2023-07-26  Simon Sobisch <simonsobisch@gnu.org>

	* typeck.c (search_set_keys): improving SEARCH ALL syntax checks

2023-07-25  Simon Sobisch <simonsobisch@gnu.org>

	* codegen.c (output_entry_function): if COBOL CALL convention is
	  used, then only use local pointers for specifying not-passed
	  arguments, improving support for omission of trailing (optional)
	  parameters in CALL
	* config.def, codegen.c, typeck.c: added using-optional dialect option;
	  if set to "ok" the check for not-passed arguments will only be done
	  on program entry for all parameters not explicit specified as OPTIONAL
	* parser.y (_procedure_optional): added checks for cb_using_optional,
	  if OPTIONAL used and set to "warning", then reset it to "ok" after first
	  warning
	* codegen.c (output_entry_function): generate checks for
	  EC-PROGRAM-ARG-MISMATCH validating that non-optional arguments are
	  passed and if passed then checks its minimal size

2023-07-24  Simon Sobisch <simonsobisch@gnu.org>

	* parser.y (entry_statement): don't check parameter address
	  directly on ENTRY, because it just assigns it
	* codegen.c (output_internal_function, output_entry_function): moved
	  setting of non-passed parameters to NULL to entry function as we only
	  have ordinal CALL numbers available there; set BY VALUE parameters to
	  zero instead of NULL
	* codegen.c (output_field_no_target): extracted to reduce code duplication
	* typeck.c (cb_emit_call): fixed skipping memory-fence generation for
	  EXTERNAL/BASED sub-fields

2023-07-22  Simon Sobisch <simonsobisch@gnu.org>

	* field.c (compute_size): inspect field storage to check for
	  the appropriate field size limit
	* tree.h (cb_field): new flag_above_unbounded
	* tree.c (cb_field_has_unbounded), tree.h: removed; use
	  flag_above_unbounded in callers (typeck.c, cobc.c) instead
	* parser.y (occurs_clause): set flag_above_unbounded in parents

2023-07-21  Simon Sobisch <simonsobisch@gnu.org>

	* typeck.c (refmod_checks): fixed ec-bound-refmod checks for UNBOUNDED
	* field.c (compute_size): take fields before the UNBOUNDED field into
	  account when calculating its maximum elements;
	  fix compiler crash if DEPENDING field does not exist
	* parser.y (validated_field_reference): extracted from (identifier_field)
	  and used in all places with the exact same code

2023-07-20  Simon Sobisch <simonsobisch@gnu.org>

	* field.c (copy_validation): new function

	* typeck.c (cb_build_move_literal): optimize to cb_build_move_num_zero in
	  more cases

2023-07-13  Simon Sobisch <simonsobisch@gnu.org>

	* pplex.l (cb_ppecho_direct, output_pending_newlines): output only up
	  to 9 empty lines, for more empty lines in the preparsed output file
	  generate a matching #line directive, this saves both space and serves
	  as a workaround for an unclear scanner bug that may happen with huge
	  amounts of empty lines
	* pplex.l (switch_to_buffer): don't re-strdup the filename
	* parser.y (emit_statement): changed from define to inline function
	* codegen.c: complete output of program's end source location if requested
	* scanner.l: handle line directive in any state
	* warning.def, typeck.c (validate_move), cobc.c (process_command_line):

2023-07-06  Fabrice Le Fessant <fabrice.le_fessant@ocamlpro.com>

	* replace.c: rewrite the code for preprocessing with a two-phase
	  algorithm. The first phase performs COPY REPLACING on the stream
	  of tokens, while the second phase perform REPLACE on the resulting
	  stream of tokens. This rewriting is closer to the COBOL standard
	  and fixes bug #831 partially.
	* cobc.c: flag -P now accepts - as argument to mean stdout

2023-07-05  Fabrice Le Fessant <fabrice.le_fessant@ocamlpro.com>

	* flag.def/cobc.c: new flags -fno-ttimestamp to suppress timestamp
	  in listing headers, and -fttitle=<TITLE>, so that listings can be
	  compared accross different versions and dates. This patch partially
	  implements feature-request #294.
	  Replace numeric constants in flags and switch by a constant macro
	  CB_FLAG_GETOPT_. Remove unused 'case 6:' for -fdefaultbyte that is
	  now handled in config.c

	  to removing (user_func_upper) from codegen.c
	* typeck.c (cb_encode_program_id): check for path separators now backwards

	  reported by AddressSanitizer
	* reserved.c: TOP as mnemonic CB_FEATURE_FORMFEED
	* parser.y: added top_clause as we won't be able to define the mnemonic
	  as it duplicates a reserved word (FIXME: general adjustment needed)

2019-08-11  Simon Sobisch <simonsobisch@gnu.org>

	* scanner.l, config.def: added support for HP COBOL octal literals
	  unfinished as its type should be context-sensitive (so far chosen
	  by scanner.l), configured by dialect configuration hp-octal-literals
	* flag.def, cobc.c, help.c: moved -f[no-]ibmcomp out of flags.def and
	  activated the "non-flag" as "normal option"

	* tree.c, tree.h: added struct cb_next_elem to be used for any structure
	  that has a next pointer as first entry, to be used by (cb_next_length)
	  to get the size of the complete entry (only reasonable to call with the
	  "main" entry normally attached to a program)
	* typeck.c (cb_validate_program_data): set alphabet->custom_list to error
	  node once seen as bad, partially limited variable scope
	* tree.c (validate_file): explicit check for number of keys (limited
	  to MAX_FILE_KEYS, currently 255, per file)

2019-06-06  Simon Sobisch <simonsobisch@gnu.org>

	  on fields that got an error raised before
	* parser.y: removed duplicate parts for integer handling,

	  by any known COBOL dialect, must be "COL/LINE + 1 / - 1")
	* parser.y (set_record_size): extracted from (record_clause) variants
	* config.def: added records-mismatch-record-clause
	* parser.y (set_record_size), tree.c (finalize_file): handle record sizes
	  that don't match the record clause (auto-adjust file min/max) via

	* parser.y (restore_backup_pos): extracted for common use
	* parser.y (evaluate_when_list), typeck.c (build_evaluate): assign and

2019-05-30  Simon Sobisch <simonsobisch@gnu.org>

	* parser.y, reserved.c, tree.h, config.def: FR #311 added Fujitsu
	  specification of call convention by WITH ... LINKAGE,

	* tree.c (cb_int_hex): fixed to not adjust hex-attribute of cached integers
	  by using a different cache
	* codgen.c, tree.c, tree.h: deactivated hex-attribute of CB_INTEGER for now
	  (marked with USE_INT_HEX) as this increases the struct and we *should*
	  pass the flags as constants in any case
	* tree.c (cb_int, cb_int_hex): disabled caching of integer values (other
	  than 0-8) for now (test, reactivate by defining CACHED_INTEGERS=1) as the
	  necessary lookup can take much time with many different integer values

	  COLLATING SEQUENCE OF key

2019-03-15  Simon Sobisch <simonsobisch@gnu.org>

	* Makefile.am: drop yacc-compatibility warnings via AM_YFLAGS -Wno-yacc
	  as only bison is supported in any case

2019-03-14  Simon Sobisch <simonsobisch@gnu.org>

	* config.c: hand-merged change 2015-04-27 with an option to go back,

	* codegen.c (output_call): for static calls only generate parameters
	  up to the maximum number of the call, otherwise the static calls
	  cannot be resolved at compile time.
	  Note: currently only done for system library calls, we'd need an
	  external repository for doing this with other calls, too.

	  for early/late aborting depending on number of errors, defaulting
	  to the old value: 100
	* cobc.c: added -W[no-]fatal-errors for aborting on first error
	  note: this option takes precedence over -fmax-errors

	  snprintf returns -1 in MSC and on HPUX if max is reached

2017-04-13  Simon Sobisch <simonsobisch@gnu.org>

	* cobc.c (print_fields, print_88_values): removed indent parameter as
	  we no longer indent by level number

	  prototype.

2017-04-17  Edward Hart <edward.dan.hart@gmail.com>

	* cobc.c (process_translate): reverse program list in place so that
	  current_program doesn't point to last program in file (see bug #265).
	* codegen.c: reinstated local variable current_prog removed in
	  r1309. (codegen) would leave current_program pointing to the last
	  program in a file, from which you cannot get the first program. This
	  caused the listing code to break (bug #265) because it assumed
	  current_program would point to the first program in the file.

2016-07-18  Edward Hart <edward.dan.hart@gmail.com>

	* parser.y (screen_or_device_display): changed permitted DISPLAY

	* codegen.c: when emitting source for a function entry, if cob_call_params
	  is zero, and cob_module is not set, set cob_call_params to the number of
	  arguments in GnuCOBOL using_list. Need to document that C can't call a
	  GnuCOBOL function with zero arguments if GnuCOBOL expects at least one,
	  even if all are optional from the GnuCOBOL perspective.  Except for that
	  edge case, this fixes bug #208 (and possibly others).
	* codegen.c: allow for ENTRY lookup inside main module.

2016-07-15  Edward Hart <edward.dan.hart@gmail.com>

	* scanner.l, pplex.l: fixed bug #269. GnuCOBOL now gobbles redundant

	* typeck.c: fixed bug #264, where fields of category CB_CATEGORY_UNKNOWN
	  were rejected in the AT clause despite being numeric (or having only
	  numeric children).
	* typeck.c (valid_screen_pos): removed extension to AT clause where less
	  than 4 digits was permitted (I'd added this because I thought leading
	  zeroes were truncated from literals).

2016-06-30  Edward Hart <edward.dan.hart@gmail.com>

	* pplex.l (is_condition_directive_clause): fixed bug #263 where >>IF's
	  where not detected inside false >>IF's.

	  replacing while loops with for where appropriate) and simplified and
	  modularised code.
