|
|
|
the macro expander.
