Up until these changes, temporary intermediate alphanumeric string variables have been allocated on the stack. With the design change to a larger limit, that's no longer practical. Such variables are now placed on the heap, and we now have to take pains to free() that memory when we are done with it. gcc/cobol/ChangeLog: * gcobc: Adjust how -fPIC is applied, and other refinements. * gcobol.1: Documentation. * genapi.cc (parser_statement_end): New function. Deallocates temp char strings from the heap. (initialize_variable_internal): Ignore temp char strings. (compare_binary_binary): Formatting. (parser_end_program): Formatting. (parser_init_list): Formatting. (parser_exit_program): Formatting. (program_end_stuff): Formatting. (parser_exit): Formatting. (parser_perform_conditional): Formatting. (perform_outofline_before_until): Formatting. (parser_file_add): Formatting. (mh_source_is_literalA): Formatting. (psa_new_var_decl): Make cblc_field_t for intermediate_e alphanumerics program-static. (parser_symbol_add): Eliminate unnecessary code when type!=FldConditional; change handling of intermediate_e for FldAlphanumerics. * genapi.h (parser_end_program): New declaration. (parser_exit): Formatting. (parser_exit_program): Formatting. (parser_statement_end): New declaration. * lexio.cc (parse_replace_pairs): Change CDF handling. (cdftext::lex_open): Likewise. (cdftext::process_file): Likewise. * parse.y: Changes to MAXIMUM_ALPHA_LENGTH; refine return value types for various intrinsic functions; some CDF handling. * parse_ante.h (MAXLENGTH_FORMATTED_DATE): Eliminate constant.

(intrinsic_return_field): New declaration. (struct ffi_args_t): Changed debug message. (is_among): New declaration. * parse_util.h (intrinsic_return_field): New function. Works with the modified function_descrs[] table. * scan.l: Modified scanning. * scan_ante.h (class input_file_status_t): Likewise. (verify_ws): Likewise. (is_refmod): Likewise. * symbols.cc (symbols_update): Improved comment about a debug message. (symbol_temporaries): New function for temporaries on the heap that will have to be deallocated.

(new_alphanumeric): Eliminate capacity as a parameter. * symbols.h (cbl_dialect_str): Formatting. (MAXIMUM_ALPHA_LENGTH): Change comment and value. (IBM_MAXIMUM_ALPHA_LENGTH): Put parentheses around "size_t(1)<<31". (symbol_temporaries): New declaration. (symbol_temporary_alphanumerics): New declaration.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
