cobol: Correct libgcobol install directory and add components.
Set libgcobol/Makefile.am to define libdir and libsubdir the way libada does. Reorganize libgcobol/compat directory to group by emulation, not component. Move orphan gcc/udf/stored-char-length.cbl to the compat directory. Introduce new POSIX bindings. gcc/cobol/ChangeLog: PR cobol/122702 * Make-lang.in: Move stored-char-length.cbl to libgcobol. libgcobol/ChangeLog: PR cobol/122702 * Makefile.am: Set libdir and libsubdir per libada example. * Makefile.in: Regenerate. * compat/README.md: Revise per new directory structure. * compat/gnu/lib/CBL_ALLOC_MEM.cbl: Moved from compat/lib/gnu. * compat/gnu/lib/CBL_CHECK_FILE_EXIST.cbl: Moved from compat/lib/gnu. * compat/gnu/lib/CBL_DELETE_FILE.cbl: Moved from compat/lib/gnu. * compat/gnu/lib/CBL_FREE_MEM.cbl: Moved from compat/lib/gnu. * compat/gnu/udf/stored-char-length.cbl: New file. * compat/lib/gnu/CBL_ALLOC_MEM.cbl: Moved to compat/gnu/lib. * compat/lib/gnu/CBL_CHECK_FILE_EXIST.cbl: Moved to compat/gnu/lib. * compat/lib/gnu/CBL_DELETE_FILE.cbl: Moved to compat/gnu/lib. * compat/lib/gnu/CBL_FREE_MEM.cbl: Moved to compat/gnu/lib. * posix/cpy/psx-open.cpy: New file. * posix/shim/open.cc: New file. * posix/shim/stat.h: Add mode & flag bits for open.cc * posix/udf/posix-lseek.cbl: New file. * posix/udf/posix-open.cbl: New file. * posix/udf/posix-read.cbl: New file. * posix/udf/posix-write.cbl: New file. * xmlparse.cc: Quell context_t initialization-order warning. |

cobol: Introduce vendor-compatibility layer as user-defined functions.
Install COBOL UDFs in a target directory that includes the GCC version in its path, to permit side-by-side installation. Support compat library with COBOL POSIX bindings; support those binding with C functions in libgcobol as needed. Changes to the compiler to support POSIX binding and testing. Include developer conveniences -- Makefiles, bin/ and t/ directories -- to ensure UDFs compile and return reasonable results. These are not installed and do not affect how libgcobol is built. gcc/cobol/ChangeLog: * cdf.y: Install literals in symbol table. * genapi.cc (parser_alphabet): Use std::string for currency.

cobol: Mainly extends compilation and execution in finternal-ebcdic.
We expanded our extended testing regime to execute many testcases in EBCDIC mode as well as in ASCII. This exposed hundreds of problems in both compilation (where conversions must be made between the ASCII source code and the EBCDIC execution environment) and in run-time functionality, where results from calls to system routines and internal calculations that must be done in ASCII have to be converted to EBCDIC. These changes also switch to using FIXED_WIDE_INT(128) instead of REAL_VALUE_TYPE when initializing fixed-point COBOL variable types. This provides for accurate initialization up to 37 digits, instead of losing accuracy after 33 digits. These changes also support the implementation of the COBOL DELETE FILE (Format 2) statement. These changes also introduce expanded support for specifying character encodings, including support for locales. co-authored-by: Robert Dubner <rdubner@symas.com> co-authored-by: James K.

cobol: Implement the XML PARSE statement.
These changes implement the XML PARSE statement as described in the IBM specification. A repair to exception handling is included. Up until now, an exception after a successful file operation wasn't handled properly. A repair to value declarations for BINARY / COMP / COMP-4 / COMP-5 values now allows them to have digits to the right of the implied decimal point. Processing of the "S" PICTURE character has been normalized as well. Co-Authored-By: James K.
