These changes cause CALL ... USING BY VALUE to work properly for a wider range of COBOL variables types, values, and sizes. Some sizes of numeric-display variables didn't work, some didn't work for negative values, and floating-extended didn't work at all. Now they do. Fourteen new DejaGnu tests cover this repaired capability. gcc/cobol/ChangeLog: * genapi.cc (establish_using): Use a 128-bit type for float-extended; handle numeric-edited values of different sizes and signs correctly. (create_and_call): Use a 128-bit type for float-extended. libgcobol/ChangeLog: * Makefile.am: Temporarily continue to use -fno-strict-aliasing. * Makefile.in: Likewise. * libgcobol.cc (__gg__fetch_call_by_value_value): Simplify handling of FldFloat. (__gg__assign_value_from_stack): Likewise. (__gg__unstring): Avoid uninitialized variable error. (__gg__look_at_int128): New function useful for debugging. (__gg__look_at_pointer): Likewise. * xmlparse.cc (xml_event): Implement namespace XML. (cdataBlock): Likewise. (characters): Likewise. (__gg__xml_parse): Likewise. gcc/testsuite/ChangeLog: * cobol.dg/group2/USING_COMP-3_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_COMP-3_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_COMP-3_BY_VALUE.cob: New test. * cobol.dg/group2/USING_COMP-3_BY_VALUE.out: New test. * cobol.dg/group2/USING_FLOAT-SLX_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_FLOAT-SLX_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_FLOAT-SLX_BY_VALUE.cob: New test. * cobol.dg/group2/USING_FLOAT-SLX_BY_VALUE.out: New test. * cobol.dg/group2/USING_NumericDisplay_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_NumericDisplay_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_NumericDisplay_BY_VALUE.cob: New test. * cobol.dg/group2/USING_NumericDisplay_BY_VALUE.out: New test. * cobol.dg/group2/USING_Signed_-_COMP-3_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_Signed_-_COMP-3_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_Signed_-_COMP-3_BY_VALUE.cob: New test. * cobol.dg/group2/USING_Signed_-_COMP-3_BY_VALUE.out: New test. * cobol.dg/group2/USING_Signed_-_NumericDisplay_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_Signed_-_NumericDisplay_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_Signed_-_NumericDisplay_BY_VALUE.cob: New test. * cobol.dg/group2/USING_Signed_-_NumericDisplay_BY_VALUE.out: New test. * cobol.dg/group2/USING_Signed___COMP-3_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_Signed___COMP-3_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_Signed___COMP-3_BY_VALUE.cob: New test. * cobol.dg/group2/USING_Signed___COMP-3_BY_VALUE.out: New test. * cobol.dg/group2/USING_Signed___NumericDisplay_BY_REFERENCE.cob: New test. * cobol.dg/group2/USING_Signed___NumericDisplay_BY_REFERENCE.out: New test. * cobol.dg/group2/USING_Signed___NumericDisplay_BY_VALUE.cob: New test. * cobol.dg/group2/USING_Signed___NumericDisplay_BY_VALUE.out: New test.
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.
